The Great Cavern of Wonders is a location in Crisis Core -Final Fantasy VII-. It is a long, deep series of caves that hide the game's superboss, Minerva. It is only visible in Missions, and the mission series 9-1-1 to 9-6-6 covers Zack's exploration of the cavern. Geographically, it is in the Icicle Area on the Northern Continent next to the Northern Cave. While its exact location is not known, its placement next to the Northern Cave suggests it is either within the North Crater or very near to it.
