Krycek: Hear this, Agent Mulder... listen very carefully because what I'm telling you is deadly serious. There is a war raging, and unless you pull your head out of the sand, you and I and about five billion other people are going to go the way of the dinosaur. I'm talking planned invasion. The colonization of this planet by an extraterrestrial race.
Mulder: I thought you were serious.
Krycek: Kazakhstan, Skyland Mountain, the site in Pennsylvania. They're all alien lighthouses where the colonization will begin, but where now, a battle's being waged. A struggle for heaven and earth. Where there is one law: fight or die. And one rule: resist or serve.
Mulder: Serve who?
Krycek: No, not who. What.
