This campaign takes place inside a Dyson Sphere.
The land of Kayhos is ruled by a group of Genasi known as the parliament. They enjoy great wealth while everyone else lives in poverty. Some of the members of parliament are quite powerful, while others serve those that are. Although the parliament does get together and actually vote on issues from time to time, it is really the Kahhore that decides things.
Rebellions against the parliament have taken place, and some even enjoyed mild success for a while, but the Kahhore always put an end to it in the end.
This world needs heroes to stand against the parliament and eventually against the Kahhore.
