The Orion Era was a period of history that covered much of Orion history.

It began with the signing of the Treaty of Kammzdast in 15,956 BCE (reference stardate −179/56), which regulated the use and training of Orion slaves. This made them an important commodity and a key factor in interstellar politics around the Rigel system for over ten thousand years. (FASA RPG module: The Orions: Book of Common Knowledge)
