The Greet are an invertebrate xenos species that was annexed to the T'au Empire.

Their homeworld is a watery planet called Isla'su that is located on the outskirts of the Fal'shia Sept.

After being discovered by the T'au Air Caste, the Water Caste extended the Thraxians honourable greetings and an invitation to join the T'au Empire, offering them mutual protection, new trade opportunities and the exchange of technology.

The Greet allowed the Earth Caste to build many floating factories atop the surface of their planet-spanning oceans. This paid for the protection of their planet by T'au orbital stations and allowed the Greet to better contribute to the Greater Good.

Canon Conflict

On page 10 of Codex: Tau Empire (6th Edition), the Greet are stated to have been annexed during the First Sphere Expansion, but on page 28 this event is dated to 896.M40, during the Second Sphere Expansion.

The same conflict reoccurs in Codex: T'au Empire (8th Edition).
