The two ships had collided as one had a severe navigational error and the other had been stolen by a youth who wanted to go out for a joyride. They crashed together on a planet that, for both of them, was just barely habitable. The surviving humans called out to the other ship and found it to be filled with Nox who were even younger than the human youths who were barely into their teens. Despite a rocky start, the two groups begin to work together to survive the ordeal. By the time rescue comes to take the kids back to their homes, the teens, once barely getting along, were good friends. After all, it's hard to avoid becoming friends when putting aside differences and working together was the only way to survive. -- DaniAndShali
Given the Human book called Lord of the Flies, the rescue crews didn't expect to find the surviving Human teens nor any surviving Nox younglings in any kind of good condition. In fact, given Human Media on the topic, they expected to only find sad remains.
They never expected to find a fully-functioning proto-society with a kind of improvised daycare for the Nox built in the remains of the ship, with passable structures for the rest and shelter of the young Humans. Together, the young Humans had created work-arounds for everything they needed given everything they already had. This, despite the fact that the logs in the wreckage indicated that half the young Humans were at the throats of the other half.
Yet, there they were, working together to farm, raise animals, and create tools, clothing, and shelter for all. Certainly, there was an invisible line of demarcation where one alliance was a definite distance from the other, but all Humans and some Nox were crossing that line in a calm and relaxed manner by the time the rescuers came. There were no lingering signs of violence, though there may have been some signs of pranking. All in all, the village was incredibly well-thought out.
