Did the ordinary geologist Nikita Sokolov think that when he went to explore the next working site, he would find himself in a world that once became a refuge for the races that once inhabited the Earth: werewolves, brownies, forest spirits? Fleeing from the fires of the Inquisition, the gnomes built Labyrinths leading to The new Erin is a new world for those who wanted a free life and a free faith. They closed the passages, handing the Key to the Perfect - people who consciously renounced murder.

And today, more than seven hundred years later, in order to return home, Nikita Sokolov will have to find both.
