Gustaberg Gustaberg is a region of southern Quon in " Final Fantasy XI " . The Republic of Bastok lies in the center of this rocky , arid region . While devoid of most forms of plant life , the area is abundant with various types of ore . It is this surplus of ore that has transformed Bastok into a mighty republic . During the Crystal War this region was incorporated into the Gustaberg Front . Because this region is directly adjacent to one of the starting nations , most of its content is geared to low - level jobs and new player characters . For this same reason , it is often the site of holiday events to ensure easy access to players of all level ranges . Conquest . This area is subject to Conquest . Due to its proximity , it ' s extremely rare for the Republic of Bastok to lose control of this region . Zones . North Gustaberg . Situated to the north of Bastok , this valley is surrounded by steep mountains . Separated into east and west areas by towering cliffs , this rocky region remains desolate due to various mineral run - offs which contaminate the river water . However , the spectacular " Drachenfall " , located to the north , is considered to be one of the wonders of Vana ' diel . The region ' s outpost is located in this zone . There are two Cavernous Maws in this area . A frozen maw just outside the exit of Port Bastok connects to the time of the Crystal War twenty years in the past . The active maw along the northern cliffs leads to the blighted Grauberg of the alternate reality of Abyssea . This zone also contains one of the entrances to Movalpolos . South Gustaberg . Spreading out to the south of Bastok is the rocky terrain of South Gustaberg . Plentiful with ore , hundreds of tunnels and mine shafts have been dug beneath the earth by Humes and Quadav alike . To the east , the Morhen Lighthouse can be found on the cliffs lining the Bastore Sea , its light guiding the way for the ferries and airships that traverse the area . A Cavernous Maw connects South Gustaberg to the Altepa Desert in the alternate reality of Abyssea . Zeruhn Mines . These mines were recently dug out of the large rock formation that lies in the Mines District of Bastok when a vein of Darksteel Ore was discovered within . Zeruhn has since become a reliable source of iron and a small supplier of zinc , silver , and darksteel , and because of its location within the walls of Bastok , Zeruhn Mines is safer for miners than the nearby Palborough Mines , which was recently retaken by the Quadav . This dungeon is quite small and suitable for very low level adventurers . The mines connect to the Korroloka Tunnel leading to Zepwell Island . Dangruf Wadi . Dangruf Wadi is a small gorge located near Mount Dangruf , an active volcano . Due to the extreme heat caused by the magma under the surface , numerous natural geysers can be found in this area . Some of these geysers are useful for transportation , operating like lifts for players . It is said that long ago , the Galka often would come to bathe in the hot springs here to relieve the aches and pains caused by the long hours they worked in the mines . Dangruf Wadi is considered a dungeon , in spite of being outdoors . This means that players cannot enter on a chocobo . When casting Escape , players will be removed to South Gustaberg . A northern exit in this zone leads to the base of the Drachenfall in North Gustaberg . Palborough Mines . Palborough Mines was once a Quadav settlement , nestled beneath the earth just outside North Gustaberg . That was until a vein of mithril was discovered . It was captured , forcibly , by the Republic of Bastok which then used these mines to gather most of the metals that they have today . They would still be mining there today , but the Quadav have since taken over the mines and use them for their own resources . Waughroon Shrine . The Waughroon Shrine is a place of worship for the Quadav built deep within the heart of the Palborough Mines . There are no enemy creatures in the zone , normally . This is one of the many Burning Circle s where players can choose to take on special fights against predetermined enemies for potentially great rewards . Korroloka Tunnel . Korroloka Tunnel is a cave system located deep beneath the sea floor . It was originally used by the Galka to flee from their native lands to the Quon Continent when they were driven out by the Antica . The interior of the cave is formed from a terrestrial coral . In spite of its beauty , though , the Galka think of it as a place of tragedy and death , where the coral thrived on the blood of fallen comrades . Korroloka still functions as a land - bridge beneath the sea between Bastok and the Kuzotz region . All players wishing to use Teleport - Altep will have to travel through this cave system at least once to get to the Altepa Crystal . Since it is underground , it cannot be accessed by players riding a chocobo ; they must walk the way through while avoiding the creatures living in this tunnel . The spell Escape will take players to the Zeruhn Mines . This zone requires " " expansion to access . Other appearances . " Theatrhythm Final Fantasy " . Gustaberg appears as the FMS for its eponymous theme . " Theatrhythm Final Fantasy Curtain Call " . Gustaberg returns as the FMS for its eponymous theme .
