Also called the Arbiter Spire by the group that first discovered this structure, this is a mysterious floating tower that constantly shifts and rotates. The Skeleton Bard and an Arbiter called Jure were encountered here, alongside infestations of Fire Elementals, Aberrations and Sinspawn.
"A monument to accumulated knowledge and sciences that would make the god Nethys blush. This careening tower seems to pierce the heavens themselves, but is not one solid structure. Rather, it is a conglomeration of rooms and hallways constantly shifting and floating about the central axis. Walls and shelves part ways to float about in a magical dance round and round the tower, only to form completely new rooms and layouts of each floor. This shifting makes accessing one room to another difficult and unpredictable, and when you enter one room or floor, there’s no telling where you may be swept off to next."
