Moon's Vengeance

Date: Roughly 3750 BC.

The event that ended the Second Age and shattered the aelvar empire. Druids, working under the influence of the Awakener, cajoled the Third Moon into leaving its orbit and coming crashing down onto the aelvar capital. The resulting devastation carved out mountain ranges and trenches in a huge circle around it, which still exist to this day.

Information recently uncovered by Repotaters in the Blood-thirst Wildlands points to one of the ultimate causes being one aelvar's reaction to the sadistic experimentation performed by his boss on his sister, who was judged "incapable of arcane manipulation" and thus a non-person. This sparked a chain of vengeance that ultimately ended an Age and brought down a multi-thousand-year empire.
