Sun Empire
The Sun Empire is a prosperous empire on the continent of Ixalan, which is located on the plane of the same name.[1]
The empire has a capital (Pachatupa) and a central power structure. The emperor resides in the Tocatli palace. The human warriors of the empire command and ride dinosaurs, and they are protected by the magic of their sun priests. Pachatupa and the other cities are built to accommodate the dinosaur riders: high arches to allow their knights to pass through unobstructed.
The Sun Empire took the continent of Ixalan from the River Heralds, who lived there long before the humans. The empire still confronts the Hearlds on its borders.
The Sun Empire has recently been besieged by pirate raids by the Brazen Coalition and the advance of the Legion of Dusk. Caught between the invaders from the sea and the wall of jungle behind them, the Sun Empire rises with the ferocity of a dinosaur and the righteous light of the radiant sun to fight off its enemies.

The Sun Empire is loosely based on the Aztec culture.[1]
