Most of the heroes are because the old adage "write what you know" ;)

Is the world embedded in some kind of solar system and if so, how does it look like ?

Are the inhabitants of the world aware of celestial mechanics ?

There are 7 planets, with an 8th one that was shattered. The Luminar gave the Dragons their own planet in the days of yore, which would be my version of Mars. The Dragons had a massive civil war after they conquered and butchered other worlds and lost the favor of the Gods, shattering their world and traveling to the main planet since it was next door. That began to war of the Dragons and the Dwarves, though the giants were in on it too. 

There are around 4 planets that are barren save for some ruins. One planet is the main one, Maroleth, and two others havew inhabitants. One is unexplored but strange activity is noted by astronomers, and the other is teeming with endless hordes of Gundarogs. 

The inhabitants do know of celestial mechanics, yes. At least most learned ones.
