What will the myths be in A Song of Ice and Fire?

By the end of A Storm of Swords and the beginning of A Feast for Crows (which I just recently began rereading. I’m almost at A Dance!) Jaime’s transformation is roughly complete and Sansa has begun the next phase of becoming a major player of the game of thrones. (Warning, spoilers up to the beginning of A Feast ahead). Given that both Sansa and Jaime are nobility —and high nobility at that I think it’s fair to say eventually songs will be made about their lives and their histories will shift into  exaggerated legend like so much of the available history of Westeros and Essos in general.

Look at Ser Duncan the Tall. In the novellas he’s a modest knight at best, his fighting skill is more streetbrawling than proper knightly combat. Somehow though his story changes into something much more dignified. At one point Jamie wonders how he could possibly measure up to Ser Duncan as Lord Commander:

“The chair behind the table was old black oak, with cushions of blanched cowhide, the leather worn thin. Worn by the bony arse of Barristan the Bold and Ser Gerold Hightower before him, by Prince Aemon the Dragonknight, Ser Ryan Redwyne, and the Demon of Darry, by Ser Duncan the Tall and the Pale Griffin Alyn Connington. How could the Kingslayer belong in such exalted company?”

Obviously good fortune finally falls onto Dunk but from that passage I get the sense that it’s more than that. It sounds like Dunk’s entire life is exalted.That’s a pretty big change for someone who in his early days of knighthood thought about how “…he had beggars blood himself…or so they used to tell him back in Flea Bottom, when they weren’t telling him that he was sure to hang.”

So at the end of one of the last Jaime p.o.v. chapters this passage encouraged my curiosity about what the future retellings of some of the characters will be:

“When he was done, more than three-quarters of his page still remained to be filled between the gold lion on the crimson shield on top and the blank whie shield at the bottom. Ser Gerold Hightower had begun his history, and Ser Barristan Selmy had continued it, but the rest Jaime Lannister would need to write for himself. He could write whatever he chose, henceforth.
Whatever he chose…”

What will Jaime’s history be? And moreover what will the conventional wisdom of Jaime’s history be? Not necessarily the truth mind you, but what people think happened to Jaime Lannister. Where I am now in the books, it’s really hard to tell.

That’s less true with Sansa but true nonetheless. She’s clearly going to live her life as a courtier and nobility. That’s how Martin shows us that world in Westeros. Littlefinger even says as much:

“Remember that, Sansa, when you come to play the game.”
“What…what game?”
“The only game. The game of thrones.”

So we know Sansa’s going to be some kind of major player eventually. What will the stories of her marriage to Tyrion be? What about her abduction by Littlefinger?

I want to put this out to you dear readers: What will the stories of some of these characters (currently alive or dead) be?
