The Dispossession was a period of Orion history, lasting some three centuries from 1003 AD (reference stardate −10/03) to 1301 AD (stardate −7/0101). It marked a time when Grey Orions were forced out of power in Orion society and into slavery. It was closely linked with the Orion Empire and the Reverse.
