A enormous floating Shadow Object.
The Shadow Spires were the places where Bael'Zharon gathered his forces.
During the The Fourth Sending of Darkness arc, Shadow Spires appeared at different towns.
Arwic as well as Tufa were destroyed by the forces coming from these Spires.
The Spires were destroyed during the
Twilight's Gleaming event. Their remains can be found near quite a few Isparian towns, for example the Fallen Shadow Spire of Cragstone:
