The Magus System
The Magus System has a sun similar the Solar System of Earth as well as some planets in similar orbits like that of Mercury or Venus. The entire area of where Mars would be is a solid ring of stone on the inside of the ring it looks like a normal planets landscape on the outside where it is always dark it is barren. There are six planets in perfect synchronized orbits in the habitable zone.
Each planet is where a major race evolved on. There where guiding forces involved but they are still unclear. It is believed the Magus System is a search for the perfect slave race. The Gods and their role in this is also unclear. It is not known for sure if it is one God acting as all or many fighting with each other for control of the ancient magic relic that is a whole star system.
Some sages say that the Magus System is just a component in an unfathomable magic device used to destroy Gods and rule all the entire multiverse. It is said the exist in all planes and are all moving to position them selves or collect more magic relics and races or both.
