Re: In the Shadow of the Mushroom Cloud
The team quickly slithered through the hole in what was once a solid wall of avalanche debris. This avalanche had covered an enormous entrance (large enough to admit a submarine, anyways) that was once underwater. Then the seabed rose due to seismic activity, and further seismic activity some time after had collapsed the cliff face above it, blocking it off.
Clearly a small gap had been recently enlarged by hand by the removal of several boulders and digging out soil. It was unclear who had done this, Sea Otter's people or the Krell and their mercenaries. Tim, in the lead, checked for traps and tripwires before squeezing through the gap and found nothing.
Outside there had been enough ambient light for their NVGs to work. Once inside there was absolutely no light at all, forcing them to use their IR-filtered hand torches (flashlights) to provide enough illumination for them to work.
They found themselves at the end of a vast, long underground chamber. Beams from their flashlights played over an enormous screw and rudder looming above them. The massive submarine to which they belonged stretched away into the blackness. From the configuration of the running gear and various faded paint markings they could tell right away it was an American submarine. Likely an Ohio-class "Boomer" (SSBN).
But they couldn't see much else standing on the bottom of a dry sub pen with the hull looming above them. They were on the left side of the bottom of the dry sub pen and the sub was heeled over to starboard. Likely settling that way when the water drained away and dried up after the local sea level subsided. The dry bottom around them was lightly littered with debris (chunks of ferro-concrete from the roof, snapped mooring lines, cables, etc.) More cables/mooring lines dangled down the wall on both sides.
To their left were metal rungs of a ladder set into the wall. They lead up to the pen's deck level, 15m above them. From where they were they could pretty much see the submarine's stern looming above them and not much else.
PD Note: There is so little light that to see anything at all, you need to use your IR-filtered flashlights.
