Board Thread:Magnus Chase & the Gods of Asgard/@comment-25044056-20151022144432

For a while it's been my understanding that In RR's world gods are basically the embodiments of the cultures that created them and have a symbiotic connection to that civilization. The Olympians for instance are still around because western civilization is still around. Supposedly if western civilization were to decline the Greco-Roman gods would weaken and they could fade if western civilization were destroyed.

By that logic however, why are the Norse gods still around?
