“GLORFINDEL: His pace is light and smooth; and if danger presses too near, he will bear you away with a speed that even the black steeds of the enemy cannot rival.
FRODO: No, he will not! I shall not ride him, if I am to be carried off to Rivendell or anywhere else, leaving my friends behind in danger.”
–J.R.R. Tolkien (The Lord of the Rings: The Fellowship of the Ring)
