The Death Mask of Sanguinius

The Recovery

Sanguinius's body was recovered from the Final Chamber of the Vengeful Spirit by Dorn within hours of the Emperor's wounding. The body had been laid down by Horus in the centre of the chamber — not discarded, but arranged. Dorn lifted it himself, carried it down to the loyalist staging area, and did not let anyone else touch it until the Sanguinary Guard arrived to receive their primarch. He did not speak during the carry. His sons later said it was the only time they ever saw him weep.

What survives of Sanguinius's body — beyond what the Blood Angels later interred at Baal — is the mask. It was cast on Terra in the days between the Siege's end and the Scouring's opening, before the long journey home.

The Casting

The casting was supervised by Azkaellon, Sanguinius's Chief Sanguinary Guard, the last surviving member of the primarch's personal detail. Azkaellon insisted that no Mechanicus tech-priest touch the body. The mould was made by hand, using a clay paste prepared by the Chapter's own Apothecaries from materials Azkaellon had brought from Baal for ceremonial use. The casting itself, when poured, was an alloy combining Baalite iron, gold from the Imperial Palace, and trace amounts of the metal recovered from Sanguinius's own armour at the moment of his death.

The finished mask preserves the exact likeness of the primarch in the moment of his death — peaceful, beautiful, sorrowful. The features are not idealised. The slight asymmetry of the mouth and the half-closed left eye are reproduced precisely. The mask is small enough to fit a Chapter Master's face. It is large enough to remind anyone who looks on it of what the primarchs actually were.

We did not seal him in stone. We sealed his face in gold, and we gave it to his sons.

— Azkaellon, attributed to the casting

The First Wearer

Azkaellon was the first to wear the mask. He wore it for less than a Terran year. The Sanguinary Guard who served alongside him during that year recorded their observations of his bearing afterward; the records were preserved in the Blood Angels' archive on Baal and later partially leaked into the wider Imperial historiography by Dante in M41. Azkaellon, the records say, became quieter. He did not refer to the mask by name. He gave orders through it. When he removed it at the end of the year — to die, by his own arrangement, in a fortification engagement at the close of the Scouring — he handed it to the man who would become the Blood Angels' first official Chapter Master.

That man, whose name the Chapter has preserved but does not speak aloud, wore it for the next ninety years. After him, the chain has been unbroken.

The Wearing

Each Blood Angels Chapter Master wears the mask. The wearing is not ceremonial — he wears it into battle, into council, into the long centuries of administering Baal. Putting it on is, in Blood Angels theology, to remember Sanguinius's death as if it were one's own. To wear it for a century is to have a kind of access to him that no other Astartes commander has. To wear it longer is to find that the access begins to flow the other way, in ways the Chapter does not speak about in front of outsiders.

Most Chapter Masters wear it for fifty to a hundred years before death takes them — usually in battle, usually defending a position they could have withdrawn from. The mask survives them. It is recovered from the field by the Sanguinary Guard, cleaned, and held in the Chapter's reliquary until the next Master is named. The next wearer puts it on at his elevation. The transition is not, by any reliable account, a comfortable one.

The Sight

Wearers report seeing things while the mask is on. The reports are consistent enough across centuries that the Chapter's Sanguinary Priests treat them as a known psychic phenomenon rather than as individual aberration. The most common report is the Final Chamber — wearers experience, periodically, brief instants of being Sanguinius in the moment of his death. Hesitation, recognition, the blow that does not come. These instants are not described as memories. They are described as present-tense.

Less common reports include glimpses of an unmarked future, voices that may be Sanguinius's, and what one Chapter Master described, in a private confession to a Sanguinary Priest, as "permission." What permission, the Chapter Master would not say. He died in engagement the following decade and the mask passed on.

I have worn this mask longer than any of my brothers. It has become my face.

— Dante, attributed late M41

Dante's Centuries

Dante has worn the mask for over a thousand years. By chapter measure he is the longest-tenured Chapter Master of the Blood Angels by an order of magnitude — and across an Imperium that has had its share of long-lived warriors, the longest-tenured commander of any Loyalist Chapter, by far. Whether his refusal to die is rejuvenation, willpower, the mask's working, or the simple fact that he has not yet found a battle he was willing to lose, is not known outside Baal.

The mask shows no wear. The man beneath it, by quiet Chapter observation, has shown some — but not in the ways a Chapter Master of normal tenure would show wear. He sleeps less. He speaks less. He has, the Sanguinary Priests note in confidential records, begun referring to events of M31 in the first person without apparent awareness that he is doing so. The Chapter does not correct him.

The Succession

Dante has named no successor. The senior Captains of the Blood Angels — Mephiston, Astorath, Tycho before his transformation, several others — would be obvious candidates. None has been formally elevated to wear the mask. Whether this is because Dante refuses to yield it, because none of them is judged ready, or because Sanguinius himself (through the mask, in some readings) has not selected, is open and is not discussed even within the Chapter outside of the Sanguinary Priests' restricted councils.

The Chapter's working assumption, never stated aloud, is that the mask will choose. When Dante dies — if Dante dies in a way that returns the mask to the Chapter's possession — the next Master will be the one the mask permits to put it on. Whether such permission can be refused, on either side of the casting, is a question the Blood Angels have not had to answer in a thousand years.
