Xiphos (Battle Barge)
From Warhammer 40k - Lexicanum
The Xiphos is a Battle Barge in service with the Cruor Blades Chapter; it is also the flagship of the Chapter's fleet. Numerous relic weapons adorn the Xiphos' walls, which were once wielded by highly esteemed members of the Cruor Blades, who have died serving the Chapter.[1]
Under the command of Chapter Master Cyras Vitalion, the Xiphos led the Cruor Blades' fleet to aid Baal before it was invaded by Tyranids. The Chapter, however, arrived too late and only reached Baal after the Blood Angels and their allies had defeated the Tyranids. The Cruor Blades, though, are now among the Imperial forces aiding the Blood Angels in the Angel's Halo campaign.[1]
