Mythic Russia: Motherland Reborn
Tengrism: A turkish shamanistic tradition. Originates from Mongolian and turkish traditions, apparently? Reveres Tengri as the omnipotent sky god (yayyyy).

Burkhanism: A more pantheistic version of Tengrism, basically? However, rejects ties to the demonistic spirits
