Wandless

The Wandless were witches and wizards who had become vagrants and homeless during Voldemort's regime at the Ministry of Magic. As their name suggests, they possess no wands, presumably confiscated from them by the Ministry. Based on speech from the Death Eater, Travers, they are witches and wizards deemed to be unworthy of magic, and were most likely Muggle-borns. They were only seen in Diagon Alley, though it is unknown whether this was the only area they inhabited. It is also unknown why these individuals were not in Azkaban, though it is likely that over the course of the year, the prison had been filled, and the Wandless were merely forced to live as vagabonds.

They tended to beg and plead with more prosperous witches and wizards that gave patronage to the street's establishments, though they were thoroughly ignored, and in many cases abused by Death Eaters and their supporters. Some of them had gone mad by the uneasy transition of life-styles, as one was seen to attack Hermione in a fit of rage and incoherence, who at the time was disguised as Bellatrix LeStrange
