Temple of the Ancients

After the events of FFVII, the Temple of the Ancients was thought to be lost, however it had recently revealed itself for reasons unknown even to the wisest of beings. Within the Temple it is basically the same as it ever was, only now the air reaks of death and sadness, much more sadness than before. Perhaps the Ancients need something else to be done about the world? Entrance to the Temple is strictly prohibited to all who do not carry the item "Keystone". There is but one Keystone in the world, and the keeper of this said Keystone is none other than Cloud Strife, so if you think you can take it from him, be my guest.
