Imperium

Imperium means power.

Since my teenage years, I have enjoyed the Dune franchise of Frank Herbert—the literature and movies. The setting is many thousands of years into the future, as humankind has expanded throughout the galaxy. The official language of the Imperium is called Galach, a descendant of Earth's English, Russian, and other languages. Meanwhile, on the desert planet Arrakis, the Fremen eke a living as desert people. The Fremen language is a descendant of Earth's Arabic.

Religion in future outer space is a subject of some sci-fi. The Dune franchise is a great example. Frank Herbert created the thousands-of-years-from-now Dune series, focusing on an Arab-like culture and language group of the Fremen on the desert planet Arrakis in a galactic imperium in which the language Galach is spoken, a derivative of ancient English and Slavic languages. I have read another book, The Jesus Incident, by Frank Herbert and Bill Ransom, about a spaceship that is like a god to its human crew, looking to colonize another planet.
