Archenar is a star system near the center of the Federation. It lies at the junction of two ancient hyperspace jump routes, linking Sol, Centauri, Hannaford, and Serenity. Archenar contains a nearly abandoned industrial planet (Trusa) and a large, bustling space station (Sirrusa). Ship traffic is a mix of Federation military and commercial vessels.
The name of the system, planet and space station are based on the centre characters of the critically acclaimed game series Myst made by Cyan. The system name The planet Trusa is an anagram of the father in the game Atrus, whilst Sirrusa and Archenar itself are named after Atrus' sons, Sirrus and Achenar.
