Ruan is a world that I've had in my head for a few years now, and it keeps evolving and changing and eating up my other world ideas to make this big but vaguely laid out thing.
Luckily, through a World Design class I was taking, I had the chance to flesh it out a bit more, but it still has a long way to go.
Some of the basic survival gear one needs when traveling along the ruined surface world. It's basically turned into a vast wasteland, where duststorms are very common, and a thick black smog hangs around the lower parts, ruining all it touches.
