We cannot come in time. With every hoof-beat of the relentless ride Sauron's visions haunt him, taunt him; the black ships, the white city burning. Though I drive the men and the horses into the very ground, and bring the host of the Dead at my back… how can we ever come in time?

At last, in utter darkness, they climb the black hill to the black stone.  Now I stake my claim; now must I hold them to their broken oath. And if I fail…

Dead eyes will see, though the night be as pitch.  "Hal? Unfurl my standard."
