Rassalantar's Keep

Rassalantar's Keep was a set of ruins that once served as a fortress for the warrior Rassalantar.

Geography
The keep was not far from the Sleeping Dragon, which was east of the hamlet of Rassalantar. The Long Road traveled north of Waterdeep and passed the Keep Woods, which masked the location of the ruins.

Interior
Within the dungeon was a permanent teleportation circle that was used by Rassalantar to communicate with the Blackstaff.

History
As of the, it was ruined and occupied only by tramps, doppelgangers, and other monsters.

Around this time, the caravan stop village of Rassalanter, sprung up east of the ruined keep.

Over the next century, most of the keep's stones were dissembled and used for construction in nearby settlements. All that was left was the underground cellar and dungeons, both of which had flooded.
