I was looking at the three pictures for more details and noticed a few little things.
1) On the first blueprint, it says Lower Level. Does this mean the rumor of a two story house may be true after all?
2) On the same blueprint, the windows have bars covering them in a prison-like fashion. Maybe this backs up the prison house rumor.
3) As BriMan said, Shadow Creek sounds like a new location to me.
4) The image of the skull seems mummy-like to me. Maybe I'm over analyzing it. :shrug:
