You decide to head inside

You take a few cautious steps forward, your boots crunching on debris.

As you move deeper inside, you notice signs of former people. Footprints in the dust. A bottle or two here and there. And dark stains on the floor that look suspiciously like dried, human blood, possibly extracted not long ago.

At the far end, you find a heavy wooden door. It's tucked suspiciously deep inside, a back room of sorts.
