Peruvian Instant Darkness Powder is a magical item imported by Fred and George Weasley and sold by Weasley's Wizard Wheezes. This darkness powder creates darkness when used, allowing the user to escape. As its name indicates, it was originally invented by the wizarding community in Peru, which is the place from which the Weasley twins import the powder. The darkness produced was resistant to many light-casting spells, but the Hand of Glory is the one known way to find the way through it.
