Black Tower

200px|right Black Tower is a song included in the Halo 3: Original Soundtrack. It plays during the level The Covenant, and is the second movement of the Covenant Suite. Also, when you play it in reverse, you can hear a message from Gravemind. It's related to T.S. Elliots' poem, The Hollow Men.

I am very sure I have figured out what the message in this song says. Here it is. "Eyes from death's dream kingdom appear as sunlight on a broken column. There, in death's other kingdom, walking alone, trembling lips form prayers to broken stone."

It runs for 6 minutes and 3.702 seconds (6:03.702).
