Demelza looked over at Katie with a dark amusement when Katie caught up with her. "I mean, I'm the lowest crest there is," she answered easily with a shrug. "My parents died when I was younger. My neighbor, Annie, took me in during breaks from Hogwarts. I moved out right after graduation and found my own way. The problem is my way is not exactly lucrative in the monetary way. So, really, I'm lower crest and am okay with that."
