Severing of the Planes

Geological / environmental event

Facing defeat at the hands of the (re-united) First Cohort, Lolastre pours her life essence into her ritual beacons, sending a catastrophic surge of power through the connected beacons and Unkept Road network and threatening to tear down the Veil separating Arborea and the Shadowfell. Unable to rectify the breach, La'had, along with the powerful Yhagrex Horde and Owena magicians sever Arborea's connection to the Veil, sending Arborea adrift in the endless Void Sea. Immediately, planar travel to Arborea is ended. (Fuck, that's some heavy shit.)
