"Then Aragorn led the way, and such was the strength of his will in that hour that all the Dunedain and their horses followed him. And indeed the love that the horses of the Rangers bore for their riders was so great that they were willing to face even the terror of the Door, if their masters' hearts were steady as they walked beside them. But Arod, the horse of Rohan, refused the way, and he stood sweating and trembling in a fear that was grievous to see. Then Legolas laid his hands on his eyes and sang some words that went soft in the gloom, until he suffered himself to be led, and Legolas passed in."
