As far as races that can be called a "species", these are the ones with defined names and champion representatives: - Humans - Minotaurs - Trolls - Yordles - Vastaya - Brackern - Yetis - Dragons After this things get more awkward cuz things are way less clear cut

"Spirit" and "Demon" aren't races but broad classification systems. Spirit is just any kind of entity that originates from the Spirit Realm, and so yordles are a species of spirit Demons are also kinds of spirit, but a broad group of predatory beings that aren't defined as a species
