Iris looked at the runes that Lupa was holding up, and listened to the other students answers ... She honestly didn't know WHICH runes they were, but judging on the other kids' answers, they were witches runes ... Witches ruins... Iris had heard of them, they were fortune telling things, weren't they? "They're used to tell people about things that are going to happen, aren't they? And you only count the ones that are face up when you're making readings and stuff." Maybe listening to you're older brother came in handy
