The story is in a modern world with magic, so I can fudge a bit, but I'd prefer to ground the attitudes of people around her in real myths as much as possible. Legends and stuff now considered outdated are fine, since I may still be able to adapt it to the story's world. Also, now that I think about it, if anyone has anything on this that's UK-specific, that would also be helpful, as a later part of the story takes place in London.
