Supreme Alti System

The Supreme Alti System is how the Alti Dominion got powerful. In this system, they found a precursor Dyson sphere, meeting all their energy needs easily. There is also a large precursor shipyard orbiting it as well as automated mines. The Alti military became very powerful in a short amount of time. Additionally, they reverse engineered some of the precursor weapons there which is where they obtained the time dilation device (TDD) technology that they so commonly use and rely on from. The Supreme Alti star itself is class A. This gives the sphere a particularly massive output. However, they were not entirely successful, as their version of the technology did not come close to the potential power of the original Rikavi Ancients design. This system is a very valuable target for other factions, so they make sure to defend this place exceptionally well.
  Due to the relatively long name, the Supreme Alti system is sometimes abbreviated to the SA system. The system had this name assigned to it by the Alti Dominion government as propaganda, and to show the sheer military strength of the Dominion. All planets of the SA system are very cold and dark because of the Dyson sphere which captures almost all of the star's radiation. The Supreme Alti system is located many thousand lightyears away from the Kevra System, the Traxilax home system. On the massive scale of Arcturus, thousands of lightyears is actually very small, perhaps putting the size of the Arcturus factions into perspective. 
  Planets:
SA I - thick, toxic atmosphere which has mostly condensed into a liquid
SA II - ice giant
SA III - ice planet. Almost purely ice.
SA IV - ice giant
SA V - largest planet in the system, ice giant
SA VI - barren rocky planet
SA VII - almost perfectly flat other than the asteroid craters left from asteroid impacts (there is almost no atmosphere at all).
