Hi!
I'm running a Planescape campaign.
One of my friends plays a CE torilian drow follower of Vhaeraun. He has lived in the outlands for 3 years.
In the last session he was killed during a battle on Avernus, the 1st layer of Baator. He is not properly a faithful guy....
I'm wondering what should happen to his soul. I mean, are torilian elves submitted to Kelemvorn judgement? Vhaeraun is not a power of the torilian pantheon (Lolth is but her son isn't if I remember well).
Are all the souls of those mortals that were born on Toril examinated by Kelemvor? Even if they die outside the realmspace and are followers of gods that do not belong to his pantheon?
Hm. Well - ok - from the top I'd say the first thing s far as I know there's no official canon answer on this. So there's nothing we can point to and say "It says here that..."
So if I were presented with this situation in my own game?
First, I would have to ask myself if I'm running a Planescape game or a Forgotten Realms game. That'll decide if Kelemvor gets involved in this as a judge automatically or not.
Second I would ask, "Which way is more fun for the players?" If one way is just sorta meh when it comes to getting the character raised and the other lends itself to plothooks galore - I know which one I'm picking. I assume that's why you're asking, you're looking for plot stuff right? Otherwise if the players were never going to find out In Character where he went I would suggest saving your efforts for things that will actually come Up in play.
