I'm Natasha. By my count, there are at least a few dozen of us who found ourselves here yesterday. Many of us gathered at the lighthouse last night and I think we need to coordinate our efforts to explore and determine what supplies we have available.
Dr. Snow mentioned setting up an infirmary area. Eliot suggested exploring nearby buildings and potential food sources. I think it might also be a good idea for us to set up some kind of security watch system since we have no idea what we're dealing with and the letter implied there are threats we could face.
So that's food, shelter, medical, and security. What else do we need to do?
