Loki arrives in a hidden realm/plane/place, where tricksters of all pantheons have a home, and goes off to do some healing (of someone else).
Coyote accompanies Thor to the realm/plane/place, and tries to talk sense to him, but not happening, Thor is thick as a brick!
I think Hades was there and Thor insulted him. Also, Narfi and Vali were playing/arguing nearby, and when Thor saw them, he got really angry and declared they need to be put to death - he had thought they had been killed at birth!
Anyone recognize this story?
