Auracite Auracite , also called Holy Stone and Zodiac Stone , is a form of magicite in the world of Ivalice . They are crystals , a recurring motif in the " Final Fantasy " series . They are magical in some way and sometimes aligned with the zodiac signs . Appearances . The Occuria created auracite from two large crystals called auralith s that contained tremendous amounts of magick , in much the same way they had created nethicite from the Sun - Cryst . The Occuria gave this auracite to Feolthanos , the leader of the aegyl , intending to use him as they had used King Raithwall . Feolthanos enraged the Occuria by refusing to serve them ; instead he and the aegyl fled to the sky continent of Lemurés where he used the auraliths to create a barrier around his floating world . Aegyl use pieces of auracite to summon Yarhi ( called Espers by those from other parts of Ivalice ) through a device called the Ring of Pacts . The auracite has an effect the aegyl are unaware of : creating a guardian Yarhi strips away part of the user ' s anima and transfers it to Feolthanos . Thus , through thousands of years using auracite to defend themselves against unbound Yarhi , the aegyl have been reduced to little more than soulless shells while Feolthanos has grown more powerful . Feolthanos has collected so much anima that he has crystallized and become an auralith himself . While the party speculates that the sky pirates who have begun using auracite may have started to lose their anima , none of the party members from outside Lemurés seem to be affected . " Final Fantasy XIV " . Auracite is mentioned by Unukalhai as being involved in the fate of another world . It was used by its realm ' s champions to contain the power of primal s , but due to a fatal flaw , it gradually bled out the energies and changed its wielders into fiends of endless appetite , devouring their world ' s life force . A similar object , the White Auracite , was a pale stone that could be used to trap an Ascian , allowing them to be destroyed by striking it with sufficient amounts of aether . The Warrior of Light used these to destroy both Nabriales and Igeyorhm . " Final Fantasy Tactics " . The thirteen auracites are crystals that hold the spirits of Lucavi , demons from another realm , some of which appear as Espers in " Final Fantasy XII " . Auracites are known as the twelve Holy Stones / Zodiac Stones of the Zodiac Braves of Ivalician legend . The auracites are artefacts . Twelve are associated with signs of the zodiac , while the thirteenth is associated with Serpentarius . The story of the Zodiac Braves is a legend highly regarded by the Church of Glabados as the central doctrine of its teachings . The twelve Zodiac Braves are said to have fought the Lucavi , driving them back into the spirit world . The legend foretells that the Braves , carrying the Zodiac Stones , would come to save humanity should they ever be in peril . In truth , the auracites facilitate the Lucavi ' s existence in the mortal realm via possession of those who hold their auracite . They may not be entirely evil , as one helps revive Marach after he is shot while defending his sister . Marach claims to have heard a calm , gentle voice telling him to go back . Ramza speculates the stones are raw power shaped by the will of its wielder . To release the Lucavi seal in the auracite , the stone needs a vessel . It is believed that the host must have the same zodiac sign of the auracite and requires that person to become the Lucavi ' s vessel , but this is not necessarily true ; e . g . Wiegraf Folles is a Virgo , but is possessed by Belias , an Aries . In the case of the Lucavi leader , Ultima , there can only be one vessel for her auracite in so many generations . " Final Fantasy Record Keeper " . The Aries stone is an accessory , and was attainable by defeating Belias in a " Final Fantasy Tactics " event .
