Dialogue
In Darkness, David Scully, who voices Avery J. Johnson and many of the Sangheili, speaks in a deep voice and says:

"I had a dream... But it was not all a dream. The bright sun was extinguished, and the stars did wander darkly in the eternal space. Reignless, pathless, the icy earth swung blind and blackening in the moonless air. Morn came, and went, and came... and brought no day, and men forgot their passions in their dread. All earth was but one thought, and that was death..."

- Quoting George Byron
