Moria: Legolas' point of view
Boom, boom, boom, boom, drums in the dark depths sound out among us, risen by the foolishness of young Peregrin Took. My enhanced hearing can pick up something as foul as darkness and fire, yet more evil than Sauron. The dreary drums come closer, closer, closer.
Silence.
The calm before the storm. We draw our weapons, my brilliant bow shines out above them in anticipation, my fingers itch to reach up and draw the arrows that will fell many a foul orc. Waiting, waiting, waiting.
Silence.
Something's not right. I look to find Gandalf, to inquire about the fleeing orcs, and I see him standing all alone on the bridge, a beacon of light in this dark tomb.
Silence.
Suddenly, a great roar fills the vast depths of Moria, and along with the cry comes fear, fear like I have never known. It is as if my body is consumed by cold and evil. Oh no. A balrog. We must run…
Boom, boom, boom.
