George R. R. Martin Iron Quotations

Robert was the true steel. Stannis is pure iron, black and hard and strong, yes, but brittle, the way iron gets. He'll break before he bends. And Renly, that one, he's copper, bright and shiny, pretty to look at but not worth all that much at the end of the day.

So be it. I'll wear my iron and hold my tongue. A man who won't listen can't hear.

You can't hammer tin into iron, no matter how hard you beat it, but that doesn't mean it's useless.
