Only the chosen may enter that land. The chosen will touch all creation, and obtain that which is truth. It is reason outside of reason—the reason of Agito. It is power—the authority of Agito. The sage proclaims: 'In all things, there is meaning. In all things, mourning will end. Make your choice: will you choose reason, or the power of kings?' And unto him, I reply: 'I will become Agito. I will sound the knell to shake all the world. When nine and nine meet nine, the depths of reason shall stir. When the seal of creation is broken, a voice like thunder shall sound, and thou shalt know—we have arrived.'
The player controls Zidane and Quina as they defeat the Earth Guardian and collect the Earth Mirror, while the other Guardians are defeated by other party members outside of the player's control. Unlike the Fire Guardian and Wind Guardian, Garnet and Eiko's victory over the Water Guardian is not shown in a cutscene.
When the party is traveling through Memoria, the game's final dungeon, the four Guardians reappear and morph into their true forms, just as they were in Final Fantasy; the Water Guardian is fought in the form of the Kraken. Thus, the Water Guardian art is something of a curiosity: it never appears in the game, but its artwork still exists, even though the Kraken has its own model and artwork.
