I had to open another security barrier, but past it found a cargo tube access and managed to push the sliding door open. A small passenger tube was still there. It hadn’t been used in a long time, long enough for the water and scattered trash on the carpet to combine and grow something squishy. I made my way up to the front compartment where the manual emergency controls were. There was still power in the batteries, though not much. It had been left here, forgotten, slowly dying in the darkness as the hours ticked away.
