The United States of the Atlantic

In General
The United States of the Atlantic is a democratic nation that is based in the former states of North and South Carolina. Its capital is based in the city of Queensdom, formerly known as Charlotte, in the Northern half of the Republic. Following the lead of the former United States, the new USA is divided into 12 counties, the most important being that of the two Crown counties, Queen (Queensdom) and King (Kingston). In recent years, the USA became divided over the issue of the enslavement of Ghouls, culminating in King County and five other states seceding from the union and shelling a Queen's Fort in Kingston. Altogether, the wastelands are known as the Crown Wasteland.

On That Fateful Day
The fates of Charlotte and Charleston were very different, unfortunately.

In Charlotte, many of the citizens were paranoid. As such, the Mayor of the city had made a deal with Vault-Tec, requesting that they create large, temporary shelters for the people all around the city, along with the necessary Vaults. These Charlotte Shelters were only designed to last a few months or years, at most, so that the people would be able to leave as soon as possible.

When the President made his announcement of the nuclear strikes, people flocked to the Charlotte Shelters, enabling a large amount of people to survive the nuclear attack. Nearly 80,000 people made it into the shelters before the first bombs hit, along with those in the Vaults, making the nuclear attack on Charlotte a failure, in comparison to the others.

Only three bombs were dropped on Charlotte and the surrounding area, so the area wasn't as heavily irradiated as many other cities in the US. When the citizens were released, they began to use Vault-Tec methods to find ways to rid the area of radiation, or at least speed up the removal of them. Due to their sheer numbers, the citizens were able to found a lasting civilization and begin to extend their influence outside of the city...

Charleston, however, was a different story. The only vault was built inside Fort Sumter, a slightly inaccessible area. Thus, few people were able to get inside the vault before the bombs hit. Only about three hundred people survived the explosions in Charleston, and these survivors soon degraded into lawlessness and barbarism. The Vault survivors believed themselves superior to the ghouls, so they quickly enslaved their irradiated counterparts, forming a lawless civilization of their own.

Soon, the nations collided and Queensdom invaded Charleston, taking over the city. However, slavery was too deeply rooted in Charleston's society to be so easily removed, and thus ghoul slavery continued.

The Nation of Queensdom soon reformed into the United States of the Atlantic, renaming Charleston into 'Kingston' and making it the capital of the southern half of their nation, although Queensdom was still superior.
