So in my campaign a character died in a way where the body is entirely destroyed, but the players wanted to revive them anyway. The only spell that they can possibly access can fix this for them is true resurrection which is way out of range for them. The backup plan was to go find their soul and figure out a new plan from there. I’m fine with that with my understanding of what happens when you die in Forgotten Realms lore (as follows)
Step 1. You die.
Step 2. You go to the fugue plane and get judged by Kelemvor.
Step 3. Your soul is sent to whoever has a claim to it in cases of warlockery, religious beliefs or other deals.
Step 3a. In case the above doesn’t apply your soul gets sent to it’s alignments plane.
Step 4. You either become a native being of the plane (lesser devil, demon, planetar, etc) or are a spirit that resembles your original body.
This character was chaotic good, meaning they’re in Arborea/Olympus. My players are on a crash course to getting into that plane and finding this character, but Olympus is a plane of heroes and has lots of things to fight, what happens if this character dies? Do they get rejudged and just end up where they are again? Are my assumptions wrong and I’m missing something?
My take is, it is your game. You could say the groups desire to return the player to life has caused their soul to be stuck in limbo whole they are looking for it, or send it to where ever they are going. If you want them to succeed then breadcrumb them to it. If you do not want them to succeed turn it into something big and nasty with a vengeance for them not saving the player.
