Homeworld Saga

Defeated at the moment victory was his, Satan has bided his time for almost two thousand years waiting for revenge. Now, for reasons only known to Him, Jehovah has allowed demons to affect the Earth directly once more. The Devil attempts three times to wipe out humanity on Earth. The first, by attempting to bring about the millennial heresy as an actual event. The second, by violating the First Law of Thermodynamics -- which states that all matter in the Universe is constant -- by bringing a whole planet from an entirely different Universe into Earth's Universe. The third, by invasion of an alien empire so malevolent and so technologically superior to Earth that the planet itself will cease to exist the moment the alien fleet arrives.
