So far so good. The cat has helped keep the critters away, so I've conserved ammunition, and we're all stocked up on supplies. For the immediate future, I'd say we're safe and secure.
Further than "immediate" though? I'm not so sure. Neither of us are builders, and there are bigger, tougher animals than long-toothed cats out there. Eventually we'll need to find some new friends. Nosti was the biggest settlement in the desert, but it couldn't have been the only one.
I'd heard rumors that a hunting party had seen some buildings to the west. Sounds like as good a place to start as any.
