Let's face this game is rough, and your character is probably going to die. At least at some point. That's okay because characters in this world die all the time.
Resurrection magic is deeply embedded in the Linder fabric of space and matter. Consciousness never actually dies as it is made of light, and thus exists its host, the body at 'death.'
That is why souls travel all about everyone all the time, as planes and dimensions all share the exact same space-time as we know it. Dimensions and entities overlap and travel all throughout each other.
