The Aenar compound
The Aenar compound was the main settlement of the Aenar race on Andoria. It was located in a vast tunnel system in the Northern Wastes. Due to the extremely secretive nature of the Aenar, the compound was surrounded by a dampening field, and contact with the outside world was very rare. Despite this, the Andorian chancellor had means of contacting the compound. (ENT: "The Aenar")
