Greet

The Greet are an invertebrate xenos species that was annexed to the T'au Empire during its First Sphere Expansion.

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

After being discovered by the T'au Air Caste, the Water Caste extended them honourable greetings and invitations to join the T'au Empire, to ally themselves through the appeal of mutual protection, trade and 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 orbital stations and allowed the Greet to better contribute to the Greater Good.
