Star Trek: Peaceful Occupations
An independent class M world near Federation space, Klaestron underwent a long period of civil war, which finally ended in 2339. They now have a unified world government. They are known to have had close ties with the Cardassian Union, and signed a peace accord with the Dominion very early on. However, they remain generally open and friendly towards the Federation too. They have not been on good terms with Bajor.
In 2374, the USS Agora NCC-5099 was sent to expel the CDS Dabray from it’s hide-out in orbit of Klaestron IV, and achieved this by contaminating the Cardassian vessel and encouraging the Klaestron’s Minister Werr to send them away on medical grounds.
