but it makes much more sense that there is an ancient warg who has evaded death through the millennia by just taking over a new person every hundred or so years. so that same ancient "spirit" for lack of a better word couldve done everything, and bran is just his new vessel

i like that MUCH more than bran just somehow gaining knowledge from the trees or whatever

because it brings a new player into the game entirely

It's basically GOTs deus ex machina
