Picard: Guinan, activate your viewscreen. I want you to monitor what's going on up here. I may need your input.
Guinan: I'm here. I can see the other ship.
Picard: You are acquainted with this life form?
Guinan: Yes. My people encountered them a century ago. Our cities were destroyed.... our people scattered across the galaxy. They are called the Borg. Protect yourself or they will destroy you.
