Azati Prime
Azati Prime was the Xindi-inhabited prime planet in the Azati Prime system of the Alpha Quadrant. It had at least a single moon. ()

The planet was mostly covered by water, with the few small landmasses not containing any life. The water was suited for Xindi-Aquatics to move in without protection. Degra described it as bleak and desolate, barely habitable. All of the Xindi facilities on Azati Prime were located underwater, including the construction yards for the Xindi weapon. ()

According to Degra, it was a diverse community with over a thousand Xindi-Arboreals and Xindi-Primates. Degra also claimed it contained an Insectoid deuterium facility. ()

Degra visited this planet shortly before traveling to the Calindra system to test a prototype of the Xindi weapon in December 2153. ()

In February of 2154,  reached the system after a long search for the Xindi weapon. Azati Prime was one of two inner planets detected to have substantial Xindi activity at this time, and the weapon launch was imminent.

The Xindi-Insectoid assault shuttle obtained by the crew located the weapon on Azati Prime. Once the Xindi realized the Humans knew where the weapon was, they relocated it to the Xindi Council planet. ()

By 2259, multiple star charts showed the Azati Prime system as part of Federation territory. (SNW: "Strange New Worlds")
