Ive always had it depend on the character, for example my wraith had a amulet of a black sun that would return him to the abyss, for my humans I've generally just pretended it was a carriage, etc. 

yes

the fact that they're called "soulstones" and not "/warp" means they're things IRP

but that doesn't mean i dont usually find other IRP explanations first if they're easier. i just think soulstones are things IRP and can be cited IRP if push comes to shove
