"Human beings are vile, nasty creatures.
Blood thirsty.
Evil by their very nature.
That is was we were told. By them.
Humans relished for millennia in systematically destroying one another. Our innate yearning for violence lead to not only the destruction of ourselves, but of our planet.
Our home.
Our planet was dead, our species nearly extinct, so we left. Those who survived dreamed of finding a new planet, a safe haven where we could start over. But our technology was failing and we never made it to our destination. We were adrift in space. Destined to die in the emptiness of the universe. It was luck that the Morrí heard the signal broadcasting. It was altruism that they came to our aid. It was their generosity that provided a home and a life for the remaining humans.
They were our saviors. Without the Morrí, the last of humankind would have perished along with a broken vessel.
That, at least, was the version of history we were taught. Humans had to earn their place among the Morrí. Humans must prove themselves. Humans are not to be trusted due to our volatile nature. Humans owed their very existence to their Morrí superiors."

Keep your head down and survive.
Don't attract the attention of our Saviors.
