Ok, so I was able to get a little information over night that gives us a little bit of insight, though there are still many questions that could be asked. I was trying for win conditions, but I wasn't able to get colour information and win condition information and SOV was nice enough to still give me information on one of them.
There are wolf and non-wolf classifications. Each has a colour. The non-wolf classifications are: The Arrow's circle, regular villager, ambiguous villager, criminal and neutral.
So wolves are in this game. As to how the criminals fit into this, I don't know, but I am wondering about the recruitment of them. Like Cyndia said, the main bad guys usually don't like to get their hands dirty. Usually.
Anyway, that is why I was so stressed yesterday. I wanted to make sure I could get us some information on what is going on. Unfortunately, it's not a whole lot.
