[Hakon]

Also with Arthur and Aragorn you have the guiding figure. For Arthur it was Merlin and for Aragorn it was Elrond early on.

Also Numenor is similar to Atlantis. Both were like the ideal societies and both got sunk into the ocean. Both had a sort of divine ruler, for Atlantis it was Poseidon and for Numenor it was Elros.

The Battle of Helm's Deep is also comparable to Troy only in this case the roles are sort of reversed. The good is defending in this case rather than attacking.
