The Greet joined the Tau Empire after the Earth Caste agreed to build them many floating factories in a negotiation led by the Golden Ambassador.[1a][1b] This in turn paid for the protection of their planet by Tau Space Stations and allowed the Greet to contribute to the Greater Good.[1a]
The Farsight Expedition's Grand Reclamation Fleet included Greet Stealthers as auxiliary allies, alongside Tau vessels, Nicassar Dhows, Domati Wyrmships, Vespid Nest Vessels, Kroot Warspheres, and Demiurg Bastions.
During the Fourth Sphere of Expansion, Greet mercenary Lineships were included in the Tau Fleet, fitted with Slipstream devices. When they entered the Warp, the mercenary ships were attacked by Daemons, including the Greet Lineships, the Ostense Council's Winged Discs, Human Cruisers and Cutters, Kroot Warspheres, and Nicassar Dhows. The Daemons ripped open the craft, and physically carved the crews apart with weapons, bare hands, and mouths.
