Klin'sann, the central planet of the Imperial Klingon States, allows, but restricts, freetraders. Here, tariffs are high, and so the black market thrives. The Klingons are willing to trade the planet's rich resources for the goods they need so desperately. Klin'sann was first settled in the latter part of the Four Years War by a splinter group of Klingons. The group, led by Admiral Kamato, attempted a coup on the Imperial Throne during the war's confusion. The Chancellor, who had foreseen the attack, quickly defeated Kamato with a large Imperial force. Kamato and his remaining followers retreated into the Triangle to await another opportunity. They found Patterson's Place, a planet inhabited by a small group from the UFP. The Klingons destroyed the existing colony, established themselves, and renamed the planet Klin'sann, or Little Empire.
