Its only a theory that WHite Fatalis was the reason Scrade was destroyed as in game and by Capcom most of the info about him is blank. But Capcom did say he is able to summon any origin dragons meaning the other Fatalis and Dire Mirallis making him a leader sorta. It is possible that he may have lead a full Scrade city invasion since in game and by Capcom says no one actually knows how the city instantly lost contact. But to me, I get the feeling this is pushing the White Fatalis invasion idea especially since it was already said Crimson can be found in the castle also. This makes all 3.
