Abyssea Abyssea is a dimension existing parallel with Vana ' diel in " Final Fantasy XI " . A land fraught with perils , Abyssea is home to savage hordes of heretofore unseen creatures . Although Abyssea was originally identical to Vana ' diel , certain events have caused the land to crumble away . Adventurers from Vana ' diel gain access to Abyssea through numerous Cavernous Maw s scattered across Vana ' diel with the use of Traverser Stones . Areas within Abyssea serve as the setting for all three Abyssea battle add - ons , " " , " " , and " " . Areas . Abyssea - La Theine . Once an idyllic plateau , this area has been twisted into a hellish nightmare of its former self by the unrelenting Abyssean hordes . What San d ' Orian survivors there are now hide in the various alcoves scattered throughout the plateau . Abyssea - Konschtat . These highlands , once a lush landscape diverse in life , with soft winds gracing the grass , now lay under a dark sky , the wind now cold and stale with the stench of dried blood . Scattered across these highlands are small encampments of the survivors of the Abyssean hordes , pushed from their homes by the fell creatures . Abyssea - Tahrongi . Once a land of peace and tranquility in a world similar to Vana ' diel , is now little more than the Alamo , the last stand , for the few survivors of this forgotten world . Fell creatures now swarm through the dry desert of oblivion with an insatiable desire for violence . Abyssea - Attohwa . Another one of the many Abyssean fronts , this inhospitable chasm is now home to a handful of survivors - forced to crash - land here after their airship fell to the Abyssean swarm . The thick , noxious miasma , potentially poisonous flowers , and arid climate are but a few of the many challenges these last survivors face . Abyssea - Misareaux . At one time , this area was a peaceful , if isolated , meadow . Those days have long since passed with the arrival of the Abyssean plague that currently infests the land . Now , marooned survivors from a recent shipwreck find themselves in a constant battle for their very lives . Abyssea - Vunkerl . Like Vana ' diel , Abyssea had the Crystal War . Like Vana ' diel , this river delta was a major strategic area during that conflict . Unlike Vana ' diel , however , it has most certainly not been forgotten to the mists of Time , as a handful of San d ' Orian and Jeunoan refugees stage another battle in this shattered land ; not for control , but for survival . Abyssea - Altepa . Windswept ergs and stalwart potreros dot the landscape of this desert of ruin . When the cataclysm began to ravage the world , a series of earthquakes collapsed the Quicksand Caves along with other important escape routes . The desert ' s tranquil silence was shattered by the cacophony of war - a symphony of death that continues to this very day . Abyssea - Uleguerand . Howling katabatic winds race down unforgiving mountains caked with ice and snow , forcing Abyssean stragglers to cluster around small campfires . As the war rages on and casualties mount , it becomes ever more difficult to distinguish blood - soaked snow from snow stained by the everlasting vermilion sky . Abyssea - Grauberg . Craggy mountains and verdant meadows carve the landscape of this topographically diverse region . Like its neighbor , this area is host to monsters that constantly push the defense lines of the battle - hardened Abysseans . Unlike its neighbor , however , this area is also host to far stronger monsters lurking in the shadows . Abyssea - Empyreal Paradox . Located high above the looming Abyssean moon , this version of Al ' Taieu ' s inter - dimensional juncture is the site of the final confrontation between those who would save Abyssea and those who would destroy it . Only adventurers in possession of a crimson traverser stone are able to enter this area .
