Castle Perilous

On a single night in 1347 DR the dark stone and iron fortress called Castle Perilous was raised by the work of demons of the Abyss. It was located on a rocky crag on the shore of the Lake of Tears in Vaasa. It was the seat of power for the lich Zhengyi, the Witch-King of Vaasa. With the aid of his demon patron Orcus, Zhengyi gathered an army of dire wolves, giants, goblins, orcs, and undead to conquer Damara.

It was destroyed by Gareth Dragonsbane and his party of Seven in 1359 DR. Castle Perilous is now just a crumbling ruin, filled with lurking monsters and frequented by adventurers looking for remnants of Zhengyi's magic. The heaps of rubble are often seen topped by Chromatic Dragons of all colors as Tiamat plans to use it as a staging ground for the dragonfall war with Bahamut who has his new centre of faith in Damara.
