The Star Chamber was the informal name given by Earth Starfleet Captain Erika Hernandez to a laboratory in the city-ship of Axion.

The Star Chamber was the location where the Caeliar scanned, analyzed, and selected possible habitable locations to settle Axion after the loss of their former planet Erigol. Initially only the Caeliar scientists worked in the Star Chamber, but Erika requested to aid in their search, unable to find any artistic pursuits she was interested in.
