Quick note!
On the white and blue side, the person carrying Ievan is actually his adult self. Since the adult form has suffered some pretty drastic things, he managed to learn an anthem that'll allow him to help his current form and still keep his daughter, Selina, safe. He only appears when the real form is in critical danger (like the other side of the picture. See if you can guess who's grabbing him!) He doesn't want the same tragidies to happen again.
