“This is the sword Nightbringer. Once it served Orcus, but now it seeks vengeance against the Lord of the Undead.”
Each of the lesser courtiers of Orcus, the first exarchs he forged in his great battles against the gods, received one mighty artifact. The Lord of Zombies received Nightbringer, a weapon supposedly forged from a single drop of blood shed by the Chained God when he cut himself on the mote of absolute evil that formed the Abyss.
