Tu ' Lia Tu ' Lia , also referred to as the Gate of the Gods , is an island that floats miles above Vana ' diel in " Final Fantasy XI " . It was established by the Zilart ten thousand years before the beginning of the game ' s story and precipitated the fall of their civilization . Though history recorded that it had been destroyed when the Zilartian capital city sank into the sea , it escaped destruction and slumbered unopposed for millennia . It is the ultimate destination of the " " expansion . Owing to its location , Tu ' Lia is colloquially called " Sky " by the player community . Conquest . While this region is subject to conquest , it generates no produce and therefore has no associated vendor . Control of Tu ' Lia only determines which flag stands near the teleportal from the Hall of the Gods . Zones . Ru ' Aun Gardens . Ru ' Aun Gardens is a pentagonal array of floating islands that forms the exterior of Tu ' Lia . It is accessed primarily from a teleporter in the Hall of the Gods , the dilapidated temple of Altana that hides in the forests of northern Mindartia . A mechanism also exists to transport registered warriors between Ru ' Aun and the Halls of Transference within the crags at Konschtat Highlands , La Theine Plateau , and Tahrongi Canyon . Though abandoned for ten thousand years , the Gardens remain well - kept as a result of the many arcane groundskeepers and sprinklers that tend its landscape . In addition to a population of rare flamingos , Ru ' Aun boasts elementals of every variety regardless of the current weather . Four smaller islands orbiting the Gardens are inhabited by the Shijin , notorious beasts that serve as the divine guardians of the cardinal directions and their associated seasons . They are Byakko , who guards the West and the Autumn ; Genbu , who guards the North and the Winter ; Seiryu , who guards the East and the Spring ; and Suzaku , who guards the South and the Summer . Each is summoned by an offering of appropriate items collected from other residents of Tu ' Lia . La ' Loff Amphitheater . The La ' Loff Amphitheater is found within five satellite islands surrounding the Ru ' Aun Gardens . Each of its howling chambers has become the residence of one of the Crystal Warriors , whose powers seal the path to Tu ' Lia ' s core . The magical properties of the amphitheater may be modified by Ark Pentaspheres , enchanted parchments crafted under a full moon in Ro ' Maeve , to draw all five of these destructive entities to a single chamber . Ve ' Lugannon Palace . Ve ' Lugannon Palace is a ring of cermet halls that lies within the outer Ru ' Aun Gardens . It is partitioned by blue and yellow gates which are operated by corresponding color - coded switches . Opening yellow gates closes all blue gates and vice versa . This sometimes results in conflict when individual explorers are moving in different directions and carelessly blocking each others ' paths . Whatever prestigious guests it might have hosted in the past , Ve ' Lugannon has become little more than a breeding ground for golems and evil weapons . The arcane devices tending to the palace include watchful spheroid s among the more common cleaners . The Shrine of Ru ' Avitau . The Shrine of Ru ' Avitau is the heart of Tu ' Lia and lies at the center of Ru ' Aun Gardens . Like Ve ' Lugannon Palace , the halls of Ru ' Avitau are divided by blue and yellow gates which are operated by matching switches and cannot be opened simultaneously . Passage through the shrine is further complicated by teleporters which sometimes have multiple destinations . These result in groups being unintentionally divided as they navigate the area . Like Ru ' Aun , Ru ' Avitau is inhabited by all forms of elementals regardless of the weather . The arcane keepers seen in the gardens and palace also patrol its corridors . More importantly , the shrine is home to Kirin , master of the Shijin . Access to this famed manticore requires the defeat of his subordinates in Ru ' Aun as well as the use of a finicky teleporter that only travels to his chamber on even - numbered minutes . Celestial Nexus . The Celestial Nexus is a control center contained deep within the Shrine of Ru ' Avitau . It houses a massive crystal that functions as Tu ' Lia ' s core . The Nexus is the key to the ambitions of the ancient Zilart and therefore a decisive location for Vana ' diel as a whole . Other appearances . " Theatrhythm Final Fantasy " . The La ' loff Amphitheater appears as the BMS for " Fighters of the Crystal " . " Theatrhythm Final Fantasy Curtain Call " . The Amphitheater returns as the BMS for " Fighters of the Crystal " .
