The story revolves around Nikolai, apparently a part-cyborg; Galory, a young boy who apparently is part human/part Crest person, and Althea, who is entirely a Crest person. Seems the Earth and the Crest people were at war for 300 years so there are still a lot of bad feelings present. The ship Galory, Nikolai, and others are on is ambushed and almost everyone is killed by some kind of automated attack ship from a huge Crest ship that has been taken over by an automaton.
