Lonely Citadel

The Lonely Citadel was a gargantuan tower that was originally of Faerûn.

Location
This tower formed the top of a spire in the mountain range known as the Ice Mountains. It resided north of the dwarven stronghold, Citadel Adbar.

Structure
Only a single turret was attached to this tower.

History
In 1365 DR, the Lonely Citadel was spirited away from the Prime Material plane in a great burst of divine energy. The citadel later appeared in Mount Celestia when Torm was elevated to the status of a lesser deity. The tower itself came to form the heart of Trueheart in Mercuria.
