Shaken by the loss of fae, the ur-treant Urliant awakens and marches on the Cracked Palace, home of Lolastre's Autumn Court. Urliant falls to Court of Eyes forces and is disembered in a ritual that successfully Shifts the first intact part of the Original Plane to Arborea, opening the way for a permanent gateway to the Shadowfell realm. (Fucken sad, even now, eh?)
