At storybrookers we just got an awesome Maleficent player, and she would love to find a Lily player to explore their mother/daughter relationship. You'd get to turn into a dragon and everything! Snow and Charming would really like to see her there too. Well....their muns would anyway. >.>
We would also really love to find someone who will play Cruella for us. We had this epic plot with her planned and the writer sadly had to depart, but we would still really love to do it. It involves werewolves and prison breaking.
Lastly, Rumple would especially like a Belle, and Regina would especially like a Robin. If you have any interest in any of these, or in any other character that isn't taken, please let me know! I'd be happy to answer any questions here or in the dropbox.
