Cortana (COM): "One moment, sir. Accessing the Covenant Battlenet. (Pause) According to the data in their networks, the ring has some kind of deep religious significance. If I'm analyzing this correctly, they believe that Halo is some kind of weapon. One with vast, unimaginable power."
Captain Keyes: "And it's true
The Covenant kept saying that whoever controls Halo controls the fate of the universe."
Cortana (COM): "Now I see
I have intercepted a number of messages about a Covenant search team, scouting for a "control room". I thought they were looking for the bridge of a cruiser that I damaged during the battle above the ring. But they must be looking for Halo's control room."
Captain Keyes: "That's bad news. If Halo is a weapon, and the Covenant gain control of it, they'll use it against us and wipe out the entire human race."
