Ahghairon's dragonward

Ahghairon's Dragonward was a powerful mythal cast by the famous mage Ahghairon over the city of Waterdeep.

Centuries ago, Ranressa Shiard returned as a hero from her journeys to Waterdeep atop a mighty dragon. Although she was welcomed home, the appearance of her mount flying over the city unsettled the majority of the populace. Ahghairon crafted this mythal to allay their fears.

Centered under Ahghairon's tower, the mythal projects a permanent 12,800 ft. dome which encompasses the city. Any creature with draconic blood that tries to enter the city is overcome with an overwhelming urge to leave the area, never to return. However, any draconic creature that touches the Dragonstaff of Ahghairon is able to bypass the dragonward for as long as the staff's wielder allows or until the creature is struck by the staff.
