The Fire Nation, Dubbed during the War as the Great Fire Nation, is one of Xuiz Earth's four nations and four sovereign states. It is an absolute monarchy led by the Fire Lord and home to most firebenders. Geographically, the nation is located along the planet's equator in the western hemisphere and is composed of several islands. Its capital is simply known as the Fire Nation Capital. The Fire Nation is the second-largest nation in terms of area, following the Earth Kingdom, while its economy is the most powerful in the world; its strong industrial sector and extensive technological developments not only enabled the Fire Nation to create an extremely powerful military, but also initiated the worldwide modernization and globalization, leading to it being the strongest and most advanced country in the planet when the Axis discovered the planet in 1514 NE.
Before the Axis discovery in 1514, the Fire Nation was in the midst of a century-long war with the rest of the planet that was sparked in 1430 by the Fire Nation when it carried out a genocide against the Air Nomads, in an attempt to kill the newest Avatar, and proceed to invade the rest of the planet. In over those near hundred years worth of warfare and conquest, the Fire Nation managed to gain control of significate chunks of the Earth Kingdom and made repeated raids against the Water Tribes before being aided in turn by the Axis, namely, the Combines and Germans, in the remaining decades, which in turn, saw the Earth Kingdom and Water Tribes being aided by the Alliance, dragging the planet into yet another front of a much larger and much more destructive war.
But this new-found alliance between it and the Axis would not last for long. In 1529, the Avatar, an Airbender named Aang, was released from his icy prison and over the year, managed to gain allies and companions to finish his training and put an end to the war that has ravaged the planet, though sit backs did occur, like the Conquest of Ba Sing Se and the failed Invasion of the Home Islands, ultimately, then Firelord Ozai was overthrown and his son, Zuko, was named Firelord, who promptly switched sides and joined the Alliance, ending the Hundred Year War, but not the Campaign on Xuiz, which continued for decades to come.
