The Cave of the Circle (魔方陣の洞窟, Mahoujin no Doukutsu?), also known as the Magic Circle Cave, is a location in Final Fantasy III accessed from the back room of Doga's Manor. Doga accompanies the party to the end of the cave in order to make the Nautilus submersible. The party must stay in Mini status throughout the cave.
In order to obtain the Eureka Key, Doga orders the Light Warriors to accompany him through the Cave of the Circle. At the bottom, he warps himself to another dimension, and the Warriors back to his manor, after casting a spell that allows the Nautilus to submerse itself. Then, he asks the Warriors to wake Unei from her sleep by obtaining Noah's Lute at the Temple of Time.
