"So he journeyed by night up into the highlands, and he found a little cave out of which the dark stream ran; and he wormed his way like a maggot into the heart of the hills, and vanished out of all knowledge. The Ring went into the shadows with him, and even the maker, when his power had begun to grow again, could learn nothing of it." - J.R.R. Tolkien, 'The Lord of the Rings', Book I, CH. 2, 'The Shadow of the Past'
