This AU stems from the idea that Nai never caused the Great Fall, and Project SEEDS went on without consequence. However, instead of settling down on a planet, they ended up remaining on the ships for the next 150 years.

As Nai and Vash grow up, others are awoken from cryo-stasis, since the cold sleep method to keep the body alive begins to result in neurological degeneration without explanation if it goes on for too long. Proper civilization emerges on the ships as a result.

William Conrad eventually leaked the information of Tesla's experiments to the public in a bid to prevent it from happening to the Plant Twins. Ultimately, the experiments were voted to be unethical by the majority, and the scientists responsible were imprisoned for it. This is the biggest reason as for why Nai never initiates the Great Fall.

As of the present, Rem is biologically 89, while chronologically around 150 years old. She's getting close to the end of her life, and is preparing Vash and Nai for her own passing.

Nicholas D. Wolfwood volunteered for an experiment to fix the imperfect method for degeneration in cryo-stasis. However, he is accidentally sent through a forced cellular aging period, and now looks 30 when he's closer to 18-19 years old. He is then inducted into the Eye of Micheal, a religion that worships Plants as gods and led by Legato Bluesummers.
