Aragoneu Aragoneu is a region of northwestern Mindartia in " Final Fantasy XI " . Its dry landscape hosts the capital of the Yagudo people and lies adjacent to the Grand Duchy of Jeuno . It connects to Derfland , a region of the western Quon continent , by means of the Great Jeuno Bridge . Aragoneu also borders Li ' Telor , a mysterious forested territory to the northeast . Conquest . This region is subject to conquest . Zones . Meriphataud Mountains . The Meriphataud Mountains are a vast array of rocky hills and crevasses lying north of Tahrongi Canyon . A gigantic bone - like structure , Drogaroga ' s Spine , divides them in half . Though Meriphataud is largely inhospitable , the Yagudo have established their stronghold , Castle Oztroja , in the eastern mountains and subsisted there for decades . Hidden in the northeast is the entrance to the Sanctuary of Zi ' Tah , a lush woodland entirely unlike its dusty neighbor . The winding road through Meriphataud is vital for wayfarers between the Federation of Windurst and Jeuno . Inexperienced adventurers that stray from the path may fall prey to Yagudo and Goblin patrols or the irritable Coeurls and Cockatrices native to Aragoneu . The region ' s outpost is located in this zone , in the northwest . During the Crystal War the mountains offered multiple routes to Fort Karugo - Narugo in the west . Much to the frustration of Windurst ' s veterans , this bulwark has fallen into disrepair and is not accessible in the present day . A Cavernous Maw connects Meriphataud to itself twenty years in the past , however , and therefore provides an opportunity for time - traveling tourists to behold the fortification in its prime . Sauromugue Champaign . Sauromugue Champaign is a desolate peninsula reaching into the ocean north of the Meriphataud Mountains . Its bridges cross the Bastore Sea to the west and connect the windswept plains to Jeuno and the Rolanberry Fields . These connections have made Sauromugue a prime historical battleground and it is littered with dilapidated fortifications . A Cavernous Maw links the champaign to itself twenty years in the past . Garlaige Citadel . Garlaige Citadel is an underground fortress in southern Sauromugue reconstructed during the Crystal War by the Royal Knights of San d ' Oria . Their intention was to surprise the Beastmen with attacks launched from the citadel . Though they were successful in this regard , their enemies eventually discovered a secret entrance and ambushed the Garlaige forces from inside . The subsequent slaughter demoralized the Alliance and facilitated the building ' s decline . In the present day the abandoned citadel crawls with vermin and undead horrors . Garlaige is notable for its use of " Banishing Gates " to seal off portions of its halls . These can only be operated by four people simultaneously standing on associated pressure plates . Having survived whatever dangers linger around the switches , the party members must then race through the unlocked portal before it seals again and separates them from their companions . Clever time - travelers can avoid this process by entering the citadel from another direction , however . Castle Oztroja . Castle Oztroja is a sprawling structure carved from the eastern Meriphataud Mountains by the Yagudo . It is equipped with sophisticated security features such as password - protected gates that frustrate uninvited guests . Members of the Theomilitary patrol Oztroja ' s halls at all hours in defense of their leader , Tzee Xicu the Manifest . Altar Room . The Altar Room lies deep within Castle Oztroja . It houses the most sacred relics of the Yagudo Theocracy , though few have ventured inside to determine what these might be . Rumors that magicite is kept here are of great interest to the Alliance of Altana . Attohwa Chasm . Attohwa Chasm is a parched , broken land in eastern Aragoneu . It is accessible only through the subterranean Maze of Shakhrami . Attohwa means " arid " in ancient Mithra n and its cracked earth distinguishes itself in a region of dusty wastelands by means of the toxic gas it expels . The chasm is not lifeless , however , as creatures ranging from foraging Antlions to poison - spewing Gasponia Flowers can be found in its fold . The eastern side of the chasm features a magnificent hill called Parradamo Tor . The route to its summit is very narrow and requires climbers to leap to lower ledges without falling off completely . Navigating its face can therefore be a considerable undertaking for unseasoned adventurers . A Cavernous Maw in the Buburimu Peninsula leads to another Attohwa Chasm in the alternate reality of Abyssea . Boneyard Gully . Boneyard Gully is a barren ravine resting atop the mountains of Aragoneu . Though nearby Attohwa Chasm features geysers of foul gasses , these emissions are concentrated in the gully . The resulting dark miasma denies access to anyone without an appropriate breathing filter . Once properly equipped , however , adventurers can challenge the Notorious Monster s that lurk in the boneyard . Some Mithran Sin Hunters use the gully to spar with whomever can be lured to it . They demonstrate little concern regarding the noxious fumes for which the area is famous .
