I tried to fit the already-defined OS Domain and OS Problem into here. I think it worked out pretty well. Note you have to read to the end to see the Moonlighting gist.
Overall Story Catalyst: Moonlighting (
Colony Director Lena (Antagonist) knows there is more to sustaining a colony of survivors than simply giving birth to the next generation. The human race needs a Minimum Viable Population to survive: a big enough gene pool, and enough people to do the work required to survive. What is the point of reviving Clay? Even if he is able to impregnate the women, the next generation will be one of half-brothers and half-sisters, an unacceptable gene pool. Now is the time to be reaching out and finding other survivors, uniting with other colonies. Not wasting their few resources on getting a few women pregnant and raising children.
So on top of their normal job of caring for themselves and the colony, she orders that everyone must "moonlight" -- do the additional work to prepare for and sustain constant expeditions to bring in other survivors. This extra work accelerates the tensions in the colony, pushing the conflict between Fertiles and Infertiles to a head.
Meanwhile, Director Lena herself moonlights as a sperm bank caretaker. While she couldn't keep the cryogenically-preserved people like Clay a secret, she was able to hide the facility's perfectly viable sperm bank. It will be useful one day, but for now, no one can find out, since to use it would be a huge drain on the colony's resources. But this "side gig" adds a lot of strain for her, so whenever anyone notices this, or tries to dig into her secret, it accelerates conflict and pushes the story forward.
