Xenu ( ), also called Xemu, is a figure in the Church of Scientology's secret "Advanced Technology", an esoteric teaching held sacred by adherents. According to the "Technology", Xenu was the extraterrestrial ruler of a "Galactic Confederacy" who brought billions of his people to Earth (then known as "Teegeeack") in a DC-8-like spacecraft 75 million years ago, stacked them around volcanoes, and killed them with hydrogen bombs. Official Scientology scriptures hold that the thetans (immortal spirits) of these aliens adhere to humans, causing spiritual harm.
