From my count, there are two votes, both Mint... who hasn't really seemed helpful, but more mischievous, given both Vera's and Remiel's state. I mean, Remiel can't even talk this round it seems! That's far from helpful (of which I think you said she claimed to have some helpful powers, Guy), so unless someone can convince me otherwise, This is my VOTE! I am voting for Mintprincess. If someone provides a better alternative, I'd be willing to change my vote.
As far as exploring goes... I'm in different. Since it seems with Sera's case, he was destined to die, I'm not sure they is actually any harm in it. But I'm not sure determined to explore the dungeon either, so if enough people wish to explore, I'll go along.
Though, now that I think about it, going back to Remiel... since he can't talk... he does still get a vote, yes?
