Shape Shifting

When a runic shape appears on the side of Halvar's face, Urobe convinces everyone that he has been visited by the Gods, and soon the whole village thinks that he has the power to take the shape of any animal or person. Halvar disappears, and a duck takes his place as captain of the ship. To avoid disaster, Vic has to pretend to be Halvar, and restore his father to his rightful position of captain.
