The Wulfen Stone
From Warhammer 40k - Lexicanum
The Wulfen Stone is an ancient[1] and large russet diamond[2] that is among the Space Wolves' greatest treasures.[1]
It was forged by the Iron Priest Fengri to house the raging spirit of the Wulfen, and it is carried to battle only in the most extreme circumstances. In the Stone's presence, the caged, bestial nature deep within the sons of Russ is set free, filling them with violent and uncontrollable rage.[2]
