A mysterious, ancient-looking gate appeared in Washington, D.C., sometime in the 21st century. From the gate poured out monsters, knights from medieval Europe, and other fantasy-like beings, and they began a systematic slaughter of the citizens of the U.S. capital, laying siege to the White House. For the first time since the War of 1812, the streets of the United States became a battlefield. Due to their unrestrained arrogance, the Empire of Sadera immediately sought to claim the lands on the other side of the gate. However, they would soon realize just how inferior their own military truly was. Once the U.S. military mobilized, they attacked the invaders with their advanced technology, forcing only a thousand of them to retreat while killing or capturing the rest. This unprovoked attack on U.S. soil, not seen since September 11th, 2001, would be known as the "Washington Incident." In retaliation, the U.S. government sends the United States Marine Corps to the alternate world beyond the gate, thus beginning the American-Saderan War. We will follow certain groups of people from both the nations of Earth and the kingdoms of Falmart to set the stage for the bloodiest conflict Falmart has ever seen.

Due to all of this the nation made a series of reforms that were woefully needed to make their country better such as standing neutral in most conflicts unless they are provoked and making reparations to any trouble caused by any rouge element that stemmed from their nation however being neutral doesn't mean they will not have a strong military force, not to invade another country's land but to protect their own. By 2020 they have rebuilt their name, there may have been several bumps while they did but they atoned for their past and the future seems bright for them. However several days after the 25th anniversary of the end of the Belkan war, the nation of Belka suddenly vanished
