The Hollow Hills near Yorkshire have their own mysterious life in full swing. The young Slovenian Vratko, who finds himself there, must pay for his help and hospitality. Warlock from Gardariki must find the item needed for the mysterious Ritual. It is not difficult to get into the cave labyrinth under the ruins of Strineshalch Abbey, where the enchanted tripod is kept. It’s hard to get out of there alive, leaving the Horror of the Depths with your nose. We have to rely on prayer and... the help of werewolves. And ahead is the battlefield of Hastings. Will sorcery help drive away the hated Normans, or is England destined to be conquered?
