This is epic, sprawling fantasy adventure in the same vein as Dune. For this price it is an absolute steal. It would not surprise me at all if this was taken up commercially. Enjoying it a lot.
Edited to add much later. I've now read a lot of 5 star rated Kindle published books in this genre. They've been fun to read. This is better than most of them. There's more substance to the world and more interesting characters.
