Heya guys, this is Dylan!
My character Ashley comes from a line of magical beast hunters. For generations, they've been travelling to places that seem to be under attack by magical beasts or dark creatures, and taking care of the problem--be it relocating them, or putting them down. Gilderoy Lockhart received a lot of fame from his books about saving the day from these kinds of creatures, though in truth he oblivated the people who have actually defeated the creatures and took credit for their work.
I'm imagining that the community for this line of business is rather small and inter-connected, passing lore and other such materials between them, and always having a resource or a friend to help in a bind. As such, they would immediately notice Lockhart as a fraud and would dislike him. Of course, it would be nearly impossible to prove any of this and they'd likely get ignored by everyone who's fawning over him.
I realize that Lockhart would actually be a professor during Ashley's last year of schooling, and I had an idea that would cause this to become a point of conflict. Ashley's aunt has been working in the far east, hunting Yetis. I'd like to have her go missing around the time that Lockhart's "Year with the Yeti" is published, and have the family go looking for her because the book seems to describe her work. When they find her, she'll be completely disoriented and need to be hospitialized. Also, all of her notes will be gone. Not long after, Ashley is forced to learn his favorite subject under Lockhart's direction. This will be especially difficult, as that book was a required textbook for that year.
I was wondering if it would be alright to use him in this way, since we know that this is the sort of behavior Lockhart is known for.
