Ashes of Civilization

A civilization has developed from caring for hair and drinking blood to fighting in the sky, and even started the interstellar era.

However, the higher the technology tree, the faster the destruction, leaving only the ashes of civilization. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
