Teketekon Station was a special, secret and small shipyard-like station on the outskirts of Cardassian territory. The only vessel the station has actually ever serviced was the USS Phoenix-X. It was home to members of the Obsidian Order and the Tech-Team until it was annexed by Starfleet Security in 2383. (Star Trek: Phoenix-X: "The Deterioration", "Transphasic Meltdown)
