Peruvian Instant Darkness Powder Display
Brilliant Weasleys' Wizard Wheezes
A Weasley Predicament
Weasleys' Wizard Wheezes, Diagon Alley
As the name implies, this imported product produces a shroud of darkness instantaneously. Despite being sold alongside joke products at Weasleys' Wizard Wheezes, this item can be quite dangerous in the wrong hands. Draco Malfoy employed it multiple times leading up to the Battle of Astronomy Tower, allowing him to smuggle Death Eaters into Hogwarts. Following this incident, purchases of Peruvian Instant Darkness Powder at the joke shop were more scrutinised.
