Atelier Ayesha - The Two Cradles

This is a set of events with Odelia where Keith and Ayesha find out about the Two Cradles. These events are necessary in order to finish Keith's ending. These can only be triggered before saving Nio, and not after. Defeat the Mecha Dragon and find information about the two cradles in the lab of Steinfeder. Afterwards, go to the Zweiteturm and speak to Odelia. She will give you more information about the two cradles.
