Archanis
Star Trek: The Original Series
Episode: TOS 019 - Arena
Star with at least four planets and the namesake of its sector, adjoining the Bajor sector, three days journey from DS9 and visible from the Cestus region. Relinquished by the Klingons along the Federation border by 2272, it became a hotbed a century later when Gowron renewed ancient Klingon claims to the system and entire area, threatening war if UFP colonies there were not removed. It was raided at least once by the Klingons.
