Calix Cruentes
From Warhammer 40k - Lexicanum
The Calix Cruentes is a jeweled cup, fashioned from a human skull, that is a relic of the Blood Drinkers Chapter. It is kept by the Chapter's Chaplains and only those Battle Brothers who are succumbing to their gene-seed's flaws lay eyes upon it. The Cruentes is filled with blood, and drinking from it helps the afflicted keep the visions away for a short time; allowing the Battle Brother to decide if he will join the Death Company or receive the Emperor's Mercy.[1]
