What do you suppose happened to Nettles and Sheepstealer after they left Maidenpool? At the end of the Dance she would have been the last dragonrider left in the known world if she was still alive.On a related note, any guesses as to the fate of the Cannibal?

Well, as to Nettles, we do have some idea:

“Amongst the Burned Men, a youth must give some part of his body to the fire to prove his courage before he can be deemed a man. This practice might have originated in the years after the Dance of the Dragons, some maesters believe, when an offshoot clan of the Painted Dogs were said to have worshipped a fire-witch in the mountains, sending their boys to bring her gifts and risk the flames of the dragon she commanded to prove their manhood.”

So Nettles became a goddess, and Timmett son of Timmett might be her descendant.

As for Cannibal, there’s no mentions of its potential location after the Dance.
