The Omnis Arcanum is the battle barge that serves as the mobile fortress-monastery of the Blood Ravens Space Marine Chapter. The Blood Ravens Chapter has no official homeworld in the 41st Millennium, having lost their original fortress-monastery of Selenon when their Chapter planet of Aurelia was swallowed by a Warp storm. Instead, their fortress-monastery is currently situated aboard the battle barge Omnis Arcanum. The rest of the Chapter serves aboard the large Chapter fleet of strike cruisers and battle barges.
The Blood Ravens' famed Librarium Sanctorum is maintained deep within the heart of the Omnis Arcanum. This is where the Chapter keeps its records of heroic deeds, lore of vanquished enemies and captured heretical knowledge. It is said that the Blood Ravens Librarium upon the battle barge is one of the largest repositories of information in the Imperium outside of the archives of the Inquisition itself.
