In Elric of Melniboné, Elric and Yyrkoon find the runeblades in a realm of Limbo and commence battle. Elric and Stormbringer disarm Yyrkoon, and Mournblade disappears. Yyrkoon is defeated, and Elric and his cousin return to Imrryr. In The Weird of the White Wolf, Elric returns to Imrryr after a long journey and confronts Yyrkoon, who usurped the throne in his absence. Yyrkoon has regained Mournblade through unknown means and uses it to attack. Elric and Stormbringer kill Yyrkoon, and no further mention is made of Mournblade. All of Imrryr is destroyed by invading forces, so it seems that Mournblade shares the city's fate. In Stormbringer, Elric learns that the representatives of Fate, which serve neither Chaos or Law, recovered Mournblade from the netherworld. They present it to Elric and explain that the runeblades were designed to be wielded by those with Melnibonéan royal blood as a check against the might of the Dead Gods of Chaos. Elric gives Mournblade to his kinsman, Dyvim Slorm, and the two men become embroiled in a confrontation between the gods. In Roman Catholic theology, limbo describes the temporary status of the souls of good persons who died before the resurrection of Jesus, and the permanent status of the unbaptised who die in infancy (without having committed any personal sins, but without having been freed from original sin). ...

• Mournblade(as Mourneblade) is featured in Konami's video game Castlevania: Symphony of the Night and possesses the ability to heal the player character whenever he strikes something with it(much like how Mournblade and Stormbringer grant their wielder health and vitality when used to slay a foe, though the game weapon can grant health even when striking non-living objects, such as candles). Mourneblade is widely regarded as one of the best weapons in the game, and is considered a "rare" weapon.
