Into the Barrier Peaks

Hraefn
Scanning around, you see no other exits besides the one you came through in the south door. However, your eyes spot a small opening covered by a small panel in the ceiling. You can feel a very faint breeze blowing through it. A ventilation pipe of some form, it seems.

The golems leave you to yourselves, and as they depart you move quickly into action. You slip, apparently unnoticed, up into the vent. You find youself inside of a dark, 1-inch diameter pipe, that connects to a maze of piping in the ceiling.

Hraefn was relieved that the golems did not detect him. With the rest of the party in the cells, waiting for a commandant that may or may not arrive any time soon, Hraefn went about surveying the holding room very carefully. He tried to note exactly how the cell barriers were operated, looked at any other controls in the room, equipment storage, etc. They had some time, so he intended to be thorough.

You instantly shrink to the form of a small wasp and escape up into the ventilation pipe above your cell. Moving south, you see that the golems remain mostly in the main chamber, with one of them routinely (every few minutes) exiting through a door to the south. This door has a plain, metal panel that the golem presses, which causes the door to slide open.

There is another room to the south, this one void of golems but with incredibly strange and alien equipment (laptops) sitting atop a desk made of the same material you have seen broken and lying about the hallways. (i.e. plastic, aluminum, etc.). From this southern room, the golem approaches a red door to the east, where it produces a piece of red leaded glass, perhaps 1.5 inches wide by 3 inches long. It slides the glass into the slot of the door and the door slides open. The glass then falls into a small catch chute where the golem retrieves it and returns it to someplace inside its armor plating. What is in the room to the east cannot be seen, as the door closes and there is no vent leading in that direction. The golem is gone for perhaps 2-3 minutes before it returns through the same red door.

The process repeats itself with other golems going through the door as the previous golem returns.

Hraefn
The room appears much like an office, perhaps once belonging to someone who commanded the golems? Or a senior golem, if that were possible? The working of the door seems easy enough, though it would seem you need a colored glass key that matches the same color of the door panel (in this case, red). Plain, metal panels without color simply require you to touch the panel and the door opens.

Inside the red door is another, smaller (interior) hallway. At the north end is a red door, and in the middle and south are a pair of gray doors, and the south hallway ends in yet a third gray door. The golem slides slowly along until it reaches the north. It opens the red door, and stands there, apparently looking into the room beyond for a moment. The door slides closed, and the golem returns. While you do not get a chance to thoroughly examine the second room, it appears to be a storeroom of some kind, containing boxes and crates of all shapes and sizes.

Not sure if it's possible to take a short rest while pacing restlessly, but that's my plan.

Unfortunately, the only door cards you have seen are inside the golems.

Bram
As Bram gets closer to the open entry of the cell he is in, the rivets lining the archway begin to flicker and hum. Suddenly, pale rays of light criss-cross the open space of the arch.
