I, too, would like to see Norse mythology in the show.

What appears to be Mjolnir was seen in Rumple's estate and Asgard has been mentioned. But Disney hasn't really used Norse myths to my knowledge

If they were to feature Hades or Hel, I'd say it'd be more likely that we see Hades, who is also a Disney character.
