[@Infamous Empath] Sorry, I don't think it was clear - you can use settings and characters that you've created before, but the entry itself has to be written specifically for this contest. No excerpts of already-existing works. Besides this I'd also advise against putting bits of your novel online if you ever intend to publish - publishers can be pretty strict about their plagiarism checkers and it'll be impossible to completely remove your writing from the database.
