Re: plot panda
You can certainly write sequels to any fic that you write for this fest, but any submitted fic must meet all of our requirements (i.e., it must fulfill the prompt, meet the length requirements, be beta-read, and submitted by March 15th, etc.) and be complete in of itself.
Like Chamber of Secrets is a complete story and part of series so that would be acceptable, but chapter one through five of Chamber of Secrets is just a part of a story so wouldn't. Does that make sense?
