Living in the seemingly peaceful kingdom of Guardia in 1000 A.D., the child CRONO was chosen by guardian spirits to save the world from ultimate devastation. Though Doomsday will not happen until the year 1999, the ancient seeds of destruction were planted long ago by the evil LAVOS. Your mission in the world of CHRONO TRIGGER is to travel back and forth through time to change the course of history, and stop Lavos from succeeding in his dark plan. On your journey, you will battle monsters and meet many helpful people in both the past and the future. Some will become your faithful and powerful companions, while others will give you clues by telling you stories. Pay attention to what they say, and good luck in your adventure.

There is a total of 26 stages in Chrono Trigger. Stage titles are declared to you through the save interface along with your party members. There is also 14+ endings, some of which have multiple variations.

This walkthrough begins with stage one, The Millennial Fair, and progresses through to stage twenty-six, The Final Battle. Depending on which version / platform you are playing on, objective titles and item titles may vary. DS introduced extra content such as Lost Sanctum and Dimensional Vortex (Arena of the Ages isn't covered by my walkthrough).
