Light of Avanor
Luminite is the civilized landmass while Shaderian is in process of being colonized by force. A process which has slowed with the current internal struggle.
Avanor is a land covered in a perpetual darkness. There is no sunlight, but there is many light sources through magical means. Magical Latern's known as Golden Lamps provide adventuers and cities with light.
Three Kingdoms contest for rulership of Luminite. They are made up of a variety of fiefdoms and function in a Feudal State. Currently two of the Kingdoms are at War, with a Third staying neutral at present. The war is known as War of the Suns.
