This is a song I love because I’m a Norse pagan and to see people making music about it is great.I’m not sure whitch myth this song refers too but it sounds like The Twilight Of The Gods because Frenir gets loose and swallows Odin and the Viking ship that never comes back is a good one but then it says in Óðins Hall which after that event would no longer exist.Those are my thoughts on this song. Hail The Gods and Goddess of the North
