How many characters does that make it? And here I thought it was gonna be a nicely packed, small roleplay. Jeez, things will be pretty crazy the first few days, weeks even. 
Good luck, GM.

[@Ghost Queen] And I agree, winning or losing is not important to a narrative. It's about how the characters develop and come to a greater understanding of something, the 'combat' simply being the method. A fun one at that, I'll admit.
