Sounds like Hearts of Space muzak... nice
There is one theory that suggests that Ragnarok was a set of real events. You can explore to your hearts content at : https://www.thunderbolts.info/wp/

The age when Kronos/Saturn(no known name for Saturn in Norse, their major God was Odin/Woden or Hermes in Greek Mercury in Latin)

In those days Kronos ruled the sky but then was disposed by Zeus(aka Jupiter/Thor)
and Gandalf was a wandering one-eyed wizard, apparently he was the planet Mercury

Good luck...
