Tirr Volan from the house of Direnni, one of the most powerful magicians of the Underdark, fleeing from his enemies, uses the last resort: a spell that allows him to cross the line separating the worlds from each other. Tirr finds himself in a strange world where magic is unknown, in a country inhabited only by people who have never seen the dark elves of Ilithiiri, in an abnormal city with the unpronounceable name Sankh... Sankh... St. Petersburg. But that's not so bad. The trouble is that, without knowing it, Tirr found himself drawn into a dark story from the first minutes... However, who, if not a magician from the dark world, can cope with the most unexpected situations...
