You awaken in the sealed basement of the lab where you had been frozen. It's dark, and empty. Not at all what you had expected upon the ending of your stasis. There were supposed to be scientists here, to end the cryo state, check your vitals -- welcome you back! Maybe even some reporters to interview the person from the past.
Instead, just empty darkness, lit only by the light of your cryo pod. Tentatively you got out, hugging yourself. It was only a little chilly, but you were naked. The room still seemed like you remembered it -- white walls and floor, nothing present except for your pod and the monitoring equipment. Everything was dusty though. Very dusty.
Looking closer, you see that the monitoring equipment is also on. There is a very faint hum coming from it, and some text displayed faintly on the screen. You walk over, shivering as your bare feet contact the cold tile floor.
"Minimum power setting due to electrical grid failure," the monitor reads. "Emergency generators 1 and 3 active." Below that it says.
"Limit for manual awakening cycle exceeded. Automatic awakening cycle... complete.
If you are reading this, then an emergency has occured and no staff remain at this facility. Please use the emergency supplies stored down the hall. Good luck."
Another shiver runs through you, this time of fear. What happened? Am I the only person left...? Dear God, that can't be...!
You exit the room, leaving the door open so that the light from your pod can illumine the hallway outside. There are dim red emergency lights lining the top of the wall, but only one is lit, and it is flickering. You do, however, see some other rooms along the hall, as well as a door to your right, with its own bulb illuminating a sign reading "Supply;" and to your left, a massive pair of pneumatically sealed bunker doors.
You check all the rooms, but they just contain abandoned lab equipment, air recyclers, and the generators. For a moment, still a bit groggy, you had hoped to find other cryo pods, but then your emembered that the participants had been spread across different facilities in case of an apocalypse scenario. You never seriously thought that that would turn out to be a necessary precaution.
Finally you go to the Supply room. It's sealed by a wheel crank, but fortunately you are able to turn it without issue and open the door. Inside is a large combination of walk-in closet and pantry. There are some clothes in your size; canned food; bottled water; a hefty backpack; a flashlight; a pocketknife. There appear to be some items mssing though -- from the mount you'd guess one of them to have been a shotgun or rifle.
There's also a large freezer. Opening it you see a selection of food, mostly fruits and vegetables. However, what truly catches your eye is a note taped to the inside of the door. Outfitting the flashlight with some batteries, you examine the note. At first you think it was written by two different people, as an elegant, flowing cursive alternates with more restrained, professional script. But as you read it a stomach-turning realization settles on you.
"Hello darling!
I am leaving you this note as some form of explanation. Already my mind is being opened to just what I can do, and I'm very tempted to take you out of that silly pod and add you to my harem. However, enough of my sanity remains that I will leave you be. Two centuries have passed since your hibernation began, and you still have one more to go before the system will wake you automatically.
Perhaps by then I will have conquered the world -- or things will have returned to normal, though that seems laughable. Humanity cannot resist the power of the 'monster girls,' as we have been dubbed. It began a few months ago -- about 1 in 10 people underwent a beautiful metamorphosis from boring human to beautiful, magical creature, feminine in form but with varying genitalia. Data is scarce, though I myself am one of those blessed with both cock and pussy.
Ugh, my remaining humanit prudishness hates how vulgar my new persona is... As you can see, this change -- cause still unidentified, though the popular notion of 'magic' seems as good as any -- affects the mind as well as the body. As the change progresses, we lose our absurd scruples, allowing us to take full advantage of our powers to play with the hapless mortals that remain unchanged.
I have to go. As much as I am curious to see a human from the past awaken in a world we control, the temptation to just enthrall you now will soon be too much. For your sake, I will direct my 'new interests' towards my colleagues and leave you safely sealed with these supplies. Good luck, and I'll see you in a hundred years, darling.~
Dr. Marvin Fielding Vinamara, the Succubus Queen"
With trembling hands you set about assembling a pack, deeply unnerved by what you've just read. It would be impossible to believe, except that something obviously happened and this is the only clue you have. So, as far-fetched as it sounds... you have no choice but to at least entertain the possibility of its truth.
All too soon you have your supplies secured in your backpack, knife and city map tucked in the pocket of your new clothes and flashlight in hand. You take a moment to gaze at yourself in a mirror, gaudy and out-of-place in the utilitarian setting. A gift from the Succubus Queen? you wonder with a shiver. At any rate, you are glad of the chance to examine your appearance, and reflect on what you remember of your past life before agreeing to the cryo experiment.
