Invisible Fortress:Thorns

Thorns used to rival Lookshy and Nexus in might, and paid tribute to the Realm. It was a center for artisans, intellectuals, and warriors.

Then, almost over night, Thorns was lost. In RY 764, the Deathlord Mask of Winters assaulted Thorns with an army of undead, and the rest of Creation turned its back on the city. The city fell, the people died, and the entire area became a Shadowfell pocket. Today, people rarely speak of Thorns, and when they do, they avoid mentioning it by name.
