The Scar

The Scar is the centerpoint of one blighted wasteland becoming another. Following the subduing of the Great Rift by Riza Yellowfang, a powerful magical construct known as the Great Winder was made here, which sought to contain the seemingly neverending flow of evil outsiders into the Material Plane. Although this worked for some time, Riza was slowly corrupted and driven mad by her proximity to the Rift, and she would begin to tamper with calling to and communicating with the eldritch powers in the deep places of reality.

When Oltar confronted Riza, and they each disappeared from this plane, a shard of Riza was left behind - seemingly all of that which strove towards the formless darkness. This doppelganger came to be known as the Witch of the North, and she terrorized the land of Alvion for many years before her undoing in The Shattering.

During The Shattering, the Great Winder was finally destroyed, but with it an apocalyptic level of magical energy, thus far contained, was unleashed upon the wastes of Archeron. For miles surrounding the epicenter, the sign of the being which Riza had strove to reach was left burned into the land itself - a fingerprint of the eldritch being attempting to worm its way into reality. Luckily for the denizens of the Material plane, this being was unsuccessful in his efforts, though his mark remains an eternal reminder of his presence, just outside.
