Well i only mentioned that theory because Ddraig and Albion didn't even remember why they started fighting, they might not even remember most of the things they did in the past, well there are many legendary beast/creatures that are unknown yet. So i just give the possibility that Ddraig and Albion once fought against some extremely powerful beast but they forgot about it.
