Description[edit | edit source]

Almarcrux has an atmosphere of methane and ethane. Despite the distance from Caspian, the energetic young star heats the surface to almost temperate levels. Thick ground fogs are common at the terminator, where water ice frozen during the long dark side night meets the warm air masses from the day side. The crust is mainly composed of copper with deposits of sodium.

Almarcrux's abundant water and relatively mild temperature and gravity have placed it on the short list of terraforming candidate worlds. However, there is significant opposition from eco-ethics groups, who assert that Almarcrux's primitive methanotrophic bacteria may be a precursor to a full-fledged native ecology.
