The Devastation of Baal

Baal and the Sons of Sanguinius

Baal, in the late-millennium Imperial cartographic notation, is a death-world. The world's atmosphere had been chemically poisoned during a pre-Imperial nuclear engagement that the wider Imperium does not fully reconstruct; the surface temperatures range from forty degrees Celsius at the equatorial poles to seventy degrees Celsius in the deep deserts; the radiation background on the surface exceeds Imperial baseline-human tolerance by approximately one order of magnitude. The wider Baal system's two inhabited moons — Baal Primus and Baal Secundus — are similarly rad-blasted and similarly inhospitable, though to varying degrees: Baal Secundus had been the world on which Sanguinius was raised during his post-warp exile, and the moon's population — the human tribes from which the Blood Angels Chapter draws its aspirants to the present day — had adapted to the moon's conditions through approximately ten thousand years of post-Heresy genetic drift that the Adeptus Mechanicus has subsequently catalogued as among the most extensive baseline-human adaptations in the Imperial record.

The Blood Angels Chapter, formed from the surviving Blood Angels Legion in the post-Heresy reorganisation that the Codex Astartes required, had maintained Baal as its institutional home for the ten thousand years between the Heresy and the Devastation. The Chapter's gene-seed, inherited from Sanguinius, carried a specific institutional inheritance that distinguished it from the wider Astartes gene-stock: the Red Thirst, a primarch-derived psychological condition that manifested in Blood Angels Astartes as an intermittent compulsion toward bloodletting in combat, and the Black Rage, a more severe form of the same condition that periodically rendered Blood Angels Astartes operationally incoherent and that the Chapter formally institutionalised as the Death Company — the suicide-formation of Black-Rage-afflicted Astartes whom the Chapter committed to forward engagements in the expectation that the engagement would resolve their condition through their deaths.

The Sanguinius-line Successor Chapters — the Astartes Chapters founded from Blood Angels gene-seed in the post-Heresy Foundings — numbered, by the late-millennium Imperial count, approximately twenty Chapters of varying operational character. The Successors included the Lamenters (a Cursed-Founding Chapter perennially under-strength and considered theologically suspect), the Flesh Tearers (a Successor whose Red Thirst manifestation was substantially more severe than the parent Chapter's, and whose Chapter Master Gabriel Seth had been an outspoken critic of the wider Imperial cultural restrictions on Astartes operations), and the Knights of Blood (an Excommunicate Traitoris Chapter that had been declared renegade in the Forty-First Millennium but whose surviving Astartes had reverted to Sanguinius-line institutional loyalty in the years preceding the Devastation). The Successors had not, in the ten thousand years since their Founding, gathered as a single operational entity. The Devastation would be the engagement that required them to do so.

Hive Fleet Leviathan

Hive Fleet Leviathan, by the Imperium's Adeptus Astra Telepathica intelligence estimates that the Inquisition had been quietly compiling for the preceding several decades, was the largest individual Tyranid Hive Fleet the Imperium had ever documented. The Hive Fleet had been first identified by Imperial reconnaissance in approximately 990.M41, when long-range Imperial Navy patrols had detected the characteristic Shadow in the Warp — the psychic disruption that Tyranid Hive Fleets generate as a side-effect of their Hive Mind communications — emanating from the galactic south at intensities that the Astra Telepathica had not previously catalogued. The Hive Fleet had been moving toward the galactic north since its identification, eating through approximately two thousand Imperial worlds across the intervening decade and consuming the biological mass of those worlds into the Hive Fleet's continued growth.

The Tyranid operational model that Leviathan instantiated was, by Imperial xeno-biological understanding, a coordinated bioform-construction engagement on a scale that the Imperium's conventional military doctrine had no comparable framework for. The Hive Fleet was, in its operational logic, a single coordinated organism — the Hive Mind, expressed across billions of individual bioform instances, coordinated through synaptic command structures that operated at warp-level psychic intensity, and committed to the comprehensive consumption of biological mass across every world the Hive Fleet encountered. The bioforms ranged from the smallest Hormagaunts and Termagants at the squad-equivalent level to the largest Bio-titans at the super-heavy equivalent level; the entire bioform inventory was, in the Hive Mind's operational logic, a single integrated weapon system that the Mind deployed against engagement targets in whatever configuration the engagement required.

Leviathan's approach to Baal had been telegraphed, in the Astra Telepathica intelligence picture that the Inquisition had been compiling, for several years prior to the engagement. The Hive Fleet's trajectory analysis had identified Baal as a likely target by approximately 996.M41; the Imperial intelligence community had quietly briefed the Blood Angels on the assessment by 997.M41; the Blood Angels had begun preparing defensive measures by 998.M41. The preparation included the strengthening of orbital defences at Baal proper, the consolidation of Chapter veteran formations within the Fortress of Hera, and the issuance of the call to the Sanguinius-line Successors that would eventually assemble the largest single-primarch gene-line concentration the Imperium had organised since the Heresy. The call was issued by Dante personally. The call had not, in the Chapter's ten-thousand-year history, been issued before.

Sons of Sanguinius. Wherever you are. Whatever you have become. Come home. Come home now. The hour is upon us.

— Commander Dante, opening line of the All-Successors Astropathic call broadcast from Baal in 998.M41 — the call reached every Sanguinius-line Chapter house within forty days and was answered by every Chapter that received it, including the Cursed-Founding Lamenters and the Excommunicate Knights of Blood

Dante's Call

The Astropathic call that Dante issued in 998.M41 was, by every Imperial protocol of inter-Chapter communication, an extraordinary operation. Astartes Chapters in the late-millennium Imperium operated under the standing assumption of institutional autonomy; Chapter Masters did not, as a general rule, issue calls to other Chapter Masters that required operational coordination at the Chapter-strength level, and the Codex Astartes' foundational structure had been designed to prevent the kind of multi-Chapter concentration that Dante's call was now attempting to organise. The call was, in formal Codex terms, a transgression of the Codex's institutional intent. Dante issued it anyway. His operational reasoning, articulated in the dispatches that accompanied the call, was that the Codex's prohibition on multi-Chapter concentrations had been engineered for engagements against Imperial-traitor or Imperial-renegade enemies, and that an existential threat to a Sanguinius-line gene-stock from a xenos Hive Fleet of Leviathan's scale was not the engagement category the Codex's prohibition had been written for. The wider Imperium's institutional reaction to the call's issuance was, in the months that followed, divided; the High Lords of Terra received the dispatch reporting the call but did not formally rule on its admissibility, leaving the operational question of whether the Successors would answer to the Successors themselves.

They answered. The Lamenters, the Cursed-Founding Chapter whose institutional history was a sustained series of operational tragedies and whose Chapter strength at the call's receipt was approximately four hundred Astartes — a fraction of the Codex-standard thousand — committed their entire combat-effective complement to Baal under the personal command of Chapter Master Erwin Ramos. The Flesh Tearers, whose Red Thirst severity had made them institutionally controversial across the post-Heresy period and whose operational culture under Gabriel Seth was the most direct-combat-oriented in the Sanguinius gene-line, committed approximately seven hundred Astartes. The Angels Encarmine, the Angels Sanguine, the Angels Vermillion, the Angels Numinous, the Carmine Blades, the Blood Drinkers, and approximately fifteen smaller Sanguinius-line Chapters committed varying fractions of their Chapter strength, with most Chapters committing between fifty and ninety percent of their combat-effective Astartes. The Knights of Blood, who had been declared Excommunicate Traitoris by the Inquisition in 800.M41 and whose subsequent operational status had been formally that of renegades, committed approximately three hundred Astartes under the personal command of their Chapter Master; the Inquisition did not formally lift the Excommunication, but the Inquisition also did not order the Knights of Blood's engagement at Baal to be opposed.

The total assembly, by the time the last Successor formations arrived in the Baal system in early 999.M41, was approximately thirty thousand Sanguinius-line Astartes. The number was, by every Imperial subsequent assessment, the largest single concentration of one primarch's gene-line that the Imperium had organised since the immediate post-Heresy period. The concentration occupied substantially the entirety of Baal's and Baal Secundus's orbital defence infrastructure, required the Chapter's quartermaster operations to operate at a scale they had not previously been required to operate at, and generated logistical demands that the Baal civilian administration had to coordinate with the Adeptus Munitorum to satisfy. The assembly was, in operational terms, the largest pre-engagement preparation the Blood Angels Chapter had conducted in its institutional history. The assembly was also, by Dante's own assessment that he articulated to Mephiston in the engagement's opening week, possibly insufficient. Mephiston did not contradict him.

The Hive Fleet Arrives

Leviathan's main mass translated into the Baal system in approximately the middle of 999.M41. The translation was not, in the Tyranid operational logic, a conventional warp-translation; Tyranid Hive Fleets did not use warp-travel in the way Imperial fleets did, but instead moved through realspace at sub-light speeds across decades and centuries, with the Hive Mind's coordination operating across the entire fleet through the Shadow in the Warp's psychic transmission. The Hive Fleet's arrival at Baal was, in operational terms, the culmination of a multi-decade approach that the Hive Mind had been calculating since long before the Imperium had identified Leviathan as a distinct fleet. The Hive Fleet's mass at arrival was, by the Imperial Navy's observational estimates, sufficient to physically occlude Baal's primary star — Baal-Sol, the system's parent star — from the surface of Baal proper. The occultation phase, in which Baal's surface lost direct sunlight as the Hive Fleet's biological mass interposed itself between the planet and the star, lasted approximately four months across the engagement's opening period.

The Hive Fleet's operational approach to the Baal system was the standard Tyranid pattern that the Imperium had documented across approximately fifty prior Hive Fleet engagements at smaller scales. The Hive Fleet's vanguard organisms — the smaller bioform-classes that the Hive Mind committed first in any engagement — descended onto Baal Primus in the engagement's first week, on Baal Secundus in the engagement's second week, and on Baal proper in the engagement's third week. The vanguard's operational purpose was not the immediate capture of the engaged worlds; it was the harvesting of biological mass — civilian populations, livestock, vegetation, every form of carbon-based life that the bioforms could process — into the Hive Fleet's continued growth. The vanguard wave was committed in numbers that the Imperial defensive forces could not stop at the bioform-by-bioform engagement level; the operational doctrine for Tyranid defence required engagement at the synaptic command level, where the destruction of Hive Tyrants and other synaptic-command bioforms could degrade the wider Hive Fleet's operational coordination across the bioforms the synaptic command was directing.

Dante's operational disposition for the engagement, established in the months preceding the Hive Fleet's arrival and refined across the engagement's opening weeks, was a layered defence that traded territory for time. Baal Primus and Baal Secundus would be defended in the engagement's opening phase by the Sanguinius-line Successor formations, with the operational expectation that both moons would eventually fall but that the defence would extract a substantial Tyranid casualty toll before the fall. Baal proper would be the engagement's consolidated defensive position, with the Fortress of Hera as the operational anchor; the Blood Angels' Chapter veterans, the Mephiston-commanded Librarius Conclave, and Dante's personal command formation would hold the Fortress against whatever the Hive Fleet committed to the engagement's final phase. The defensive disposition was, by Dante's own articulated reasoning, the only disposition that gave the engagement any operational possibility of being held until the Indomitus Crusade relief that Guilliman had committed to dispatching from the wider Imperial fleet. The defensive disposition would, in execution, cost the Successor formations the substantial fraction of their committed strength.

Baal Primus and Baal Secundus

The defence of Baal Primus and Baal Secundus across the engagement's opening eight weeks was the period in which the bulk of the Sanguinius-line Successor formations' casualties were sustained. The two moons, both irradiated death-worlds in their own right and both populated by approximately seventy thousand baseline humans each who had survived in shielded dome-cities across the post-Heresy millennia, were defended primarily by the Successor Chapters with limited Blood Angels reinforcement; the Blood Angels' main strength was being conserved for the Fortress of Hera engagement that Dante's disposition projected as the engagement's decisive phase. The moons were therefore the engagement's sacrifice zone, in operational vocabulary that the Successor Chapter Masters explicitly accepted in the pre-engagement planning conferences and that the engagement's execution validated.

The Lamenters held Baal Secundus's primary dome-city for approximately five weeks. The Chapter's pre-engagement strength of approximately four hundred Astartes was reduced, by the dome-city's eventual fall, to approximately one hundred and forty Astartes who extracted under Chapter Master Ramos's direction to Baal proper for the Fortress of Hera phase. The Flesh Tearers, holding Baal Primus's northern dome network, fought an engagement that Gabriel Seth's subsequent regimental account describes as the engagement that the Chapter's Red Thirst severity had been operationally engineered for; the Flesh Tearers committed approximately seven hundred Astartes to Baal Primus and extracted approximately two hundred to Baal proper after the moon's fall. The Knights of Blood, deployed to Baal Secundus's southern equatorial regions, fought engagements that the Imperial historical record holds in deliberate vagueness — the Knights of Blood's Excommunicate status meant the Inquisition did not formally permit detailed reporting of their operations — but the Knights of Blood's pre-engagement strength of approximately three hundred Astartes was reduced to approximately sixty by the moon's fall.

The Sanguinius-line casualties across the moons' defence reached approximately eight thousand Astartes by the engagement's tenth week — the largest single Astartes casualty figure that the Sanguinius gene-line had sustained in any engagement since the Heresy, and approximately a quarter of the total assembled strength. The casualty figures were communicated to Dante through the Chapter's vox-channels; Dante's response, articulated to the Chapter's command staff during the engagement's tenth week, was that the casualty figures were within the operational tolerance the defensive disposition had projected and that the Successor formations had purchased, through their casualties, the time the Fortress of Hera phase required. The articulation was, by Dante's subsequent admission, the most institutionally difficult statement he had made in his eleven hundred years of command. The articulation was also operationally correct. The Fortress of Hera phase would, with the time the moons' defence had purchased, be holdable.

Baal Primus and Baal Secundus, in the engagement's tenth week and the engagement's twelfth week respectively, were overrun. The Hive Fleet's bioforms physically occupied both moons across the following weeks; the dome-cities that had held the moons' civilian populations were comprehensively consumed; the Sanguinius-line Astartes who had not extracted to Baal proper in the operational extractions were killed in place. The moons' environmental conditions, in the engagement's subsequent months and in the years that followed, were degraded beyond the pre-engagement irradiated baseline by the Hive Fleet's biological occupation and by the subsequent partial extraction of the moons' biomass; both moons remain, in late-Indomitus Imperial cartographic notation, in worse environmental condition than they had been at the engagement's opening. The Sanguinius-line Astartes commemorate the dead on both moons through Chapter shrines that the Blood Angels have maintained on the moons' surfaces in the years following the engagement, with shrine-rotations conducted by Chapter veterans on operational pilgrimages that the Chapter has institutionalised as the Twin Moons Vigil.

The Fortress of Hera

The Fortress of Hera engagement, conducted across the engagement's twelfth through twentieth weeks, was the engagement's consolidated defensive phase and the period during which Dante's operational disposition was tested at the engagement's most intense intensity. The Fortress of Hera — the Blood Angels Chapter's monastery-citadel on Baal proper, constructed across the ten thousand years following the Heresy on architectural designs that traced back to Sanguinius's personal direction — was a defensive structure of extraordinary scale and engineering, with curtain walls extending approximately three kilometres around a central keep, with internal arcology systems that permitted the Chapter's full strength to operate from sealed interior positions without surface exposure, and with orbital defence platforms that the Chapter had been quietly upgrading across the preceding decade in preparation for the engagement that Dante had projected would eventually come.

The Hive Fleet's commitment to the Fortress of Hera engagement was correspondingly massive. The Hive Mind, by the engagement's twelfth week, had assessed the Fortress as the Imperial position whose reduction would complete the operational consumption of the Baal system; the Hive Fleet committed bioforms to the Fortress engagement in numbers that the Imperium's observation has subsequently estimated at approximately twenty billion organisms across the engagement's eight-week duration. The bioform mix included the standard Hive Fleet inventory of Hormagaunts, Termagants, Genestealers, Warriors, and Hive Tyrants, supplemented by the Norn-Queens that Leviathan committed only to the most operationally significant engagements and by the Bio-titan-class Hierophants that the Hive Fleet had been growing across the preceding decade for the engagements where the Hive Fleet projected requiring super-heavy biological assets.

The Blood Angels' defence of the Fortress, conducted under Dante's personal command from the Fortress's central command bunker, was the operational engagement that the Chapter's post-Heresy institutional preparation had been building toward across the ten thousand years since the Chapter's founding. The Death Company — the Chapter's Black-Rage-afflicted formation — was committed in successive waves to the Fortress's outer perimeter as the Hive Fleet's bioforms attempted breach operations; the Death Company's operational profile, characterised by combat aggressiveness uncoupled from conventional tactical caution, was the operational tool that the Chapter's doctrine had explicitly engineered for the engagement category the Fortress phase represented. The Death Company's casualties were, in operational terms, total — every Death Company Astartes committed to the Fortress engagement was killed in the engagement's execution — but the casualties were operationally acceptable because the Death Company's alternative was operational decommissioning rather than productive engagement.

Mephiston, the Chief Librarian of the Blood Angels and the Astartes commander whose name had been earned through the resolution of the Black Rage in his own Astartes physiology through means the Chapter has never publicly described, fought in the Fortress's engagement as the operational counter to the Hive Fleet's synaptic-command bioforms. The Hive Tyrants that the Hive Fleet committed to the Fortress engagement could not effectively engage Mephiston in psyker-level combat; Mephiston's personal psychic capability was approximately equivalent to a Hive Tyrant's synaptic-projection capability, and the Hive Mind's standard operational doctrine for engaging Imperial psyker-commanders did not adequately account for an Imperial psyker-commander of Mephiston's specific capability profile. Mephiston's engagement record across the Fortress phase included the personal destruction of approximately fourteen Hive Tyrants and three Norn-Queens — engagement counts that the Chapter's subsequent historical record treats as the Chapter's most operationally significant psyker engagement in its institutional history.

The Fortress held. The Sanguinius-line Astartes within the Fortress, by the engagement's eighteenth week, had been reduced to approximately twelve thousand Astartes from the engagement's opening twenty-two thousand. The Hive Fleet's commitment to the engagement had not abated. The Fortress was, by Dante's articulated assessment to his command staff during the engagement's nineteenth week, approximately two weeks from operational collapse if no relief arrived. The Indomitus Crusade relief that Dante had been calling for since the engagement's opening was, by the Imperial Navy's in-system intelligence, in approach but had not yet arrived.

My sons are still standing. They will be standing when the relief arrives. I do not promise more.

— Commander Dante, recorded on the Fortress of Hera command vox during the engagement's nineteenth week — the recording was preserved in the Chapter's post-engagement archive and has been formally adopted by the Blood Angels as the Devastation Anthem, recited annually on the engagement's anniversary

The Indomitus Relief

For twenty agonizing weeks, the Fortress of Hera on Baal withstood the apocalyptic fury of Hive Fleet Leviathan. Commander Dante directed the desperate final stand of the Blood Angels and their successor chapters, watching centuries of noble heritage being ground into the crimson dust. The defenders were pushed to the absolute brink of extinction, out of ammunition and fighting blade-to-claw over the shattered ramparts. Just as the synaptic shadow threatened to crush the last vestiges of resistance, the heavens tore open. Roboute Guilliman's Indomitus Crusade relief fleet broke warp-transit in the system's outer edges, unleashing a storm of righteous retribution upon the xenos swarm.

The scale of the counter-attack was staggering. Guilliman had brought nearly forty thousand newly forged Primaris Astartes, marking the first large-scale integration of Cawl's creations with the Firstborn lineage. Imperial Navy capital ships immediately prioritized the Hive Fleet's synaptic-command vessels, obliterating three massive Norn-Queens within the first six days of combat. This precise orbital decapitation severely weakened the Hive Mind's local grip, causing the Tyranid ground swarms to lose their terrifying, unified coordination. Unrelenting lance batteries turned the desert night into blazing day.

Exploiting the sudden disarray, thousands of Primaris drop-pods slammed directly into the courtyards of the Fortress of Hera. The towering newcomers seamlessly integrated with their battered, blood-soaked brethren, pushing the tyranid beasts back from the inner sanctums. Within a mere ten days, the Fortress achieved defensive stability. Faced with insurmountable casualties and a severed command structure, Leviathan broke orbit between the eighteenth and twenty-fourth weeks, drifting off to seek easier prey in the Segmentum Ultima. Baal was saved, though dangerous splinter fleets would haunt the sector for years to come.

Aftermath

Baal survived. The Sanguinius gene-line survived. The cost, by the engagement's formal close in early 999.M41, was the loss of approximately twelve thousand Sanguinius-line Astartes — about forty percent of the assembled strength — and the operational degradation of substantially every Sanguinius-line Successor Chapter to recovery timelines that the Imperium's subsequent operational planning has projected as multi-generational. The Lamenters were reduced to approximately one hundred and forty operational Astartes by the engagement's close, were further reduced through subsequent engagements in the Indomitus Crusade's opening years, and were, by the Indomitus Crusade's second decade, listed as operationally unrecoverable. The Knights of Blood's surviving Astartes were absorbed into the Blood Angels Chapter on terms that the Inquisition formally accepted without lifting the underlying Excommunication. The Flesh Tearers, the Angels Encarmine, the Angels Sanguine, and the wider Successor formations returned to their Chapter monasteries in degraded operational states from which the late-Indomitus period's subsequent engagements have not permitted recovery.

Dante's subsequent operational appointment, conducted by Roboute Guilliman in the months following the engagement's close, was as Lord Commander of Imperium Nihilus — the Imperial sub-imperium that the Cicatrix Maledictum had operationally isolated from Imperium Sanctus across the galactic plane. The appointment was, by Guilliman's articulated reasoning, the Imperium's recognition that Dante's operational capability and personal authority were the only assets the Imperium had available that could plausibly hold Imperium Nihilus together against the operational pressures the sub-imperium was facing; the appointment was, by Dante's subsequent admission in private correspondence with Mephiston, an operational responsibility he did not want and that he accepted because the Imperium's situation required it. Dante held the Lord Commander appointment across the subsequent years of the Indomitus Crusade and continues to hold it in the late-Indomitus period. His operational authority across Imperium Nihilus is, in late-Indomitus Imperial terms, comparable to the operational authority that the Warmaster appointments of the pre-Heresy period had carried — an institutional concentration of authority that the Codex Astartes had been engineered to prevent and that Guilliman's appointment of Dante explicitly required the Codex's formal suspension to permit.

The Blood Angels Chapter's post-Devastation institutional character was, in the years following the engagement, substantially transformed by the Primaris-integration operations that the Indomitus Crusade's relief had initiated. The Chapter's pre-engagement strength of approximately one thousand Astartes had been reduced, by the engagement's close, to approximately three hundred Firstborn Astartes; the Primaris reinforcement of approximately one thousand Primaris Astartes that the Indomitus Crusade had committed to Baal's Chapter restoration brought the Chapter's combined strength to approximately thirteen hundred Astartes by the engagement's second year. The integration was, by the Blood Angels' subsequent institutional assessment, the most operationally significant institutional change the Chapter had undergone since the post-Heresy reorganisation. The Chapter's contemporary operational character — a Firstborn-Primaris composite formation operating under continued Sanguinius-line traditions but with Primaris doctrinal adaptations that the Firstborn elements have institutionally accepted — is the post-Devastation institutional product that the Indomitus Crusade's wider Chapter-restoration operations have been replicating in degraded form across the Indomitus Era.

The Devastation's cultural memory in the wider Imperium is, in late-Indomitus terms, the Imperial canonical example of what the Indomitus Era requires Imperial defensive engagements to accomplish: the holding of an Imperial position against a Tyranid engagement of overwhelming scale, the integration of relief operations under the operational urgency that the engagement's scale demands, the institutional acceptance of casualty figures that pre-Indomitus Imperial doctrine would have judged operationally unacceptable. The engagement is, in late-Indomitus Imperial military instruction, the engagement that Astartes Chapter officers are required to have studied as part of the Codex-revised operational doctrine that Guilliman drafted in the engagement's aftermath. The engagement is also, by the Blood Angels' own institutional reckoning, the engagement that demonstrated the Sanguinius gene-line's continued operational character to the wider Imperium at a moment when the late-millennium Imperial institutional consensus had been quietly assessing whether the Sanguinius gene-line's Red Thirst severity made the line's continued operational viability sustainable. The engagement's answer to the assessment was unambiguous. The Sanguinius gene-line was operationally viable. The line was also, by the engagement's close, substantially reduced.

The shrines on Baal Primus and Baal Secundus, maintained by the Chapter through the Twin Moons Vigil, hold the names of the Sanguinius-line Astartes killed on the moons during the engagement's opening phase. The names number approximately eight thousand. The Vigil rotations walk the shrines once a year, on the engagement's anniversary, in formation. They walk them in silence. The bells of the Fortress of Hera — recreated in the engagement's aftermath from the pre-Devastation designs that the engagement's damage had destroyed — ring once a year on the engagement's anniversary. They have not been silent.

You have held the line. You have held the bloodline. The Imperium owes you what it cannot pay. Accept what I can give: the burden of Nihilus, and the silence between us.
