Stars and their courses
After the collapse of the Dwarfish empire a new order was set up by the Elves. Taking the example of the old empire, they set up a new cast system with fey creatures at the top, and others at the bottom. This empire created a mini golden age of magic where culture was sustained for a short time.
The first rebellion was started by the Drow, but it put down and triggered a mass genocide against the Drow people.
The second rebellion was started by the humans. They were able to break away from the main empire and the nations of Tellus and Asgara were born. The elvish empire ended as brutal as it began, and a new era of humanity began.
