Arden
Blackwing Lair Raider
I've got another theory. I think Martin got distracted with other storylines and put the wights on the back burner. He started the books with the intent on making the White Walkers a big part of the series, but then found out he liked writing about other stuff more. Let's face it-- the inter-house political drama and history stuff is more interesting than the tired storyline of "a great evil comes down from the north and threatens all civilization." I'm sure he isn't going to totally drop the wight storyline, but, frankly, I think the series has outgrown it.IDK man. It seems apparent they don't operate on the timescale of Men. I would bet its a case of Blue and Orange morality or something like that. Years later they haven't attacked the wall?
Why didn't they attack 7000 years ago a millenia after they lost the first War for the Dawn?
This seems to be a theme with Martin anyway. He's an excellent writer, but even the best writers get tired of certain storylines and lose focus. That's where his editor is supposed to come in and say, "Hey man, you keep going off on tangents and losing the main thread of this story. How about you put these ideas into side novels, or short stories, or prequels, or sequels, or whatever, and just focus on keeping a cogent storyline."
