Spirit plane
The spirit plane and the material plane are closely related, yet very different. The spirit plane, for instance, has no strict topography. The most popular analogy among those who traveled there is "swimming in a constantly stirring soup", eve though some spirits, mostly elemental, seem to hold their ground. As in our world the inhabitants of the spirit plane are numerous and versatile. There are no strict rules when it comes to spirits, but we can try and sort them into these four categories.
ghosts
life spirits
elemental spirits
folken spirits
