Civilization Number 137

Civilization Number 137 is one of the numbered civilizations of Three Body, the virtual reality game encountered by the nanomaterials researcher Wang Miao in Liu Cixin's The Three-Body Problem. In the game, societies rise during mild Stable Eras, fall to the extremes of Chaotic Eras, and are numbered in sequence, with each collapse recorded in a closing announcement. Civilization Number 137 is recorded as having advanced to a stage comparable to China's Warring States Period before succumbing to extreme cold, frozen as the game's world drifted into a long, deepening winter. Its era is the setting of one of the earliest sessions a player experiences in the game, among the first collapses a newcomer witnesses.
