Domovoy, the Sjenovik of the House in Rodnovery.
The earliest tradition of the Domovoy has it processing the form of a snake, specifically a white snake with a crown. In the same way that a snake gets rid of mice and increases the health and wealth of a house, so too does the Domovoy protect his house. Later on, he came to the become humanoid, commonly a man, but sometimes a woman, and resembled the master, or the mistress, of the house. Domovoy are invisible, to see one is a bad omen, it means that the head of the family is going to die soon.
Like the Dolya, Nedolya, and Kikimora; the Domovoy lives underneath the stove. It was common to give your leftovers to the Domovoy. A happy Domovoy is a good Domovoy, they’ll help out with chores, put wood into the fire during the night and look after your herds. An unhappy Domovoy is a bad Domovoy, it’s activities are very similar to a poltergeist. Families that fight all the time anger the Domovoy most and if it continues on, he will leave entirely, leaving the family and house completely unprotected.
If you want a Domovoy there’s an Ancient Slavic ritual to do so. Dress up in your finest clothes and walk around a local park while saying, “Deduska (Grandfather) Domovoy, come and live with us and tend our home.” This ritual may need to be repeated multiple times. But when it works, make sure to run a bath at least once a week and put his food by the stove every night.
Slava Bogum!
