Long ago this world was purged in darkness. No Royal Knights or Tamers fought to protect us. Our end was inevitable. Until, from the ashes rose four valiant soldiers who shall forever be known as, The Riders.
Binary castle stood tall in the night, watching over the whole of the Digital World. Inside stood rows upon rows of ancient terminals storing copies of every digital monster. Guarding the terminals were some of the most well-trained holy Digimon in the entire Digital World. Underground, beneath the Digimon, beneath the terminals, beneath the entire castle lay an ancient tomb under the eternal watch of four large statues.
The all-powerful Olympus XII had begun to fall to an unknown threat. Entire cities lay in ruins within hours. This threat was later known as the Nimda occurrence. A single Digimon with five different forms, all of them deadly. The Riders fought each form of Nimda and eventually defeated the threat.
A shadow entered unseen through the gates of Binary castle and into the corridors. As the watch shifts changed the shadow was able to slip into the terminal room. The shadow approached the furthest terminal and moved it aside to reveal a passageway. Upon entering the passageway the terminal was replaced over the entrance to prevent unwanted followers. As the shadow reached the passageway it looked around to find four ancient statues.
Upon the defeat of Nimda The Riders worked alongside the surviving Digimon to rebuild the Digital World. The White Rider built a village to house the reborn Digimon who had fallen to the hand of Nimda. The Red Rider built a tower that reached the heavens, stocked with arms and armor to provide training to the defenseless. The Pale Rider built a town to house all who were outcast or discarded by the remaining societies. The Black Rider built a fountain whose waters could rejuvenate and heal the weary or diseased. Afterwards they worked together and built a massive castle with information on every Digimon who had ever lived, and it served as their final domain.
The ground shook and the night erupted in flame as the Binary castle began to crumble. Angemons could be seen fighting fiercely against something in the fires but they were soon all turned to data. The air was filled with screams of agony as unseen forces cut down warrior after warrior. Binary castle was left in ruins and from the fires stood four horsemen, each with a purpose. Each with a gear.
