Malekith the Accursed ruled the Dark Elves of
Svartalfheim. Svartalfheim is one of the nine worlds of Asgard. Malekith mastered sorcery, making him a formidable ally to the other enemies of Asgard. He formed an alliance with the god of mischief
Loki on behalf of
Surtur. Not long after that agreement, he used a special food provided to him by
Hela. The food contained some sort of magic, which gave him control of the humans of
Earth. While continuing his quest, he took the life of Eric Willis, guardian of the
Cask of Ancient Winter. Before his death Willis conveyed the cask's location to Loki. Not willing to give up his quest, Malekith Kidnapped the Asgardian
Lorelei in order to gain control of the god of Thunder.
Thor discovered that he had been tricked into falling for a stack of wood, and became enraged as he learned that the real Lorelei was being held captive by Malekith. Lorelei was eventually freed but, Thor was forced to battle
Algrim the Strong. Malekith attempted to destroy both combatants by plunging them into a pit of molten magma; subsequently Malekith retrieved the Cask of Ancient Winter, from the being known as
Jagrfelm. Shortly after Jagrfelm's death, Malekith released its power upon Asgard in his quest to rule all nine worlds.
