For all the time he'd spent feeling as though he didn't fit there, and the later years he'd spent outright hating the place, it had been a strange blend of satisfaction and shock to bring about its prophesied downfall and watch it stabbed through to its very heart.

"We had a sister," Loki says quietly, picking up a discarded twist of wire and drawing it through his fingers. "Hela. Goddess of death, locked away before Thor was born, never to be spoken of again, until Odin's death." So, yes, that also happened. "And if you thought I..." He laughs, shaking his head.

Its prophesied end, Ragnarok, the sword of Surtur drove through the heart of the planet. It is not lost. It is dust, and Hela with it."
