I think it's more likely that the Dragon civil war did happen in the past, but the maybe the present is the cause.

The story Zirconis' soul told was about a single Dragon coming up with the idea that Humans should be treated as equals. Maybe one of the Dragons who came to the present will be so impressed by the Humans in the present that he'll go back in time and become that first spark for the civil war, most likely without knowing that it'll kill most of his race.
