Shesshran

The Shesshran is a race of sentient avian raptors native to Kachissat, or Daran V. The Shesshran are an aggressive, and highly individualistic species. The Shesshran require an atmospheric pressure 3.4 times, and gravity force 1.65 times that of a standard Class M environment.

10,000 years ago, the Shesshran were originally known as the Tishiki. Because they had no use for a planet with a standard Class M environment like that found on Daran IV, the Tishiki offered the planet to the Fabrini when they learned that the Fabrini star would soon go supernova.

When the Fabrini star did finally explode, the death of the star had a serious negative effect on Kachissat, killing many of the Tishiki. Those that survived lost much of their technology in the chaos, which would later become known as the Great Die-Off. Over the next 10 millennia, the survivors became known as the Shesshran, and evolved into a race of avian raptors.

The Shesshran first made contact with the United Federation of Planets in 2263 when the Vulcan crewed USS Intrepid (NCC-1631) entered the system to conduct a survey of the system. The Intrepid was detected by the Shesshran, who launched an attack on the Intrepid, despite the Intrepid's superior technology. They subsequently entered into a dialog with the Vulcans, but asked them to leave the system when the Vulcans refused to share technology with them.

When the Fabrini ship Yonada appeared in the Daran system, and was found to be on a collision course with Kachissat, the Shesshran prepared to attack the world ship. However the USS Enterprise (NCC-1701) was able to put Yonada back on course for Daran IV. The Shesshran were at first reluctant to share their star system with the Fabrini descendants, but later consented to allow them to settle Daran IV when archealogical evidence was uncovered proving their ancestors had indeed promised Daran IV to the Fabrini.
