Two decades ago, a historian and researcher named Niuna Estrod came to Kenabres to write a history of the crusades. Estrod constructed a tower of pale gray stone to hold the volumes of history he wrote, as well as other tomes and scrolls acquired from traders and returning crusaders. Ever since Estrod's death from food poisoning 2 years ago, researchers and wizards have occupied the Tower of Estrod for short periods of time, using it as a temporary library or laboratory. These temporary residents pay a small fee to the city in order to make use of the tower.

Indeed, cultists were found within the tower. A tiefling witch and follower of Baphomet named Faxon discovered in the basement of the tower, along with a shrine to the Lord of the Labyrinth.
