For centuries this are was virtually always a warzone, with numerous tribes vying for control of decaying Ugandan cities and the vital Lake Victoria. As part of his humanitarian mission, Colin Kintobor, Sr., father of Julian Kintobor and son of Gerald, sent soldiers, money and technology to the area, roping off a large chunk of the region for his "humanitarian experiment."
His plan was to create a utopia from scratch in the area, free from war, disease, famine, and the corrupting influences of many societies. He hoped that, upon succeeding, he could build replica societies all over the world for the betterment of sentientkind.
However, he also had to administer Shikoku, so had a radical experiment performed to ensure effective leadership. He was able to, through methods he took to his grave, upload the dying Gerald Kintobor's consciousness into a harddrive, and this became the basis of the GKaDOS, Gerald Kintobor and Disc Operating System.
While GKaDOS did his job well, possessing Gerald's sound mind and personality, things quickly went wrong. As digital technology began to sprout up all across the area, his true colors came out, the kind and altruistic Gerald replaced by a mechanical sociopath. Natioanlity, ethnicity, color, etc. all became irrelevant, with GKaDOS rechristening himself GRaDOS and forcefully dividing all people into BLU or RED forces. He made sure to often do so between families to make them enemies. Most inhabitants found collars placed upon them to kill them if they went against GRaDOS' will.
GRaDOS, contrary to what some assumed, did not pursue war abroad. Instead, he was more focused on making his subjects kill eachother in elaborate ways, supposedly for scientific research. Watching bands of RED and BLU align for some reason or another only to backstab (sometimes literally) eachother was far too entertaining to pass up.
GRaDOS eventually grew bored of this, however, and so came up with a novel idea: spreading discord and war to other countries. With a nation that ate, slept and breathed war, he was ready to export his hardened veterans overseas. While overseas, "Test Subjects" were not to discuss internal politics or pursue them, RED and BLU forces working together as "VLT" forces.
With a massive, imposing wall surrounding the bulk of VLT's borders, and the wealth the company has made off mercenary forces, GRaDOS' rule over the country is virtually unchallenged.
