Ausul Raf is a deep smoking canyon of Iizus Yeldah. One hundred miles east to west and twelve miles at its widest, its deepest point is three miles down. From the peaks of Inzurakthol, chilling winds blow through this area, creating howling sounds that are both natural and not. Nearing the 6th century of the Horgon Era, a rival city-state to Kathodrarg arose in the heart of what was then just another part of the Cartáricil Forest. Refusing to bend the knee, the rival city-state of Lod Stohl warred with their rival. Five years later, with Lod Stohl on the brink of falling to Kathodrarg, the magocracy of Lod Stohl turned to powerful conjuration spells contained in the Shift Tome. It is said they were duped by Dispater, then posing as lowly fodder to his summoners. Instead of summoning an army of spine devils, the entire city and the land around it was shifted to a faraway system, leaving a smoking rift in its disappearance.
