Skabscrath in Warhammer: Dark Omen.[3]
The legendary blade of the Undead mercenary Ennio Mordini, Skabscrath flickers with pale flame. A blade so potent it cannot be sheathed without first taking a life, Skabscrath is possessed of an evil sentience that drives the wielder to ever darker acts. Some claim the blade is more steeped in evil than any Vampire, for it will betray its wielder if its bloodlust is not sated. When unsheathed, Skabscrath continually emits the terrible screams of all those it has slain, amplified to such a degree that it can cause those who hear them to die of fright.[1a][2a]
