In AT-43 [After Trauma: Year 43], humanity is at war with the technologically advanced Therians, a presumably robotic species bent on subjugating and transforming all planets for their ultimate purpose: the crafting of a "better", more organized universe under their rule, which they refer to as their "therian heaven". Humanity is seen by them as nothing more than pathetic, primitive animals. The center of mankind is the planet Ava, which came under attack by the Therians. The United Nations of Ava managed to push back the invaders, but bitter fighting left the planet in ruins. This pivotal event is referred to as the Trauma. 43 years later, the human forces launched a counterattack under the codename "Operation Damocles" on one of the Therian's factory Planets, the starting point for the AT-43 miniatures game.
Although the UNA and RedBlok will often be identified as the "human" race, this is not the truth. By reading the Therian back-story in their Armybook, you will find that it is actually the Therians who are the Human Race. The Therians hail from the Solar System SOL, which is located towards the tip of a spiral arm in the Milky Way Galaxy, and originate from the Third planet from the Sun. The Therians home planet was reconstructed by the Therians into a dyson sphere covering the sun long ago. Having become virtually immortal by re-engineering their own bodies, the Therians have been engineering the universe itself to prevent it from collapsing into a Big Crunch, a trillion years in the future, thereby insuring their eternal longevity. The Therians had predicted that without their intervention, the end of the Universe is inevitable, and that life will cease to exist in the future. Because of their all-encompassing view of existence, they see the only way to maintain existence is to destroy all known forms of planets and life and transform them into their type of travelling homeworld. To other races who do not share their same point of view, the Therians idea seems like the destruction of life itself, when ironically it is actually the permanent preservation of life. Most races will resist the Therians because they will fail to see their end-goal, and will put up resistance. Even though there are Races like the UNA who are powerful enough to temporarily disrupt the plans of the Therians, there are none who can hold them off for good. In the end, the Therians will either have their way or life will cease to exist when the Universe comes to an eventual halt.
Besides the external threat of the Therians, humanity is still fighting against each other: The Red Blok, a revolutionary faction with communist ideals, is at odds with the United Nations of Ava. The Red Blok started as an uprising on Ava's manufacturing planet Hades, and manifested itself into a political movement. At first the political opposition was crushed by the armed forces from Ava, but as the Avans started to think that the threat was subsided, the Red Blok managed to convince the planetary troops that their ideals were a better way of life. The Defense force later joined forces with the struggling workers that they were assigned to subdue, and after a violent rebellion they created their own formal government. After the formation of the Red Blok, Ava lost its main production facilities, and the political movement spread throughout the planets under Avan control. The Red Blok is now a major threat to the Avan ways of life. Even though the Red Blok and the U.N.A. are allied in their efforts against the Therian threat, they are by no means on friendly terms. The bitter taste left between the two sides has led to disastrous un-cooperation, and communication failures. There is still a deep underlying distrust between the two sides, and as time goes on these feelings only burn deeper and deeper.
An alien race with as yet unknown motives are the Karmans, highly evolved, sentient apes from the planet Karma. The Karmans originally allied with the Therians when they first attacked Ava. The Karmans, like most races in the galaxy, owe their technological achievements to the ancient knowledge passed down through Therian relics left behind on their planet. Now that they see the massing army of the Therians, and that no one can escape their threat, the Karmans return to Ava to fight with Humanity to take on the omnivorous threat of the Therians. The Karmans do not want the balance of the universe destroyed, and though they have no allegiance to the humans, they see it fit to keep them around for the benefit of the galaxy. Not much is known about them yet, but concept art and a preview miniature show that they are a highly evolved Ape-like species that uses their technology to amplify their strength.[1]After the release of the Official Rulebook more information has been provided regarding the Karman. We should see an official release in Q4 2007 with more information regarding the Karmans.
