After the death of Eli Vance, Gordon, Alyx, and Dog go to the Borealis to destroy the hazardous cargo, but what is not known is that, all this time, the Borealis was in a slow dimensional flux which is what caused it to vanish in the first place. The trio meets Barney Calhoun on the Borealis as he saw the transmission sent by Judith Mossman. The Borealis goes into a flux while all four are on it and are sent to a parallel dimension along with the Borealis. They arrive in a world of floating islands; some civilized, some not, but the population are all anthropomorphic canines and felines. A canine hunter and his two female companions befriend the four, but because of the dimensional flux, a force the people of the islands thought was gone returns and threatens their world once again. Even worse is that the time between each dimensional flux has decreased on the Borealis, and the Lambda resisters have to choose between saving this dimension or getting back to their own.
