While exploring the spacecraft under Payton's radio guidance, Bower talks with Payton about Pandorum, a psychological condition brought on by extended periods of deep-space travel and hypersleep. Its symptoms and effects include severe paranoia, vivid hallucinations, and homicidal tendencies. Payton recounts the story of another ship, the Eden, in which a single member of the flight crew, affected by Pandorum, jettisoned 5000 others into the oblivion of space. As Bower continues searching the ship, he encounters dead bodies and fast-moving humanoid creatures. //wikipedia
