Now on a quest to rescue Queen Leene, Crono and Lucca head back through Guardia Forest and west to the Cathedral. While there, they find that monsters have been disguising themselves as humans. They also team up with a newcomer. He's a talking humanoid frog who aptly calls himself Frog. After battling some of those monsters, they finally find the real Queen Leene. As it turns out, Yakra has been masquerading as the Chancellor. Yakra was the one behind the Queen's kidnapping.
Crono, Lucca and Frog defeat Yakra and bring both the Queen and the real Chancellor back to Guardia Castle where they find Marle has suddenly reappeared. Knowing the Queen is finally safe, Frog decides to head back out on his own while Crono, Marle and Lucca go back through the Forest, Truce and up through Truce Canyon to the Time Gate. Lucca uses a device she created called the Gate Key to open up the portal manually. Together, the three of them jump back to 1000 A.D.
