They groped their way down a long flight of steps, and then looked back; but they could see nothing, except high above them the faint glimmer of the wizard's staff. He seemed to be still standing on guard by the closed door. Frodo breathed heavily and leaned against Sam, who put his arms about him. They stood peering up the stairs into the darkness. Frodo thought he could hear the voice of Gandalf above, muttering words that ran down the sloping roof with a sighing echo. He could not catch what was said. The walls seemed to be trembling.

'A Balrog,' muttered Gandalf. 'Now I understand.' He faltered and leaned heavily on his staff. 'What an evil fortune! And I am already weary.'
