How does the Viking series universe expand upon traditional Norse mythology?

The popular TV series Vikings is loosely based on Norse mythology and has expanded the traditional mythology in many ways. One of the most notable expansions is the portrayal of the lead character Ragnar Lothbrok, who is not mentioned in traditional Norse mythology but is believed to be a combination of different legendary figures.

The series also takes liberties with the portrayal of the gods, such as the depiction of the god Odin as a physical presence in some scenes. The series also features some storylines and characters that are not found in traditional Norse mythology, such as the character of Floki, who is a creation of the series.

Overall, the series has helped to popularize Norse mythology and bring it to a wider audience. While the show may not be completely faithful to the traditional myths, it has created an interesting and engaging universe that has captured the imaginations of many viewers.
