Sylvan Sjenoviki of Rodnovery.
There is tale of a type of creature in Slavic folklore who rules the forests. His name is Leshy, he also has a wife, Leshachikha, and children, Leshonki. The forests are their homes and they take great pride in their work. They are often associated with bears and wolves (like the Volkhvi) and they can be more or less friendly depending on various factors, such as your communities relationships with the forest. A good offering to give to your local Leshy and his family, is some salted bread on a naturally occurring tree stump.
They tend to behave like mishevious faries and those who enter their forests without an offering of respect will find themselves hopelessly lost.
If you see them, which is rare, they will be as tall as the tallest tree in their forests. But otherwise, Leshy are transformed into animals, usually bears and wolves.
It is said that if you bring a leaf with you, you will fall under the same supernatural protection as the rest of the forest. Cover it in wax so that the protective powers of your token from the forest won’t fade with time.
