Laeral Silverhand

Laeral Silverhand (pronounced: /ˈlɛərɔːl/ LAIR-awl) was one of the Seven Sisters, a Chosen of Mystra, and the Open Lord of Waterdeep, formerly known as the "Lady Mage of Waterdeep". Together with her partner Khelben "Blackstaff" Arunsun, they led the Moonstars, a dissident faction of the Harpers, which sought to guide the cities and countries of the North toward a shared destiny. One of the most prolific magic item creators in recorded history, Laeral was particularly adept at determining the abilities of magic items and could potentially do so merely by holding one in her hand without activating it. She also hid a gift granted to her by Mystra to deactivate or cause malfunctions in magical items that touched her.
As a centuries-old wizard, Laeral was one of the most accomplished spellcasters in Faerûn, though her powers steadily declined as she had to increasingly devote her energies to maintaining her aging body. Like all Chosen, Laeral's divine blessings were much reduced in the wake of the Second Sundering, as all gods took a more distant approach to interfering in mortal affairs. Nonetheless, her knowledge and facility with Weave-craft, as well as her silver fire, made her a formidable opponent.
