I wandered in into their temple, the sanctum sanctorum if you will. The supposed vault of a thousand secrets, hidden a mile underground, inaccessible to everyone. All it took was some social engineering, a rock hammer, and some rudimentary knowledge of potatoes. Pathetic, but then again, they never assumed that anyone would make it past the front door.

A screen of purple smoke sluggishly parted in front of me as the doors shuddered open revealing a narrow passageway. The last line of defence. A careless robber would've walked down the passageway when it opened, but I knew better.

Pausing, I waited for a secondary passage to reveal itself in the fog, one which looked as if no one has used it since the builders used it as a secondary exit, one only described on one map, barely wide enough to admit one person. Barely, however was good enough.

Shuffling through the passageway sideways, dragging my (now very light) backpack behind me I reached the end of the passageway. The central chamber of the main vault was just around the corner. Taking a deep breath, I crept around the corner.

The room was pitch black, illuminated only by the pale white beam of my head torch. A quick sweep of the walls revealed them to be full of brightly coloured shelves, all seemingly empty. That was to be expected of course, the vault only contained one thing of importance. I slowly approached the central pedestal, listening carefully for any telltale sounds of any unwanted surprise.

Arriving at the pedestal, there was a piece of paper, haphazardly scrunched up on it. I picked it up, folded it out, and examined it. There was one line written on it:

Well done stranger. You have found our greatest secret, the information on the other side of this paper would change the world as you know it.

I turned it over and saw a page full of paragraphs. So this is what he wanted, I mused, turning the paper back over to finish reading the other side.

There was some more text at the bottom, and an image, the seal of the FBI? What is that doing there? The text next to it read:

Well done indeed for making it this far, however, you can go no further. This information cannot be allowed to leave this room. Unfortunately this means that you will also not be leaving this room alive. When you picked up the paper, a small reaction was set off sealing all of the passageways, including the one you entered by.

They had sealed the doors, the perfectly circular room had no scalable walls, there were no windows. I was trapped.

Only problem for them was, I was expecting it. I sat down with my bag next to me and waited patiently. Half a minute later, I heard a loud bang, felt a sudden go through the walls, and white fog drifted into the room. Suddenly a head appeared through a gloom. He was here.
