Zodiac Stones
From Final Fantasy Wiki
The Zodiac Stones are relics in Final Fantasy Tactics. There are a total of thirteen Zodiac Stones. Twelve are associated with signs of the Zodiac, while the thirteenth is associated with Serpentarius, (an alternate fictional name for the Ophiuchus constellation) created by the mysterious Elidibus.
[edit] Origin
The Zodiac Stones are twelve Auracite crystals that are branded with the twelve signs of the Zodiac. It is a prominent elements in the story of the Zodiac Braves, a legend highly regarded by the Church of Glabados as the central doctrine of the religions' teachings. The twelve Zodiac Braves, in legend, had fought against the Lucavi, driving them back into the spirit world. The legend goes on to say that the Braves, carrying the Zodiac Stones in hand, would come to save humanity should they be in peril.
[edit] Truth
In reality, these Zodiac Stones are connected to the Lucavi demons, providing conduits for the demons to exist in Ivalice. It's never clear whether or not the stones were made by the Lucavi or simply used by the Lucavi, but at least one incident seems to show them as not having their own alignment; such as in the case of Marach Galthena, who was revived by a Zodiac Stone due to his sister Rapha's wish. At least seven Zodiac Stones are associated with Lucavi. The Scorpio Stone is tied to Cúchulainn, the Aries Stone is tied to Belias, the Gemini Stone is tied to Zalera, the Capricorn Stone is tied to Adrammelech, the Leo Stone is tied to Hashmal, the Virgo Stone is tied to Ultima herself, and the Serpentarius stone is connected to Elidibus' Lucavi form.
Ramza collects these stones as the game progresses and he kills the Lucavi associated with them. Although Ramza effectively collects all thirteen (assuming the player completes all sidequests), the Leo and Virgo stones cannot be viewed as items from the menu, since they are not recovered until the final sequence of battles.
