Etymology and Lore

Rowling's main books, it appears in Pottermore, video games, and fan wikis as practical dueling magic from Dark Forces: A Guide to Self-Protection. Imagine a wizard flicking their wand mid-chase through Hogwarts corridors, billowing fog to slip away—like a magical fog machine for desperate getaways.
