Game of Thrones is a retelling of the Norse myth of Ragnarok.
Bran is the wolf (Stark’s sigil) Fenir, son of shapeshifter Loki (Three eyed Raven), who is bound (crippled) by Tyr (Jamie Lannister) who loses his right hand. Fenir’s wild and unpredictable brother (in the weirwood network) Gamr (Night King) and Tyr (Jamie) end up killing each other.
Lannisters are the good guys, and Starks are the bad guys.
Thanks for bringing that up! I need to go and re-read that!
