Archanis IV

Archanis IV is the fourth planet of the Archanis system and the main planet of the Archanis sector. It was once a Klingon world, until the Klingon Empire relinquished claim to the planet and the sector under the Khitomer Accords to the [[United Federation of Planets].

In 2372, Gowron sent a message to the Federation Council, demanding that Starfleet abandon all starbases and military installations in the sector. He cited the Klingon claim to Archanis IV and the surrounding territory as being "ancient and indisputable". Several days later, a Klingon fleet was sent to Archanis and Gowron gave the Federation ten days to withdraw before they began an attack. 

Archanis was later attacked by the Klingons. Gowron told Benjamin Sisko that the Federation would have to officially recognise the Klingon annexation of Archanis for the war to end. 

Meron Byxthar had visited a Kreel asylum on Archanis IV at some point prior to 2381.
