A few small problems with what you say here:

I know that magic and spells play a role in its forging, but in GoT chapter 72, Daenerys X, it says that Valyrian steel, is possibly forged with dragons.

Some theories say it dragon blood?

I know that not all Starks have the same capacity for warging, but the Stark children are all wargs. But only Bran is also a greenseer, right? Jon can become one in the books? I read this theory about Ghost probably being one. I can go mad reading all theories. lol

Speaking about the NK greenseer vs Bran greenseer, we were speaking a couple of days ago.

“Bran: You’re a greenseer.
Jojen: No, only a boy who dreams. The greenseers were more than that. They were wargs as well, as you are, and the greatest of them could wear the skins of any beast that flies or swims or crawls, and could look through the eyes of the weirwoods as well, and see the truth that lies beneath the world.”

So most def. NK is a the most powerful greenseer. Instead of reducing Bran to a plot device for bs, why on earth the show didn’t concentrate on him this season about this issue? It seems to me that this is Bran’s purpose. All those people, Summer included, didn’t die to protect him just to tell Sansa and Arya what LF did.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
