Dozens of clans of forest dwellers live on unknown land. Each of them is like a family of hundreds of people - all its members have their own place and business. They believe in the Great All-Father and follow his precepts. "Tverdislavici" is one such clan. Their main wizard, Jeyana Furious, has the gift of collecting all the magical power of relatives together and hitting enemies with it. And this force will be very useful to her, because the witches of Snake Hill, who periodically attack settlements, lead forest evil spirits.
