Wars of the Black Alliance
Ragnar the Black
Ragnar the Black was an evil necromancer from ancient times.
Ragnar used his undead armies to conquer the Old World, crushing all who stood before him. Fortunately, just when everything seemed lost, Ragnar was slain in his castle by a heroic champion armed with the blessed sword Ragnarbane. Ragnar was entombed in the Mountain of Sorrow where he rested undisturbed for a millennia, until agents of the Dark Cabal unearthed him.
It is said that they took the Amulet of Undying and brought it to Black Harbor.
