The Hand That Sings was a living spell, created by one of Halaster's apprentices some time prior to the 14th century DR with use of the handfang and magic mouth spells, who was infamous for haunting Brindul Alley in the Trades Ward of Waterdeep. The people of Waterdeep, unknowing that it was a living spell, assumed it to be an apparition or phantom.
Having been created by a combination of handfang and magic mouth, the Hang That Sings had the appearance of an animated, severed human hand with a mouth in its palm. Many claimed it bore a resemblance to the holy symbol of the deity Moander.
The Hand That Sings was easy to provoke, but it did not hold grudges.
As befitting its nature, the Hand That Sings could engulf other creatures like a closing fist or slam them with its whole mass. Any being struck by the latter means of defense was also struct with the same effects caused by the spells originally used to create the Hand, namely handfang and magic mouth.
The Hand That Sings spent its existence following the barely remembered dictates the apprentice that had created it. Typically the Hand would would drift along Brindul Alley at night, taking no notice of those who didn't provoke or follow it. All the while singing in an eerie manner ancient, fragmented ballads of the Sword Coast and love songs.
Though Hand was far more well known for snatching from passersby any valuables that it fancied, especially magic items, and occasionally attacking them. Typically in the form of strangulation or tripping them into fatal falls.
