Penthea grinned as they passed through the Leaky Cauldron. It was very obviously full of witches and wizards. "What if a mortal walks in here?" Which of course was followed by "You guys live longer?! Like, how much longer?" Because Pen knew her witch ancestors had not lived longer than mortals... mostly because they'd almost all died from one magical disaster or another.
"Our family is full of prophecies, so demons who want infamy or power in the Underworld attack us." That was the simplest explanation anyway. "You don't have a Book of Shadows? I thought all witches did! Don't you guys learn history in school?! I know witches here during the witch trials had them. We learned about that in History of Magic." Pen actually liked that class. Of course her professor wasn't a dull as death ghost, either. "Basically it's a record of spells, rituals, and in my family's case: of demons."
