The friends left the Land of the Elves, where Lisil's mother was freed from captivity, and now their path lies overseas. Accompanied by the Anmaglahk elves Sgayl and Osha, they follow to a snowy castle in the mountains, where an artifact is kept that may be able to protect against the Great Enemy. Or, conversely, to bring his coming closer. In any case, as the travelers believe, it is better to transfer the mysterious luminous ball to the care of scientists from the Guardian Guild. The path would be long and difficult in itself, but what makes it deadly dangerous are its pursuers: Sgayl’s fellow Anmaglahk caste, who are ordered to kill the dhampir, and the tireless Velstil Massing, Magier's half-brother, a vampire and sorcerer, eager to get his hands on a magic ball that bestows power unknown to mortals.
