All I can say is that according to CC, Lavos never even rose. Chronopolis has no information on Lavos, and assumes that they exist because something caused Lavos to dissapear, allowed the future to progress. In other words, Lavos could not have ripped out of the ground, otherwise Chronopolis would have information. The only info they do have is the one from the Dead Sea (the conglomeration of timelines) and their own parallel worlds analysis scenario thingy.
