Desert of Sar'Aya

SOURCE Rising from the Eastern Desert, Sar-aya was the first of the gods to note the new animals crawling her sands, probably because there were so few animals to begin with. And so she saw mankind and that they could think more than the others who searched for water in her sands. And so she gave them the ability to think, and as thanks they worshipped her. She gave them a concept of justice and so they created a society. But the desert was hot and dry and they could not survive there, and so she pushed them towards the other gods, who were better suited to care for them. But still she loved them, and so when they left her, she cried a thousand tears. Those tears fell and became the Asaki, the rivers of this world, and Shai the great lake to the west, and they were some comfort in their mother’s grief. When the first of them died away from her, she was surprised that they brought his bones back to her, and set him in her sands. She took his body and his spirit, and finding that he had been a good man, she welcomed him to one of her oases, and as each of his brethren died and cast their bones into her, he gained company. But those bones of bad men, those she doomed to wander her dunes, scoured by sandstorms, forever.

Geography

A large desert, the edge is passable, but as you get deeper there are no oasis and the sand is thick, making it impossible to get beyond and see what she holds.
