Digimon Frontier

The Digital World of Digimon Frontier is divided into ten regions, each one representative of one of the world's ten elements - Flame, Light, Ice, Wind, Thunder, Earth, Wood, Water, Steel and Darkness. A massive network of train tracks criss-cross the planet, with a terminal in each region, allowing the train-like Digimon, the Trailmon, to ferry passengers from one region to the next. The most distinguishing feature of this Digital World is the existence of "Fractal Code" - the "command code" for the data that forms the Digital World, possessed by everything, from individual Digimon to masses of land. Fractal Code is usually hidden, but once it is uncovered, it can be "digitized," which in turn "unlocks" the data of the item or individual in question, allowing it to be manipulated. In most cases, this leads to the data being absorbed - an action frequently perpetrated by the villains of the series. Conversely, if the Fractal Code is "rendered," it restores the data to its intended shape and form and "locks" it back into place. If a Digimon has their Fractal Code scanned, but their data is not absorbed, then it will reconfigure itself into a Digi-Egg, which then transports itself to the Village of Beginnings, where, after being tended by Swanmon, it will hatch out into a new Baby Digimon and start its life over again.

In ancient times, the Digital World was wracked by a massive war between the human-type and beast-type Digimon. It was then that the angel Digimon, Lucemon, appeared and brought the war to an end, leading to a period of peace. Lucemon, however, eventually grew corrupted, becoming a tyrannical ruler, prompting the emergence of ten great Legendary Warriors who embodied the ten elements. After a mighty battle, the ten Legndary Warriors were able to defeat Lucemon and imprisoned him in the "Dark Area" deep within the center of the Digital World.

Passing on into the realm of legend themselves and leaving powerful "spirits" embodying their elements behind, the ten warriors were succeeded by a trinity of angelic Digimon known as the "Celestial Digimon" - Seraphimon, Ophanimon and Cherubimon. The group was not a harmonious one, unfortunately - the beast-type Cherubimon disagreed with many of the human-type Seraphimon and Ophanimon's policies, and made the argument one of the beast versus human. Mistakenly believing that the two human-types planned to betray him, the despairing Cherubimon found himself overtaken by the dark aura of Lucemon, and was transformed into a virus form. The evil Cherubimon then led the beast-type Digimon in a campaign against the human types, ultimately capturing Ophanimon and forcing Seraphimon into a regenerative coma.

To save the Digital World, Ophanimon called upon children from Earth to merge with the spirits of the Legendary Warriors and become Digimon themselves to help free Cherubimon from Lucemon's influence. The new Legendary Warriors were eventually successful in freeing Cherubimon, but Lucemon, undeterred, soon had enough power to consume the fractal code of the entire Digital World and destroy its moons, and then began to plan his conquest of Earth as well. In the last battle to save what remained of both worlds, the Legendary Warriors defeated Lucemon and the Digital World, and the Digimon on it, were restored.

This particular Digital World is also orbited by three Digital Moons, each named after the world's three rulers, and each one a different color - the blue Seraphimoon, the yellow Ophanimoon and the red Cherubimoon. At least two of the Digital Moons are inhabited, the Seraphimoon having a population of Starmon, Meteormon, and Burgermon, in their various Digivolutionary forms/stages. The Ophanimoon, surrounded by hazy clouds of yellow dust, is home to a Rebirth Village (similar to the Village of Beginnings in the Digital World), where new Digimon are hatched from Digi-Eggs and Digimon whose data have been destroyed can be reborn and reprogrammed as new Digi-Eggs.
