The sun sets. As the moon grows brighter, the living grow quieter. The next day repeats the same pattern. You get nervous. You find an abandoned warehouse on the edge of a deserted street. You walk in wondering what's inside. You go to the back, find a switch, push it, and a hidden door appears. You walk through, and nobody ever saw you again...except...the one's who used to rule these very ruins...
