Literally every character in the history of the show is fair game now if they go there. Henry Sr., Huntsman, Daniel, the villains, James. They could really go places with an Underworld arc. Especially if they introduce Hades and Persephone as well as some new "undead" characters in the Underworld. I don't know about them being Elysium Fields....

That is a very restricted place: even a single impure thought disqualifies you for going there.

Ingrid killed her sister. And she wanted to get everyone killed with the Spell of Shattered Sight
