We used Plenair as an NPC because 1) we didn't really think anyone would app her, and 2) she has so little in the way of canon. She has appearances, but she basically says "..." exclusively, takes almost no actions, has no history. Even silent protagonists, like, say, Chrono from Chrono Trigger, can be looked at in terms of their actions.

So yeah, as much as we hate to lose a potential player, we've decided to reserve her as an NPC. Thanks though. ;.;
