it, causing an unforeseen backlash of energy that creates a black hole, threatening Earth. After being briefed on the situation by his old friend Major Vernon, former U.S. Navy SEAL Cutter Slade is given the job of escorting three scientists (William Kauffmann, Anthony Xue and Marion Wolfe) on a mission to this alien world to repair the probe and close the black hole. Arriving in Adelpha, Cutter is separated from the three scientists and, to his surprise, is hailed by the natives as their messiah, the Ulukai. The main population of Adelpha are a bipedal species called the Talan. Their technology is comparable to those of ancient China or medieval Europe, however they have psychic abilities that vary depending on each Talan's "essence": fire, earth, water, or spirit. Talan soldiers with the fae (fire) essence use energy weapons that are powered by their psychic abilities. Adelpha is split into several regions that are connected by a system of intercontinental portals known as daokas. These are relics of an ancient civilization, about which the Talan know little. At the time of Cutter's arrival the fire Talan have taken over society and rule through violence and intimidation. This is a relatively recent state of affairs; previously the Talan lived in harmony. As the game progresses, Cutter learns that the four members of the expedition were separated not in location, but in time. Marion arrives shortly after Cutter, but Kauffmann and Xue arrived decades earlier, and the original probe has not arrived yet. Upon learning of their predicament Xue became unstable, fell out with Kauffmann, and took over the Talan warrior caste, teaching them to be violent and xenophobic. This directly led to a Talan warrior attacking the probe on sight when it arrives, causing the creation of the black hole that threatens the Earth. Kauffmann realised that he could not stop Xue, and started the cult of the Ulukai among the non-warrior Talan before his death, preparing them to help Cutter when he arrives. Cutter weakens the warrior Talan and unites the other castes, and ultimately defeats Xue and his warriors. With Marion's help, he retrieves the lost computer cards needed to repair the probe. Marion is killed by Xue before the repairs can be completed. Following instructions left by Kauffmann, Cutter repairs the probe and strips down its internals so he can use it as a vehicle to return to Earth,
