Kachissat

Kachissat, also known as Daran V is a planet in the Daran star system. Kachissat is the home of a species of avians known as the Shesshran. The planet has a dense atmosphere, with an atmospheric pressure 3.4 times, and gravity force 1.65 times that of a standard Class M planet.

10,000 years ago, the planet was home to a species of avians known as the Tishiki. When the Fabrina star went supernova, Kachissat was devastated by the explosion, and many of the Tishiki died in the aftermath. Those who survived became known as the Shesshran, and spent the interim time rebuilding their technology. (TOS novel Ex Machina).
