Jormungand
Captain of the royal guard and one of the few soldiers King Leonhart actually trusts. He started out as a regular soldier from some small country and basically worked his way to the top, which honestly says something about his competence. Best known for his no-nonsense attitude—he can't stand sloppy or half-finished work, which probably explains why Leonhart keeps him around.
He's close friends with Leonhart, which isn't surprising given how much the king seems to rely on him. On the romantic side, Princess Amit of Murga has a crush on him, though that's kind of a one-sided situation.
