Helidus System

The Helidus System is a star system located in the , in Subsector Xitalis of Sector Auvidus. The system orbits Helidus, an F-class white star, and is notable for its large number of inhabited planets and moons, as well as for Fortress Markalus, a major operations headquarters.

==Trivia==
*The Helidus System was first created during the summer of 2014 using a set of random star system generation rolling tables, and it took about four straight hours to roll up. It then sat on Anon's sandbox wiki for about two years before finally being published here in June 2016.
