About Atlantis Big Bang (where size really does matter) (atlantisbigbang)
The Atlantis Big Bang is a writing and art challenge based on the sci-fi drama Stargate: Atlantis. We welcome all genres and pairings; our motto is the more the merrier.
The goal is simple: authors write and edit 40,000 (or more) words in four months. Artists then have one month to create art to go with the stories. At the end, everything is revealed to the public in a BIG BANG of fic and art.
