Concept Corner #3

Concept Corner #3 - Daemonium
A delinquent stumbles upon a strange key that unlocks a mysterious, magical library underneath the one in town - a library frequented and staffed by monsters, demons, and other creatures from stories and mythologies. The main character, upon being discovered, is set to work at this strange library, making sure the books stay on their shelves and the characters inside don't get any bright ideas...

This would probably be a teen series. It would draw a lot of inspiration both from existing stories as well as from my imagination - a mix of familiar and not-so-familiar. I don't know yet what kind of existing stories I would focus on if I ever write this - they'd have to be public domain, and ideally something not done to death just yet (so with Rick Riordan's hold on the mythologies, for example, it'd be difficult to use those in an original and non-derivative manner). Arabian Nights, maybe...?

(Edit: Now that it's on my mind, the Arabian Nights would make an awesome theme. The main character could be related to Scheherazade or something. I don't think the idea's been overdone yet - or maybe even done at all - and I'd have plenty of characters and stories to draw from. Don't you just love the rush a good story idea gives you?)
