Heracles is a very massive and highly prominent object, located in the Anthrov Arm of the Via Sagittaria Galaxy. Heracles is famed for its ring system, which appears to be the largest set of natural rings in the galaxy. These rings, over 1.7 billion km in diameter, was the primary source of tourism of the system, attracting the construction of megastructures. The implementation of such has made Heracles an object of much Intragalactic interest.
Heracles used to be the center of certain anomalies, known to eject material into the regular universe from the Aeterna Caligne. This ejecta had many effects ranging from increasing the power of nearby Magi to causing negative psychological effects. Ejecta started appearing in the early 3,300's BCE before completely stopping in 10,826 CE. Heracles was likely an out-cropping of Sydiah's Hinterlands into the Via Sagittaria Galaxy, the only one of its kind in the galaxy.
After it lost its anomalous properties, Heracles quickly became obscure. Later on, as the United Federation of Star Systems reached the area, Heracles was cornered off and limited access was allowed. This was a result of scientific rediscoveries, involving its present yet muted anomalous properties. Scientists also tested the material of its ejecta, concluding that it was decaying material from the Aeterna Caligne. It was then when Heracles was discovered to be a one-way exit from the Aeterna, prompting further research in its capabilities.
As further research was being conducted. It was decided that Heracles was able to be used for a regional power source. As such, mega-engineering was permitted and carefully placed around the gaps of the ejecta rings, which would house infrastructure. This created a set of large artificial rings, which were built for various industrial/economic purposes. To the center of Heracles rests one ring, which are used for power collection and distribution. The outer rings have been populated since their construction, which has elevated Heracles' social status once more. It now exists as a small hub for regional travel and population, including tourism and historical value.
The planet and its spectacular ring system formed roughly 15 million years BCE. The planet remained unchanged until its anomalous activity began in about 3,300 BCE. The nation controlling it at the time, the Yohjan Confederacy quickly detected the activity and immediately dispatched a team of researches to study it. When the Yohjan Confederacy found out about its properties, it immediately began extensive research into not only them but the abilities it seemed to unlock or enhance in people who ventured near to it.
Once the War of the Final Transition began, the Yohjan Confederacy began deploying Magi enhanced with material from Heracles to counter their enemies' recent adoption of Magi of their own.
