Voiceless it cries, Wingless flutters, toothless bites, Mouthless mutters. — J. R. R. Tolkien

It cannot be seen, cannot be felt,

Cannot be heard, cannot be smelt.

It lies behind stars and under hills,

And empty holes it fills.

It comes first and follows after,

Ends life, kills laughter.

The king is come unto his hall

Under the Mountain dark and tall.

The Worm of Dread is slain and dead,

And ever so our foes shall fall!

To say that Bilbo's breath was taken away is no description at all. There are no words left to express his staggerment, since Men changed the language that they learned of elves in the days when all the world was wonderful.
