You belong to Reach. Your body, your armor - all burned and turned to glass. Everything, except your courage. That, you gave to us. And with it, we can rebuild.
Halo - Reach
It didn't take long for Reach to fall. Our enemy was ruthless. Efficient. But they weren't nearly fast enough. For you had already passed the torch. And because of you, we found Halo, unlocked its secrets, shattered our enemy's resolve. Our victory - your victory - was so close... I wish you could have lived to see it.
Halo - Reach
Mankind is out-matched. When Reach falls - and it will fall - our annihilation is all but certain. Unless we can glean from this artifact a defense against the Covenant. A game-changer. On the level of the conical bullet in the nineteenth century, or faster-than-ligh travel in the twenty-third.
Halo - Reach
The Master Chief was enhanced and trained for one purpose. To win this war.
