History
Using Karnilla's magic, Loki broke the enchantment upon Mjolnir and stole it from his brother. Loki used the hammer to kill Thor, Sif, Balder, and Karnilla herself, then called upon Jormungand and the rest of Odin's enemies to attack Asgard together. The devastation was immense, and the gods of Asgard were slain, but Surtur claimed that he was destined to bring forth the Ragnarok and killed Loki. The Midgard Serpent said that it would sooner kill Surtur than burn, and Surtur beheaded it with his Twilight Sword.[1]
