Fan:Digital World Genesis

Age of Chaos
The Ancient Digital World was ruled by Pharaohmon, a powerful sovereign who had control of many Digital areas. On the other hand, it was an age of chaos, being devastated by beings such as Orochimon and Sangloupmon. In this era, the Digital World was salvaged by the intervention of mighty Digimon such as the heroic Imperialdramon or the Holy Digimon Shakkoumon. When Lucemon, the first-born child of God rebelled against his Father, he was exiled to the Dark Area together with another six apostate Digimon. Upon the excommunication of Lucemon, his three gifts were embodied into the Celestial Digimon.

Mythic Age
Lucemon begins his strike upon the Digital World. Nevertheless, the Ten Legendary Warriors unite their strengths in order to defeat the evil leader in his apostasy outrage. In this era, Yggdrasill has assembled the pantheon named the Royal Knights, led by Imperialdramon. Olympos XII was another pantheon assembled in this era which bears a rivalry towards the Royal Knights. A remnant of this era is the Eastern Digital World, guarded by the Divine Shakamon and his servant Ravemon, where also lies the Golden Land, once reached by the mythic Gokuwmon upon completing the Threefold Trials proposed by Yatakaramon.

The Digital World's God
Obviously, there would have to be a deity responsible to the Digital World's creation. There are two possibilities. Huanglongmon, the leader of the Four Sovereigns, despite of having been sealed by Lucemon (proof that Lucemon's might rivals the gods'). Or Yggdrasill, which is more obvious, due to Shakamon, from the Eastern Digital World, being closest to Yggdrasill (allusion to Shakyamuni, patron of the Buddhism), and due to Valdrmon, a Bird Digimon existant since the creation of the Digital World, who has the same mythic background as Yggdrasill. The most exact theory about the Digital World's God is that He resides in the Digital World's Kernel.

Evolutionary Tree of Mythic Digimon
Obviously, the Mythic Digimon have pre-evolutions that probably originated their races or spawned from them. Otherwise, some Digimon did not de-digivolve, but have turned to weaker guises after the end of the Mythic Age, such as Imperialdramon changing from Paladin Mode to Dragon Mode (and later back to his Fighter Mode). These are the remnants of the Digital World pantheons.

Holy Wars
The Seven Great Demon Lords and the Seven Swords of Virtue/Royal Knights have been at war with each other for eons. Lucemon fused together with his compatriots in order to become Ogudomon. An intangible being, it was not phased by any of the DigiHeroes' attacks, until the Young Paladins had to enlist the Delphi Priests in order to cast the Ten Legendary Warriors, who merged into Susanoomon and the latter destabilized Ogudomon for good. After this battle, there was the cataclysm that ended the ancient Digital World era.
