"Adventures in the Mad Lands"
"A world of Chaos
"In the center of the world is a land hammered by the weather, tortured by insane gods, plagued by grotesque monsters and haunted by magic. Only the bravest survive in the Mad Lands."
An insane fantasy setting is the only way to describe it. Not your normal swords and sorcery by any stretch. Also, low-tech compared to most fantasy settings.
