Gustaberg Front The Gustaberg Front is a theater of the Crystal War in " " . It includes the southernmost territories of Quon , where the Republic of Bastok risks being overrun by the Quadav Shieldwarriors . The front contains the city of Bastok in addition to portions of the post - war Gustaberg and Zulkheim regions . Zones . Bastok Markets . Bastok Markets is the heart of the Republic ' s war effort . With the port lost to Sahagin and the mining district pressured by its proximity to Antica and Quadav - infested tunnels , the markets are the nation ' s last line of defense . They have been heavily reinforced for this purpose and form a barrier around the metalworks , where the government resides . North Gustaberg . North Gustaberg is a large valley found northwest of Bastok and south of Grauberg . A mountainous cliff divides Gustaberg in half and a ramp carved into its face is the only means of passing from one side to the other . Water cascading over this boundary , though undrinkable due to mineral contamination , forms a dramatic natural wonder , the Drachenfall , which feeds Zeikt Creek as it flows west into Dangruf Wadi . Unfortunately for patrons of its hot springs , Dangruf is among many neighboring areas , including South Gustaberg , the Palborough Mines , and Movalpolos , that are inaccessible during the war . Encroaching Quadavs and Goblins make travel through Gustaberg dangerous even in absence of enemy troop movements . A Cavernous Maw connects the valley to itself twenty years in the future , however , providing an escape to less threatening times . Invincible Shield , a famed Galka warrior , leads the Republican Army ' s 3rd Division in Gustaberg ' s defense . In turn , the Quadav Shieldwarriors assigned Do ' Bho Venomtail and the Dadough Vanguard to seize control of this area . Do ' Bho ' s mastery over poison magic is unparalleled . Grauberg . Grauberg is a network of hills and vales lying south of the Pashhow Marshlands . It became a vital supply route for the Alliance of Altana after the western roads through the Konschtat Highlands were lost as a result of the Battle of La Theine . It is home to exotic creatures such as Pixies and Wyverns . A fair Elvaan maiden named Areuhat is known to wander the area with no apparent fear of its dangerous inhabitants . Bastok ' s military efforts in Grauberg are headed by the 2nd Legion Scouts under the command of Adelheid Sturm , a Hume scholar . She notably invented a range of status - inducing Tube s that detonate in the presence of enemy infantry and deploys these on the battlefield to confound the Beastmen . In turn , the Quadav Shieldwarriors assigned No ' Mho Crimsonarmor and his elite guard to seize control of this area . No ' Mho bombards the opposition with divine magic . An alternative version of this region exists in Abyssea . It is accessed via the Cavernous Maw located in North Gustaberg . Ruhotz Silvermines . The Ruhotz Silvermines are an vast array of excavated tunnels stretching between Gustaberg and Rolanberry Fields far to the north . They were once a profitable enterprise for the Republic but were adopted as a supply route by the Quadav . Bastok has consequently attempted to secure the mines and they remain a volatile channel for subterfuge from either side .
