Loki, the eponymous God of Mischief trickster magician archetype in every one of his multiverse variants, also ends up being the only one to breach AND catastrophically affect the literal fabric of time & reality itself, because?-- he is fundamentally one of the most powerful beings in the entire canon multiverse.
The Spiderwick chronicles just gave me whiplash of that phase I had as a kid where I adored any and all fiction where you stayed at a magical house and you can study them to your hearts content.
Or you stayed in a house in the middle of a fantastical place.
