Family planning

Your sister-wives both slept peacefully next to you, but you still found yourself awake and contemplative. This was the toughest decision you had made yet... Keep the tribe as just the three of you and populate Eden as a new Adam and Eve and Lilith? Or recruit more women so that you don't have to wait generations before starting to build a community? You'd kind of hoped that one of the wandering groups of women would find you by chance and make the decision for you, but that was just wishful thinking. As the tribe founder, you needed to be decisive.

A seed of an idea started to form, like a dream, as sleep approached. The long conversations about friends in your father's tribe drifted in and out of thought and mixed with memories of the old world. There were others there, too, even if you and your siblings were all generally closer with each other than any of them. Your friends from that life were scattered across the continent, probably the world, but it didn't have to be that way...

In your dreamlike state you fall backwards into your godly powers and embrace them like never before. At once you see many former friends of you and your sisters, at least the ones you were acquainted with. Everyone is healthier and more attractive, their best features enhanced, and the men are all now women but still recognizable. With a great pull history changes and your father's tribe swells as your friends' mothers retroactively join it. One by one these friends were born into your father's tribe as your half-sisters, growing up alongside you and each forging a friendship with the three of you based on your relationship in the old world.

Then, you became an adult and left to found your own tribe. These friends all decided together that since their world was changing too with the loss of their only male friend, and all being newly adults themselves, it was time for them to start a new chapter in their lives as well and set out to find a new tribe to join. This group wandered the continent, never finding another tribe... until, guided by visions, they found themselves in the valley of Eden. Though it was empty, they knew it was where they belonged, so they settled down to wait for the day that a tribe would discover Eden and allow them to join.

That tribe is yours, and the day is not far off. You and your sisters camp closer to the valley every day, their pregnancies not slowing them at all. Your divine powers fade and you suddenly feel very tired, not from exertion but from having the burden of that decision finally lifted from your shoulders. Satisfied, you return to spooning your wives and allow yourself to drift off fully to sleep.
