Miranda O'Brien: This settlement was founded by the crew of a Starfleet vessel that crashed on this planet two centuries ago. I realize this is going to be hard for you to accept but that ship was the Defiant
. Two days from now, when you leave here and try to pass through the energy barrier, you'll be thrown back in time two hundred years. You'll be stranded here and become the founders of this settlement. We are your descendents.
