What metaphors are used in A Dance with Dragons: A Song of Ice and Fire: Book Five by George R.R. Martin?

Example of Metaphor:

"'They're never far, you know. They won't come out by day, not when that old sun's shining, but don't think that means they went away. Shadows never go away. Might be you don't see them, but they're always clinging to your heels.'"
