The Stellistor Galaxy is the oldest and most populated galaxy in the known universe with more than 500 recorded solar systems with sentient life forms. It is located 11,023 parsecs from the supermassive black hole at the center of the Milky Way Galaxy. It does not exist outside our galaxy like Andromeda and other mapped Galaxies, but on the other side of the Milky Way in a parallel dimension. Peace in this Galaxy is maintained and enforced by representatives from 70% of these systems in a Concordia collective called the Supreme Galactic Alliance.  Those who have chosen not to join the collective are either not advanced enough in technology to be made aware of its existence or are hostile to the ethics of peace and unity that the SGA represents. The SGA firmly believes that the less advanced civilizations should be allowed to develop at their own speed and do not interfere with their progress. But the more hostile species would take advantage of that weakness and prey on these vulnerable planets. So the SGA has set up protective barriers of powerful armadas around the planets that cannot protect themselves and covertly fight off the alien invasions. These armadas are on constant patrol throughout the galaxy.
