 After meeting and repairing Robo, Crono and his friends find Gaspar, an old sage at the End of Time, who helps them acquire magical powers and travel through time by way of several pillars of light (from this point onwards, the party is able to challenge Lavos; doing so and emerging victorious will unlock one of twelve different endings, depending on the point in the story at which Lavos is fought, as well as whether or not certain actions are completed beforehand).Research in AD 1000 tells the party about Magus summoning Lavos into the world in 600 AD, but Frog needs to reforge the legendary sword, Masamune, to open the way to Magus's castle.To get the ore to reforge it, they travel to prehistoric times and meet Ayla.
