Blackstaff Tower

Blackstaff Tower (previously Arunsun Tower—renamed by Khelben in 1322 DR ) was the home of Khelben "Blackstaff" Arunsun. The forbidding structure is one of the most recognizable landmarks in the Castle Ward of Waterdeep. It was also the home of his apprentices and his consort Laeral Silverhand. The tower is proof against Scrying magics.

After the death of Khelben, his heirs to the title of Blackstaff used the tower as both a home and a place of power. In fact, the tower became so linked to the Blackstaff that, upon the death of their master, the heir must immediately travel to the tower. On at least two occasions, the Blackstaff died outside of the tower and the heir was driven insane until they returned to the tower.

The fourth Blackstaff modified Blackstaff tower to allow the spirits of each former Blackstaff to communicate with the present holder of the title. While in the tower, the Blackstaff is also aware of every person in the tower or within a few feet of the tower.
