Ho! Tom Bombadil, Tom Bombadilo! By water, wood and hill, by reed and willow, By fire, sun and moon, harken… — J. R. R. Tolkien

We must take a hard road, a road unforeseen. There lies our hope, if hope it be. To walk into peril – to Mordor. We must send the Ring to the Fire.

It is perilous to study too deeply the arts of the Enemy, for good or for ill. But such falls and betrayals, alas, have happened before.

'Faithless is he that says farewell when the road darkens,' said Gimli.

'Maybe,' said Elrond, 'but let him not vow to walk in the dark, who has not seen the nightfall.'

'Yet sworn word may strengthen quaking heart,' said Gimli.

'Or break it,' said Elrond.
