I want to fill either of these private storylines or any of the lines in my journal, but these two hold my specific interest right now.
I picked names for the sake of the description, they can be changed. I'll consider any of the roles. Potential psychological manipulation, potential gaslighting, body horror, involuntary surrogacy and ideally world building and involuntary surrogacy are all potentially present.
☆ tiny world ☆ Mason/Lloyd believed in magic when they were young, but as they grew older they grew up and stopped. Family members died and they found their life increasingly empty, filled only by work and occasional friends. It lead to them, on a night when they were too tired, thinking back to their made up adventures "I wish it all had been real."
Mason/Lloyd found themselves shrinking and suddenly being put into a small wooden cage, then flown out their opened window. A sprite kidnaps Mason/Lloyd, but it's anything but magical. They're put into the back of a wagon from the cage and there a tiny wyrm inside that attacks Mason/Lloyd, who passes out. The fairy Avalon/Lucan buys or saves Mason/Lloyd from the sprite and explains their predicament. The wyrm has gone into Mason/Lloyd's body and made its nest inside. The sprite had been planning to use Mason/Lloyd for wyrm breeding, a highly profitable venture. Mason/Lloyd has found a world of new adventure, but has to find a way to navigate the world of the tiny that they're now a part of while surviving the foreign creatures growing inside of them. ~~~ ☆ alien apocalypse ☆ Camille was at least 11 years old when the earth was invaded. Anyone between the ages of 17 and 65 disappeared without any explanation, leaving the young girl completely on her own. She finally found a place to settle in and feel safe, but it didn't work out. The aliens returned with plans for the remnants left on earth after 10 years. A mix of those left were chosen for hosts for the aliens' parasitic young, a circumstance that none of those who had been struggling to make it in the collapsed society could've predicted or prepared for. Similarly, a 21-year-old Camille never could've prepared herself for waking up one morning to realize she had been among those who had been picked for the doomed fate.
Carrying any of the alien young to term meant certain death, but no one knew how to get them out. It was as good as a death sentence. Camille had all but given up hope when she met Bridget/Raahi. Bridget/Raahi had been "adopted" by a retired doctor who was in their 70s when the invasion had happened and thus left behind. Bridget learned as much as they could from the good doc and was witness and assistant to the doc's less than ethical experimentation where the doctor figured out how to bring a surrogate to a state of delivery without dying. Once the doctor died, Bridget was left alone.
That's what lead to Bridget/Raahi deciding to take on another surrogate to try and perfect the process and potentially save the human race. (The idea of companionship didn't hurt either.) When they went to try and find someone, they found Camille. The unusual duo still have to band together and survive in this post-apocalyptic wasteland where people fend for themselves and do as they please.
