Taonas was an Ancient outpost on the planet Proclarush, virtually identical in design to the Antarctic outpost discovered under the ice of Antarctica on Earth. Taonas housed an Ancient star map and at least one active Zero Point Module to power its systems, including the outpost's control chair and shield, until SG-1 took it back to Earth. With the planet overcome by volcanic activity and the outpost's protective dome compromised by SG-1's Transportation rings entry, it is likely that Taonas has been destroyed.
