Steampunk - Dystopia - The Vault Jigsaw Puzzle

There were only rumors that this room existed, no one believed it but I did. Rumors that spoke of inventions, treasures, and possibly even a murder. It took me years to find this place. However it was locked tight, some kind of antique yet quite sophisticated locking mechanism. I'm determined to get it open. The door is so close I can practically touch it. There must be something good behind that door, it's still a mystery. My mouth waters at the thought of what lies just beyond that door. Tools for world domination perhaps, maybe a vast trove of art or other treasures, could even be found alien tech.
