The Great Sand Sea
In the center of Dyskydia is a desert known as The Great Sand Sea. It is surrounded on all sides by a mountain range known as the Esotayl Mountains. It almost never rains in The Great Sand Sea since the mountains around it prevent much of the rain from getting to it. It is almost impassible without the use of Sand Buggies from The Coalition of Klynth. It has no readily available resources and as such is not owned by any of the major city states or sought out by them. Only the Coalition moves through it as an efficient trade route.
Some say the desert formed after a huge volcano underneath Dyskydia exploded wiping out a great civilization and forming the mountain ranges which keep it the desert it is today. Some also say that the traders of the Coalition are descendants from this lost civilization.
At the center of The Great Sand Sea are the Obsidian Flats.
