War, war never changes...
When the Great War began nuclear bombs reined across all nations and engulfed the world in flames. Those who were lucky obeyed the warning sirens and fled into great underground bunkers to protect people from the nuclear holocaust called "Vaults" and waited out the events of the bomb's effects.
When the vaults opened the people that had survived spread out into the wastes if they wanted and started to begin life anew. Some formed factions and tried to unite areas of the former world under their banner. Some became powerful, some didn't, but one such powerful group was created in the Great Lakes Region in the lower peninsula of Michigan. They emerged from Vault 55 near Saginaw and started to spread. They called themselves the Michigan Federacy, they believed in the old United States government basis but had differing views on the branches of government and so made their own little unique system and started to go into the wastes. The new faction founded towns, raided pre-war buildings and bunkers, and taken over smaller factions bringing them under their wings. After years of growing influence and good leadership they had a government, a strong military, plenty of raided armor, guns, energy weapons, some power armor, food and drink supplies, loyal citizens, and a strong hold on the entire Michigan lower peninsula, northern parts or Indiana and Ohio, and the southern peninsula of Canada that borders Michigan.
Things couldn't look better for the Michigan Federacy but terrible leadership crippled the Federacy and it lost ground and power. It was a state of sadness for those who had invested in the Federacy but it was bliss for the smaller factions the Federacy had crushed in their campaigns for land.
The year was 2287, six years after the Second Battle of Hoover Dam. A new President was elected for the Federacy, his name was Nick Aleius and immediately his goals were to bring the Michigan Federacy back to it's former glory and go even further than before. He was an incredibly successful man and because of the Michigan Federacy's belief of a constant serving president until retirement or government removal he and the people planed for him to serve for a long time. He reclaimed the lost territories and spread to northern parts of Canada, he then decided to spread his faction's influence northwest. He launched the military to the former upper peninsula of the Michigan region of the Midwestern Commonwealth. He planed to only meet smaller factions that he could conquer but at the midway point of the peninsula the Michigan Federacy met with the Enclave Remnants.
The Remnants had been rebuilding themselves since their defeats in California and Washington DC. They had gotten stronger because of no pursuers and was planning on revenge against the Brotherhood of Steel. However the two sides eventually went to war after several bad diplomacy meetings based on territory. The war has been going on since 2289.
The year is 2291, the war continues on, The Michigan Federacy and The Enclave have been at constant conflict. Smaller factions with power or without plot and scheme to grasp lands for their own but neither big faction can put too much attention to them because of the war. The wasteland is as dangerous but lately rumors have spread that north or all these territory hungry factions in parts of Canada, it is better, still dangerous, but better. However, because of the war both The Michigan Federacy and The Enclave are paranoid of spies getting out of the borders looking for help so they have tried to seal their borders off.
You are a prisoner in the Wisconsin wastes in an Enclave prisoners, your fellow cellmates talk of rebellion against the guards, they think they have a perfect plan. As much as your doubt it's flawlessness this could be your only chance out of the metal bars you reside behind.
