What is it? I promise it's all good. :)
From now until midnight Saturday 28th April, UK time, they'll be collecting prompts for the battle in the comments to the above linked post. Then the day after, Sunday, a list of prompts will be posted up and it's a free for all to create art/fic/vid etc about any or all of the prompts with the aim of creating lots of lovely Teyla fannish goods.
