In 1000 A.D., Crono and Marle watch Lucca and her father demonstrates her new teleportation device at the Millennial Fair. When Marle volunteers to be teleported, her pendant interferes with the device and creates a time portal that she is drawn into. Crono and Lucca separately recreate the portal and find themselves in 600 A.D. They learn that Marle's presence has created a grandfather paradox by preventing the recovery of Marle's kidnapped ancestor.
