Scandinavian mythology included dwarves, elves, and the Norns, who distributed fates to mortals. The ancient Scandinavians also believed in personal spirits, such as Fylgja and the Hamingja, which in some respects resembled the Christian idea of the soul. The gods were originally conceived as a
confederation of two formerly warring divine tribes, the Aesir and the Vanir. Odin was the leader of the Aesir and Njoror was the leader of the Vanir. These two tribes consisted of 12 gods each.
There were Nine worlds which where all held in Yggdrasil (the world tree).
