==Trivia==
*While there is in fact no actual star with the designation "Sigma Octanus," there is one named "Sigma Octantis," a slight spelling change, located 270 light years from Sol. However, it is impossible to be the same system for a number of reasons. The real-world Sigma Octantis is classified as a F0 III-type giant instead of a binary star. In addition, it would make Sigma Octanus the second furthest known UEG colony, significantly further than the Outer Colony system 23 Librae which was considered to be "behind enemy lines" by 2535. Furthermore, the traveled from the system to Reach in less than a month. Traveling over 250 light years in such timeframe would be an impossibility with human slipspace velocities.
