Bibliotheca Imperialis

Capitula

The thousand-strong Astartes chapters that succeeded the original twenty Legions after Guilliman's Codex Astartes broke the primarchs' commands into smaller institutional units. Some descend directly from a primarch's gene-line; others trace lineage to successor foundings or to gene-seeds the Mechanicus has been unable to fully classify. Loyalist chapters and the traitor legions of the post-Heresy era are catalogued together; their genealogy is the same.
