make whatever modifications or interventions they deem appropriate. These Hosts have been documented on Earth, and have also been found on many other planets throughout the universe. Other major examples include the Skrull homeworld, hundreds of millions of years ago, and numerous Sh'iar worlds, such as Gladiator's homeworld. First Host on Earth Collecting a number of natives during the Stone Age, they then begin genetic experimentation to determine the species' future development. They create two subspecies from the natives: Eternals, Deviants, and a majority "normal" strain that may or may not be modified in some manner that enhances its long-term development. For example, the Celestials first visited Earth nearly a million years ago and implanted a special genetic code into the early hominids. This implanted DNA structure has been revealed to be not only the source of the ability of select random humans to develop superpowers upon exposure to dangerous environmental catalysts, it also allowed for the development of benevolent mutations that caused the existence of inborn potential superpowers in mutants. In truth, the Celestials came to Earth to investigate the disappearance of a Celestial only to realize Earth might eventually create antibodies against the Horde infection via its powered inhabitants. Second Host Approximately 21,000 years ago, the Celestials returned to Earth for the Second Host and found that the Deviants had created a vast empire across the world based on the continent of Lemuria, where they had conquered most of the primitive human tribes with their superior technology. They were also about to go to war with the original human inhabitants of the neighboring continent of Atlantis. The Celestials then destroyed Lemuria and sank it under the ocean, utterly shattering the Deviants' empire and indirectly sinking Atlantis-therefore destroying both continents and reshaping the Earth. Third and Fourth Host Resenting the presence of the Celestials and their monitoring of Earth's progress, the Skyfather figures of Earth (e.g. Odin, Zeus) attempted to stop the Third Host, but were quickly outmatched. The Space Gods then informed they would return 1,000 years later to judge Earth's right to continue existing. The Skyfathers then developed a convoluted plan to stop the Fourth Host via the use of the Odinsword and Destroyer armour, but once again the Celestials prevented the offensive and melted the Destroyer armour into slag, scattering the Asgardians' life forces. The Earthmothers (such as Frigga and Hera) of Earth, however, had planned
