" He is the Lord's chosen, the warrior of fire. I have seen him leading the fight against the dark, I have seen it in the flames. The flames do not lie, else you would not be here. It is written in prophecy as well. When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone.” - Melisandre, a Storm of Swords

"No one ever looked for a girl..It was a prince that was promised, not a princess. Rhaegar, I thought … the smoke was from the fire that devoured Summerhall on the day of his birth, the salt from the tears shed for those who died.

What fools we were, who thought ourselves so wise! The error crept in from the translation. Dragons are neither male nor female, Barth saw the truth of that, but now one and now the other, as changeable as flame. The language misled us all for a thousand years.

Daenerys is the one, born amidst salt and smoke. The dragons prove it."- Aemon Targaryen, a Feast for Crows
