Chaos Canyon

Chaos Canyon is a vast, shattered gorge dividing the Midlands from Vulcan's Wrath. It was created by the very first Elementals, during the worst of the Emergence. Without really understanding what they were doing, a group of desperate humans joined their newfound powers together and shook the Earth itself. The end result was a canyon deep enough to swallow even the worst of the lava flow from Vulcan's Wrath, saving enough of the North American continent for humanity to survive.
