Prince Rau, a young talented commander of an almost annihilated people of snow elves, wants to take revenge on his enemies.

Yet the amulet scattered the prince’s supporters to different places, and he himself—wounded—found himself alone on Earth. What awaits him in the world of a techno-civilization?
