The Ashen Maw serves as a violent physical and magical quarantine zone between the fertile Dawnlands and the cosmic rot of Azági's Rift. It is a jagged landscape of volcanic ridges and caustic swamps where the sun is perpetually obscured by thick soot. Frequent tectonic tremors and acidic rains define life here, forcing inhabitants to endure profound ecological violence to maintain the Empire's line of defense. If this barrier fails, the continent will fall.
