History & Background (Dossier)[edit]

Atsa is a poorly developed world, with the population mainly clustered around the large downport and surrounding industries. The world is mainly important as a naval installation and communications link, with several squadrons of courier ships stationed in-system. A naval squadron backs up the considerable system defenses. Atsa’s significance as a refueling point on the Cronor approaches was amply demonstrated in the closing stages of the Fifth Frontier War, when an Imperial deep-strike squadron from Quar attacked the system, intending to secure refueling facilities for the following assault squadron, which was engaged in a daring attempt to attack Cronor itself. Despite the assault force managing to gain a foothold at the starport, the attempt was unsuccessful, and the attackers withdrew. The port has since been rebuilt and greatly strengthened to resist a future attempt.

The damage caused in the Battle of Atsa is still evident, and security is very tight at the port. A project is under way to salvage the orbital debris from the action. Scientific craft and tugs are in constant activity around the system
