Occuria The Occuria are the most powerful beings in the world of Ivalice in " Final Fantasy XII " . They are referred to , by themselves and others , as " The Undying " , though their existence is unknown to Ivalice at large . The Sage Knowledge available via the bestiary suggests the Occuria used to live on Ivalice among the other races before withdrawing into their own realm . The Occuria live high above the Giruvegan , higher than any airship can reach . Despite apparently being responsible for much of the development of Ivalice , the Occuria only appear in " Final Fantasy XII " and are only briefly mentioned in " " , without so much as a mention in the rest of the " Ivalice Alliance " . The Occuria are willing to do whatever it takes to modify the course of Ivalice to their standards , including using phantom images of loved ones to manipulate people and sealing away insubordinate races who refused to accept the Occurian weave of fate . Profile . The Occuria are apparently genderless , though they possess masculine titles and voices that sound simultaneously male and female . They can create and appear as ghosts and images , and can render themselves invisible and inaudible to anyone other than people they want to see and hear them . Their natural form is a floating specter with an ornate , armor - like appearance . The Occuria have no visible faces , only glowing yellow eyes floating in an empty void , vaguely reminiscent of a Black Mage . An Occuria ' s physical manifestation exudes a great deal of Mist . They can possess other beings , and merge with them to drastically increase their strength and power . The Occuria are said to be immortal , but can die if they merge with or possesses mortals who are killed . Story . " Final Fantasy XII " . Occuria are concerned with controlling the course of Ivalice ' s history and created the Espers as their servants . The Espers came to believe themselves as powerful as their creators and tried to destroy them . The revolt was led by the Esper Ultima , with the only Esper not included being Zodiark . The Occuria threw them down and bound them with glyphs . The Occuria tried to influence the garif and granted them deifacted nethicite . The garif could not wield or control the magickal stones and would only worship the Occuria . The Occuria tried again , successfully this time , to influence the world of Ivalice by offering the nethicite to a man who would destroy or subjugate other nations as they directed . This man was King Raithwall , who would become the Dynast King . At some point in the intervening time , one of the Occuria went rogue , disagreeing with the Occurian philosophy . Venat felt all races should have control over their own history and concocted a plan to create nethicite that was not under the control of the other Occuria , manufacted nethicite . Venat accomplished this with the aid of Dr . Cid of Archadia , with the Emperor ' s son Vayne Carudas Solidor aiding them by setting up the Empire ' s war against Rozarria and taking the shards cut by Raithwall from the locations they conquered . Enraged at Venat ' s heresy , Gerun and the other Occuria decide to bring forth a new Dynast King to destroy Archadia and restore the status quo they had created . The Occuria ' s choice is Ashe , whom they manipulate by creating an image of her late husband Lord Rasler , which she mistakes for his spirit . She meets them in person in Giruvegan and the Occuria reveal their intent of controlling Ivalice ' s history , though they explain it to her by claiming that if history is not in their control it would lead to disaster . To ensure she does what they intend , the Occuria give Ashe the Treaty - Blade to cut a new shard of nethicite from the Sun - Cryst , tempting her to use its power to take revenge on Archadia and restore her kingdom of Dalmasca . When she reaches it , however , she realizes Rasler would not want her taking revenge , and realizes what she thought was his spirit was just an illusion created by the Occuria . Though the Occuria try and convince her to take the nethicite , Ashe informs she will not be their pawn and destroys the illusion . The rogue Occuria Venat meets its end as the Resistance engages the Archadian Imperial Fleets in the battle above Rabanastre . Venat fuses its powers with Vayne Solidor , transforming him into The Undying , but Ashe and her friends defeat Vayne even with his enhanced powers . Vayne apologizes to Venat for not being a true Dynast - King , but Venat tells Vayne their goals have been fulfilled and that they will walk the path of death together . " " . When Balthier explains the origins of Lemurés a picture of the Occuria appears . When the Occuria tried to control the aegyl like the other races , the aegyl fled to the floating continents . Angered , the Occuria used the Auralith s to create a barrier around Lemurés to trap those who would not follow them . Over the years , the aegyls ' resentment towards the ones who chased them out their homelands grew . Imprisoned above the clouds , the aegyl leader , Feolthanos , became consumed by his vindictiveness . Associating the Occuria ' s meddling with the wills of the entire Ivalician land , Feolthanos plots a crusade against the " underworld " from his Keep of Forgotten Time . The destruction of the Sun - Cryst and repudiation of the Occurian mandate dissolved the barrier around Lemurés and allowed Feolthanos to send the Judge of Wings to wreak havoc on the world from which the Undying exiled his people . Development . The Occuria were first designed to be a race of mindflayer s , as revealed in the " Final Fantasy XII Ultimania Omega " . Earlier concept artwork reveals these " mindflayers " are draped in luxurious robes and turbans . They were depicted lounging in their bar and smoking pipes . Revisions were made and the Mindflayer was placed as a Mark , retaining the initial design . Occurian speech resembles an archaic , poetic form of absent of particular rhotic vowels in both speech and writing . The rogue Occuria , Venat , speaks in , while the other Occuria speak in , both commonly used types of metrical line in traditional English poetry and verse drama . The decision to use metered verse with an unusual rhyme scheme came about as a solution to the problem presented by the voice processing used for the Occuria in the Japanese . The multiple layers of voice had an otherworldly sound , but made it difficult to discern what was being said though helped by the on - by - default subtitles . The localized version has subtitles off by default , so the translators needed something else to differentiate their speech . The actress used for the Occurian leader Gerun , Bernice Stegers , is a British stage actress who knew what to do with the lines . Musical themes . The music that plays when the player meets the Occuria in the Great Crystal is called " Abandoning Power " . Etymology . The name Occuria may derive from the word " curia " , a word that comes from the Latin " coviria " , meaning " men community " . The word " curia " refers to the subdivisions of a tribe in ancient Rome , the Roman senate during the republic and any of several medieval councils or courts of justice , reflecting the Occuria ' s role as the leaders of Ivalice . The oc - prefix may derive from the English word " occult " meaning hidden or secret . The name Occuria may also derive simply from the English words " occurrence " or " occur " as the Occuria have displayed a sense of entitlement over the history of Ivalice and are known to have directly influenced its actuation until the events of " Final Fantasy XII " .
