After defeating Dalton and recovering Epoch in 12,000 B.C., the party lands on Terra Continent and heads to the North Cape where a stranger was said to have been looking for them. The stranger turns out to be Magus.
Magus then agrees to join the party in an attempt to finally defeat Lavos once and for all. As they board the Epoch together, the Black Omen suddenly appears in the sky.
The party travels to The End of Time to ask the old man for advice, and he gives them the "Chrono Trigger", a magical egg with the power to bring the dead back to life. He says to find Belthasar because he knows how to use it.
Now in search of a Crono Clone, the team travels to the Millennial Fair to meet with Bekkler. He magically creates a doll clone and makes in appear at Crono's house. So the party goes to his house, picks up the clone and heads back to 2300 A.D.
Belthasar tells them the only way to bring Crono back is by taking those items to the top of Death Peak. Heading for Death Peak, they battle their way to the top where the magic transports them to the exact moment Crono was killed. They were in a "time freeze". They then exchange Crono out for the clone and are transported back to the summit of Death Peak with Crono, who suddenly stirs to life. They then return to the End of Time victorious and with Crono again part of the team.
