This will work sort of like FQF comms do, in that it's not an exchange but more a signup from a master list. Leave your prompts on this post and I'll collect them into a single post, from which we can then all sign up for what we want to write. Fics will be at least 1000 words, and if you're artistically persuaded then you can certainly sign up to do art instead of fic.
Your prompts can be from any book and of any rating, as specific or general as you'd like. Shippy, character gen, whatever. Anything to do with Narnia. I can't wait to see what you guys come up with. :) Leave any questions or suggestions in comments.
