Frostmourne, Variant (5e Equipment)
From D&D Wiki
Weapon (longsword), Legendary (requires attunement)
Frostmourne is a fearsome, rune-inscribed two-handed longsword of the Lich King. The runeblade originally belonged to Ner'zhul, who thrust it from the Frozen Throne, waiting for an adventurer to discover it. Upon attuning to the blade the wielder, the hope was that they would become possessed by the lich king and lose their soul to the blade's eternal hunger. They would become a pawn of the sealed lich, allowing him to enact his horrid ways through them. The runes on the blade say "Soul devourer - The Cursed Blade of the Legion."
