From the PDF: They have journeyed back at the cost of great pain and personal sacrifice from a world after the war that ended everything. They seek knowledge of this past. They must know the cause, for to know the cause is to alter their own dismal present. Somewhere here, there are answers. They know this, for they have already discovered some clues, scraps drawn from the mouths of prisoners as they died from the drug. The Bear. Every prisoner spoke of it ­­ the last words from their dry, blackened lips. Someone here will lead them to it. If they can know The Bear, they will own the future.
