At the end of the first battle scene with Ragnar and Rollo standing in the field, Ragnar sees an old man walking among the dead. The old man is the god Odin, who was said to be a shapeshifter, able to alter his form in any way he liked. Odin was said to travel the world mostly as a one-eyed, grey-bearded old man with a staff, wearing a wide-brimmed hat and a traveling coat.
