Warhammer 40k Codex: Adeptus Custodes
The Adeptus Custodes are the Emperor’s personal guard. For ten thousand years they have stood sentinel over the Master of Mankind and defended the gates of his palace. Yet now the Emperor’s blades are unsheathed. Biochemically fashioned from infancy to function as supreme tacticians, combatants and bodyguards, they are death incarnate to those who oppose the Emperor’s will. Each Custodian is sublimely skilled, their talents and abilities to the Space Marines what those transhuman warriors are to unaugmented Imperial soldiery. The Ten Thousand walk the stars in numbers not seen since the Great Crusade, and woe betide those who stand in their way.
