In 2007, scientists discovered a parallel universe. The U.S. government sent a probe to that universe and learned of the existence of an entire alien civilization there. However, an apparently hostile alien damages the probe, leading to the creation of a black hole threatening the very existence of our own world. Former U.S. Navy S.E.A.L. Cutter Slade is assigned to escort three scientists to the parallel universe in an attempt to repair the probe and avert the danger. Upon arrival, Cutter is separated from the scientists and is greeted by the local inhabitants, the Talan. It appears that their world, Adelpha, has its own troubles: a mysterious being known as Faé Rhan has been assembling an army consisting of Talans who think themselves superior to the rest of the population and are willing to rule over them with violence. Cutter is proclaimed the Ulukai, a savior mentioned in a prophecy, and entrusted with the task of retrieving five sacred relics needed to overthrow Faé Rhan - all while trying to locate the scientists and save the Earth as well in the process.
