The Shattered World
With magic use in the world reaching never-before-seen heights, magical energies began to coalesce into physical form.
By the time the hazards of this new form of matter were known, it was too late. The more dense the magical essence was, the more volatile it was, ready to go off at the slightest breeze of wayward magical energy. When it was set off from somewhere within the Rillian Imperium, it resulted in a chain reaction that detonated the coalesced magical energy all across the world.
The result, commonly referred to in legend as The Shattering, sundered the world more than even The Unmaking had. The entire continent that had been home to the Imperium was vaporized in the unimaginable explosions of wild magic that rippled all over the world. The entire surface of the world was reshaped, as the repercussions of the blasts shifted the mighty tectonic plates themselves, tearing apart ancient continents and shoving forth new ones out of the sea.
