In my campaigns where you go when you die isn't alignment dependant. Instead it matters a great deal what pantheon controls the region.
So for example, if you die within the borders of my Roman Empire you'll end up in Hades.

I have it on good authority.
That seems to cause some problems, like if a Viking raider goes off and raids another country, dying in battle, he ends up in that country's afterlife instead of Valhalla? Seems that would upset Odin, he needs those warriors for Ragnarok!
