    1 year ago

    Lé Na is an alien, identical to humans in looks, that was sent out to protect her from a supernova that destroyed her homeworld. Le Na was not the only Güdan sent out, just the only one sent out to Earth. For a near 1,000 years she traveled in her crystalline ship at the speed of light away from what humans know as the Crab Nebula, then maintained a holding pattern around the Earth until the onboard personality matrix deemed humanity advanced enough and progressive enough to accept its occupant's lesbian biological inclinations. Observe Lé Na as she adapts to life on Earth.

    A thousand years into the future, humanity has began to travel the stars. On ships of all makes and designs, they explore the great utter vastness that is space. Yet humanity is not what it once was, no. A thousand years ago, there was countless wars, argumentsm betrayals and . One day there was a massive war that where introduced was a virus that nearly killed the entire population of the planet. So the scientists worked day and night, spending years researching how to make the population grow again, and then managed it twenty-two years after the release of the virus. Hermaphrodites, futanari, dickgirls, newhalves, this was their solution: make everyone a single gender that can perpetuate the species should such a disaster ever happen again. Though many were resistant at first, but through the generations, it was accepted. The population bounded back and stabalised, science grew, spaceships made and now humans, nomads of space.
