Archanis IV

Archanis IV, or, more simply, as Archanis, was the inhabited fourth planet in the Archanis system. This system, located near to the Federation-Klingon border, was in the Archanis sector, in the Beta Quadrant. (; )
In the late 2260s, an alleged Federation research outpost on this planet was attacked by unidentified raiders. A hundred civilians were killed in the raid. This was one of several incidents that had taken place since a truce was declared between the Federation and the Klingon Empire. Although there was no proof of Klingon involvement in these incidents, some in the Federation believed them responsible. The Klingons claimed that they had observed the treaty to the letter for three years and that they were not responsible for the raids. In 2268, while under the influence of the Beta XII-A entity, Pavel Chekov was made to believe he had once had a brother, Piotr Chekov, who had been killed by the Klingons at the research outpost on Archanis IV. In reality, he had no brother; the entity wished to foment hostility between the crew of the and the Klingons. () 
Circa 2272, the Klingons relinquished their claim on the Archanis sector to the Federation. ()
Prior to the beginning of the , Gowron sent a message to the Federation Council, telling them to abandon all starbases and military installations in the sector. During the war, the planet was raided by a Klingon force. As a condition of ending the war, Chancellor Gowron stated that the Federation must allow the Klingon Empire to annex Archanis and other worlds captured by Klingons. Captain Benjamin Sisko told the Klingon leader that he couldn't count on that condition being met. In 2399, as depicted on a star chart in Fleet Admiral Kirsten Clancys office at Starfleet Headquarters, the Archanis system was in or near Klingon space. (; )
