Biography
Thor entered Hel after being falsely led by Loki to believe that Sif had died from an attack by a Rock Troll. Hela disguised herself as Sif and lured him into a trap. The two battled and Thor defeated Hela. She revealed that Sif had never reached Hel. Thor questioned her about Sif's possible whereabouts, and she suggested that Sif might be in the Cave of Ages on Niflheim, telling him that she had seen the dead end up there before. Thor did not believe her, but had no choice but to follow her lead, though he warned her that if it was a trick it would not be the last she saw of him. Once he left, Hela remarked that she planned on it.
