I think that those primarily working on the story should have their characters there...
That would mean we would end up with Talmid, Jonna, Stirling, Iamos and... well, the PE is apparently gone, so would Dewin work as fffffplayer's representative? That's five... Then there would be TheDude, being the main villain and all; Thingguy, because of his clones... hmmm... the last place is really dependent on the story. Chase might be more involved, Luke might be more involved, Peragrine might be more involved (we could replace Peragrine with Stirling if it turns out he plays a bigger part in the story, for that matter), another character might be more involved. it's honestly hard to say.
Now, you're just doing it on purpose!!! I demand you make me administrator to be able to edit your posts, so that I can edit out such monstrosities without having to ask you!!! :P
I don't think I need a representative. I think the cover should be made more storywise. Who are the important characters of the story? Considering that the writers' characters are probably all going to have a relatively big part, we have Talmid, Jonna Stirling, Iamos, (Drum), thedude, Thingguy and Luke (as founders and already protagonists of the story). That makes 7, 8 with Drumr and 9 with two Thingguys. Is it too hard for you to alter the base for an additional figure?
