The Builder Wars were a series of wars between humans and the Builders. They lasted for two centuries.
The wars were caused by a misunderstanding. Humans had been surveying the Builder home planet, designated Planet Z02-80535 by the humans. The team found no sentient life, unaware that the natives they had captured were sentient. When Trans-Planetary Mining arrived at the planet to begin mining, the Builders wiped out the survey team and the mining team.
Thirty million humans died in the Builder Wars. The wars ended in 2832 when the Builder planet was destroyed. (PROSE: Primitives [+]Loading...["Primitives (short story)"])
