Kretonians are a warmongering humanoid race first encountered in 2651 when the Vanguard scout vessel Gettysburg suffered an OS Drive malfunction and zoomed across the galaxy. On the return from Kretonian space, Gettysburg sparked the supernova of Kreton's star. Their world destroyed, the Kretonians embarked on a mission of destruction and conquest in late 2651. They ran roughshod over the Parallax, then the independent worlds of the Fringe, and finally in the Consortium. After killing or enslaving billions, the Kretonians were wiped out sometime in the 29th Century - either by human-created Specialist clone armies or by the Nall and their allies (depending on who you ask).
