Parvati stops believing in Divination.
The rest is up to you. If it's just temporary insanity from her, or long-lasting is up to you. So is the length of the fic, but it would be nice if you made it a little longer then a drabble. :)I wanted to make a minor character challenge, as I always find them very interesting.
if anyone have any ideas to challenges, let us know! And continue posting your fics here, or asking for help to them, even if things are a little slow right now.
