Combine

"We should thank Our Benefactors for giving us respite from this overpowering force. They have thrown a switch and exorcised our demons in a single stroke. They have given us the strength we never could have summoned to overcome this compulsion. They have given us purpose. They have turned our eyes toward the stars."

- Wallace Breen adressing citizens’ concern about the Combine negating human reproduction.
