as the moments run together
It is dark, and it is cold, and you know neither where you are nor where you are going.
Somewhere behind you (far, far behind you) is the place where you awoke, but you had to abandon that after Tammy's death. Maybe that wasn't entirely rational, maybe you should have waited for ... for command to send assistance or to otherwise contact you, but you couldn't just sit there alone with her corpse.
At first, with your flashlight playing over glass walls and cyclopean gulfs, it seemed reasonable. You could only remember bits and pieces, but you thought that you at least knew the way to open sky. The trucks were useless, with no gasoline in the tanks or the cans (how could that have been allowed to happen?), but you had a light and you had food, and you didn't think it was more than a couple days' easy march.
But your flashlight died before the first day was out - your batteries all seemed old and weak, and they didn't last nearly as long as they should have. You've been walking with one hand on the cold glass wall, skipping openings and staying to the main passage ... if your memory can be trusted (can it?), that's the right thing to do.
Your fingers slide along glass, smooth and endless, and you can feel the vastness of the passage like a brooding pressure, stretching out above, behind, ahead. You are cold enough for gradual misery, if not cold enough to freeze and eventually die of it. And the darkness plays tricks on you. You think you see things, and ghost sounds come to you out of imagination and memory.
Memory blurs with fantasy, in the dark. Is there really a light somewhere up ahead? Did you really wake hours (days?) ago in an alien spaceship? Is Tammy Jackson, your friend, really dead? When you sleep, you dream of walking through darkness, and when you walk, you seem to dream. You might be going mad, Ronnie.
Roll+cool to act under fire, with the fire being near-total sensory deprivation. On a 10+, you keep it together just long enough to reach light. On a 7-9, you freak out a bit, and you misplace something important to you in the darkness (what?). On a miss, you cannot trust any your memories of anything since waking from stasis, and you take psi-harm as soon as you see non-imaginary light (roll the psi-harm).
Also, roll+sharp for your beginning of session move, as your memories blur together with hallucinations.
