the first book in the “Chronicles of Riv and Ninna” cycle. The story takes place one and a half thousand years after the invasion of demons. In the dimension where six races live side by side on a single planet: Elf, Orc, Human, Tul, Dwarf, and Argu. All races are technically advanced but do not possess magic. The demons invade the dimension and destroy the space colonies of all six races. They drive the remnants of their forces onto the earth.
After several large-scale battles, the magical warriors of Hell and the demons subjugate the world and set about destroying the survivors—souls are sent to Hell. Some of those who fought particularly well against them are turned into servants, having their personalities destroyed while their souls remain intact. Those who manage to hide during the Wars are then finished off.
