This story about the civilization of Eo was told to me by the old rat Zorgo. Once upon a time, each eo shared joy and pain with its people. The meaning of their life was the quiet happiness of unity. But experiments on nature led to the fact that the eo moved away from each other. Controversies divided the people of Eo into warring clans. The rats, the last warriors of the city of Protto, came to help. Those for whom death is a continuation of life.
