Nation of Fire and Iron:
Human: Humanity's bearings as the last race of Homo Sapien fled to the sandy areas the Orcs called home. The Orcs didn't kindly take them in at first, but then realized the potential the Humans had as a tiebreaker in their war with the Nation of Water and Dirt.
Orc: After being in war with the Elves for so long, the Orcs retreated back into their deserts for years.
Nation of Air and Coal:
Dwarf: The Dwarven dug deep and sealed themselves away from the rest of the world due to madness. From that point were they forgotten until recently, the gnomes who resided near their lands called to the deeps, and awoke the last dwarves to assist their defense against the Nation of Earth and Brimstone.
Gnomes: Peaceful, but short tempered little people who reside in the hills. Recently the Dark Orcs have been attacking their homes.
Nation of Water and Dirt:
Elf: The Elven people sought peace and life, and those around them destroyed land to create. Angered by this, they lashed out against the other nations and quickly became enemies with everyone.
The Marine: An unknown man from an unknown time. He woke up in the Elven Forests, and was quickly taken captive.
Nation of Earth and Brimstone:
Dark Orcs: A race of Orcs that decided to live in the Great Fire Swamps. They were enslaved by Low Elves, who use them as brute force in their plan to take over the world.
Low Elves: A race of elves who were exiled for ideas against the Elven Forest. They seek to conquer the planet.
