Daenerys Targaryen Quotes

Handmaiden: A trader from Quarth told me that Dragons come from the moon.
Daenerys Targaryen: The moon?
Handmaiden: He told me the moon was an egg, khaleesi. That once there were two moons in the sky, but one wandered too close to the sun and it cracked from the heat. Out of it poured a thousand thousand dragons and they drank the sun’s fire.

He was no dragon. Fire cannot kill a dragon.

Dany

Game of Thrones Quotes

I will hurt you for this. A day will come when you think you are safe and happy, and your joy will turn to ashes in your mouth. And you will know the debt is paid.

Tyrion Lannister

Oh, my sweet summer child! What do you know about fear? Fear is for the winter, when the snows fall a hundred feet deep; fear is for the Long Night, when the sun hides for years and children are born and live and die all in darkness. That is the time for fear, my little Lord.
