After the Mountain of Woe fell, Schala arrives with Janus to Terra Cave to find Melchior and Crono's party. She tells them that she has turned her back on Zeal. But then Dalton arrives and kidnaps her to take her back to Zeal.
Later, Crono's party confronts Dalton at Zeal Palace. After the battle and Dalton is defeated, he opens a portal and travels to the Ocean Palace deep under the water. So Crono's party follows him through the portal.
They are held captive aboard Dalton's Blackbird high up in the air. Fighting their way through the massive plane, they see flying next to them, Dalton in the Epoch. Dalton had attached wings to it and claimed it for himself. The party inevitably defeats Dalton, destroys the Blackbird and takes back Epoch.
