"In one universe, humanity had a religion that worshipped beauty as a god. It was only a minor religion for the first part of that world's history, but it had a huge revival around the time of their technological revolution. They were fortunate enough to live in a solar system with several habitable planets. The members of this religion had the belief that it's easier to create new beauty than it is to fix what isn't beautiful. So, their religious leader led the colonization of the first new planet. Only the truly devote went. Everything was a work of art, everything. They converted more followers, and led the colonization of several more worlds. Eventually, humanity stretched across that universe, and most of the worlds were colonized by this religion. It's spectacular. I can't put it into words. Every world became more beautiful than the last."
