Mythos Angelica Mortis

The Mythos Angelica Mortis is a tome of ancient knowledge listing the fraternity of twenty Space Marine Chapters, collectively called the Astartes Praeses, which had been created for the sole purpose of guarding against incursions from within the Eye of Terror following the Great Scouring. In the current 41st Millennium, there are eighteen. The Archenemy had annihilated one Chapter and, more shocking still, another had been branded Excommunicate Traitoris.

Though no comprehensive list has ever been assembled, the current known members of the Astartes Praeses include the:


 * Brothers Penitent
 * Crimson Scythes
 * Excoriators
 * Iron Talons
 * Knights Unyielding
 * Marines Exemplar
 * Night Watch
 * Reclaimers
 * Relictors (declared Excommunicate Traitoris)
 * Sons of Malice (declared Excommunicate Traitoris)
 * Subjugators
 * White Consuls
