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")
In the final draft script of "The Aenar", the Aenar habitat (so called in the script) was described as "a vast underground complex consisting of hundreds of elegant Aenar habitats built into towering walls of ice (NOTE: Though the Aenar are sightless and don't use artificial lighting, light from the powerful Andorian sun filters down through the ice, creating a dim, eerie glow)." Living quarters in the Aenar compound were referred to in the script thus; "Simply furnished, with smooth, icy walls. A large window affords a view of the underground complex."
The Aenar compound was depicted with a computer-generated matte painting designed by Doug Drexler. He created it in the style of Albert Whitlock's matte paintings from Star Trek: The Original Series. The digital matte painting was executed by Drexler and Mike Stetson. ENT Visual Effects Producer Dan Curry was thrilled with the result, calling it "a really beautiful interior of a giant ice cavern with Andorian architecture constructed inside of it that I think fans will really love; It's an exceptional shot."
