During the height of the Shattering, reality ruptured beneath the Trine Peaks range. Resonance collapsed inward, forming a vast and unstable wound later named the Aethergrave.

This rupture became both a sink and a source of uncontrolled power, warping geography, spawning anomalies, and altering the flow of magic across the continent.

The Aethergrave remains one of the most dangerous and poorly understood features of Velthuryn, its influence reaching far beyond its physical boundaries.
