阿布哈茲人
In the eastern Baltic region of Livonia, people designated as werewolves went underground in the shape of dogs to fight against sorcerers who stole the shoots of the grain. If the werewolves failed to wrest the shoots, there would be famine. In Romania, "strigoi" were people born with a caul, which they donned upon reaching adulthood; this made them invisible. They then travelled in animal form to the meadow at the end of the world. There they fought each other all night, becoming reconciled in the morning. The reason for the fight is not specified. The Circassians told that, on a certain night of the year, their sorcerers fought with the sorcerers of the Abkhaz people, trying to suck each other's blood.
