a baleful light, flame more than light, flared from his eyes.
"What it was could not be seen: it was like a great shadow, in the middle of which was a dark form, of man-shape maybe, yet greater; and a power and terror seemed to be in it and to go before it.... The dark figure streaming with fire raced towards them .... and the shadow about it reached out like two vast wings. It raised the whip, and the thongs whined and cracked. Fire came from its nostrils. But Gandalf stood firm. `You cannot pass,' he said. The orcs stood still, and a dead silence fell. `I am a servant of the Secret Fire, wielder of the flame of Anor. You cannot pass. The dark fire will not avail you, flame of Udûn. Go back to the Shadow! You cannot pass.' The Balrog made no answer. The fire in it seemed to die, but the darkness grew."
(JRR Tolkien, "The Lord of the Rings: The Fellowship of the Ring"
