Now on a mission to find the ancient red mineral to repair the Masamune sword in order to fight Magus, Crono and his party leave Medina in 1000 A.D., pass through the pillars of light at The End of Time, and travel to 65,000,000 B.C.
Upon their arrival through the Time Gate at the Mystic Mountains in the Prehistoric Era, Crono's party is confronted by humanoid reptilian creatures called Reptites. Finding themselves overwhelmed, a native of the era, a prehistoric human named Ayla, comes to their aid.
Ayla agrees to give them the red rock they seek, but first invites them to a celebration to welcome the newcomers to her village. During the party, Crono and his friends get acquainted with the prehistoric people and the era, and Ayla gives Crono the red rock. The celebration continues well into the night.
