Yes, a bit of a complicated topic. I am curious, though, as to how different polytheist traditions view "the soul." Was/is the soul considered a single thing, whole unto itself? Or multi-part? If so, what are the different parts? Are there different destinations for each part?
I actually have a theory, so to speak, that I'm working on to help me understand the nature of the soul in connection to the Gods, Nature, Animism and many other things. It's still in the early stages and hard to explain, but one of the most basic components is the idea of at least 3 (well, almost 3.5) components to a being. The outer body (which is infused with energy and not just isolated, and which I simplify with calling it the Green); the middle core which consists of 2 parts (I call this the White) which are the center of the core and then the outer shell, with our own personal energy and the energy of our interactions with others that goes beyond the level of the Green; and the center line (the Red) which is essentially the direct connection we have spiritually to every other being and body in the universe and existence, from the smallest specks to the Gods themselves.
So, I know that probably sounded like rambling. It gets a lot more complex and full fledged if I go deeper into it, but it's really hard to do so on the fly. This is all me just trying to make sense of everything, and my mind sometimes makes crazy circles!
