Citadel of Conjurers

The Citadel of Conjurers, originally known as Dun-Orthass, was a dark tower, located within the foothills of the Earthspur Mountains at the mouth of the Moaning Gorge, that was built in the final years of the Narfelli empire.

Description
The citadel was constructed from black stone. Beneath the tower proper was a labyrinthine series of secluded chambers and catacombs that were believed to hold a number of artifacts and treasures from Narfell.

The sages of Faerûn identified the citadel as powerful evil node. The demonologists and experts of fiendish lore and demoncysts believed the halls of the citadel to be infested with demonic activity.

History
The citadel was originally built in the Year of the Starry Shroud, -153 DR, in the waning years of ancient Narfell. When the Great Conflagration erupted between Narfell and Raumathar the following year, many Narfelli refugees along with the final Nentyarch of the realm, Rheligaun, fled to the citadel and met some unknown fate. It was believed that many of them were hunted down and sealed away by vindictive Raumathari battlemages who sought vengeance upon their former countrymen.

Throughout the ages, many Impilturan heroes, among them King Sarshel "the True" and King Nord, have walked the dark halls of the citadel and returned to the kingdom and shared their tales.
