The Mark of the Erasure, also known as the Mark of Erasure, is a region in the northwestern part of Hieron. As its name suggests, it bears signs of impact from the Erasure cataclysm. Because details of the cataclysm are hitherto ambiguous, so too is the Mark's exact nature.
The area surrounding the Mark of the Erasure are cold and snowy, and becomes colder and more inhospitable the closer one gets to its center. Goblin societies here have been ravaged by word eaters. The snow elf village of Auniq is located here.
At the center of the Mark of the Erasure is the ruins of a once-massive tower of Samot. Paradoxically, weather at the very center is balmy and warm compared to the raging snows that surround it. The various parts of the ruins are gateways to alternate worlds.
