Mafia 100. Sylvan: Tree of Life.

I have no idea who he could be. Arets did a good job, he created intrigue, that's for sure.

Although, I can't associate the word "duty" with the Mafia. It seems to fit Lizard the best, as he's kind of on duty, guarding at night. But I'm not completely sure about anything anymore, so I'd like to hear other opinions.
