Artemis fowl and fallout series the modern version

Prologue

Eighty years ago a war raged between the human race, country went to war with country. It was world war three a war that the world had hoped to avoid. People weren't ready for the outcome, they knew that there was a possibility of nuclear warfare but they hoped that it would not happen. During the war Europe and Australia allied themselves to America and Canada to fight the Communists in the east. The war began the moment North Korea took over the south, the South Korean government pleaded the American government to support them and so they did. They send there best forces into Vietnam once more. But this time China were ready for the war and they offered their support to the North Koreans and send in wave after wave of their soldier through Korea and the American forces were soon wiped out just on the first wave.

The American government were shocked by China's actions and asked the British for their assistance and they agreed to stand beside their American comrades once more. Even though the people of Russia were fighting one another they also joined the fight and fought for the Motherland against the US and the British. The world noticed the war on a catastrophe scale and before they know it they also got dragged into the fight.

The Allied nations knew that if Korea, China and Russia thought all was lost they would destroy them with their nukes, so they got all of there best Scientists and engineers together to create something that would protect the people of their countries as well as themselves and it was known as the vault. The vault went against a series of tests to see whether it could with stand the nuclear attacks and it did. The allied nations began to build the vaults all over the countries and placed the greatest minds inside as well as their families and then they devised a lottery in which people would be chosen to stay in the vaults and they would stay inside until the vaults computer system would open the vault and allow them to go back into the outside world. But that was not the only things that the allies made they also made an invention that was known as project purity. The scientist developed the schematics and tested a prototype that could purify the world and make it like it was before or better even.

But there was something that the Communists and the Allies weren't expecting that never side would win the war. They both launched nuclear missiles at one another and destroyed each others countries. But both sides still survived because of the vaults, they weren't completely destroyed and never were the fairy race that lived underground. They themselves tried to prevent the war by sabotaging the nuclear bombs and taking out political leader but it did nothing the war still continued and all the people could do was sit and watch as humanity destroyed the surface that they had waited impatiently to retake.
