Ahghairon’s Tower
'''Ahghairon's Tower' is a city landmark located in Castle Ward, Waterdeep.
History
Born in the Year of Great Riches (920 DR), Ahghairon of Waterdeep arrived in Silverymoon in the Year of the Red Rain (927 DR), yearning to learn magic. He was taken in and taught by numerous tutors. In the Year of Sudden Sorrows (941 DR), Ahghairon single-handedly destroyed a pair of young green dragons intent on attacking Silverymoon. Soon thereafter, Ahghairon left the city to learn more about Toril, but little is known of his travels. He had returned to Waterdeep and built his tower by the Year of the Blazing Call (947 DR), for that is where Magister Taline Telgara, “The Flame of the North”, found him after receiving visions from Mystra. By the Year of the Rings Royal (952 DR), Ahghairon was the official advisor to the War Lords of Waterdeep, and his history is thereafter wholly intertwined with that of the City of Splendors.
Description
Ahghairon’s Tower rises as a slim stone pinnacle with few windows and a conical roof four stories above the street. It is always quiet, never visibly changed by the passage of years nor disturbed by passersby. No one is thought to have entered it since Ahghairon’s death, thanks to a series of wards erected through the cooperative effort of Ahghairon’s apprentices (a mythal created with epic spellcasting), although in truth Lhoril Delhiirnyn stole the dragonstaff of Ahghairon before the wards were laid.
The tower is enclosed in a permanent effect similar to a forcecage, with a gap of 10 feet between the cage and the tower proper. If successfully disintegrated or otherwise destroyed, the forcecage reforms approximately 10 minutes later. Within the forcecage, the tower is enclosed in an invisible sphere], within the prismatic sphere is a time stop field, within the time stop field is a spell turning field, and within that ward is variant of the alarm spell that sounds a loud, audible alarm in Piergeiron’s Palace, Blackstaff Tower, and Herald’s Holdfast (far to the north in the Silver Marches). If the alarm is triggered, a walking statue is teleported from Mount Waterdeep to the tower and set to attack the intruder. Some have speculated that it might be possible to bypass the wards with secret tokens of recognition or pass-phrases, but if such things exist, no one has admitted knowledge of them.
The contents of Ahghairon’s Tower are largely unknown, although certain legendary items, such as Ahghairon’s great cloak'', are said to lie within. Iron and stone golems, as well as lurking spell traps, are also said to guard the wizard’s treasures.
