While Ylfon exists as a hand of the gods, once descended she must cherish the new savior more deeply than any other. For their sake, she will raise her symbolic pike for all the people of the world to see that a savior has come to guide them. Of course, faith is not something that can be forced. So Ylfon will bow in reverence to the new messiah, as an angle showing her devotion is what will ultimately inspire the people's belief.
