Merged World The Merged World ( also known as the Original World or Third World ) is the title given to the third of three worlds in " Final Fantasy V " . It is , as its name suggests , a merge of both Bartz ' s World and Galuf ' s World . The Merged World ' s geography is that of Bartz ' s World and Galuf ' s World fitted together . Locations that were not accessible previously due to the means of access being on the other world are now open for exploration . The landscape is now one large continent . Story . The Merged World is how the world originally was before its crystals were separated 1 , 000 years ago , thus splitting the world into two . This was done to seal the power of the Void in the Interdimensional Rift between the worlds , so none could harness its might for evil . The warlock Exdeath succeeded in claiming the crystals and shattering them , thus pulling the two worlds back into one , and in doing so , gaining access to the power of the Void . Before their demise the crystals had branded Bartz , Lenna , Faris and Galuf the Warriors of Light tasked with vanquishing Exdeath and protecting the crystals . Though they failed to stop Exdeath from shattering the crystals , and Galuf was killed and his mantle taken by his granddaughter Krile , the Light Warriors continue on their quest to destroy Exdeath once and for all . The party infiltrates Castle Exdeath in Galuf ' s World and encounter Gilgamesh , but his poor choice of weapon is no threat and Exdeath banishes him to the Interdimensional Rift for his failure . Exdeath battles the party at the top of the castle and though he appears defeated , he shatters the remaining crystals . The Light Warriors black out and awake near Castle Tycoon , which throws a celebration for the return of the princesses Lenna and Sarisa ( Faris ) . Bartz and Krile slip out to discover why they returned to the first world , and are soon joined by Faris , who grew tired of being royal . They learn from the great sage Ghido the two worlds have been merged into one . Long ago , the world was split into two to seal the power of the Void , a destructive power of unknown origin , lest it be used for evil . Now that the world has been restored to its original state the power of the Void has been released to be used by Exdeath . The Light Warriors must obtain the Sealed Weapons , a set of twelve legendary weapons from a thousand years ago , to survive the Interdimensional Rift , an otherworldy dimension existing in the rift between worlds , and destroy Exdeath . Exdeath emerges from a splinter in Krile ' s hand and knocks them out , although Ghido fights him to a standstill . Exdeath uses the Void to destroy several locations by casting them into nothingness leaving but black holes behind , including Castle Tycoon and Lenna with it . After obtaining the first seal from the Pyramid of Moore to unlock the legendary weapons , the party reunites with Lenna , who was saved from the Void by Hiryu , her wind drake . Hiryu sacrifices himself to help drive the demon Melusine from Lenna ' s body so the other Light Warriors can defeat her . Exdeath strikes again with the Void , seemingly to taunt the party as well as removing Ghido . Among the towns he attacks is Lix , Bartz ' s hometown . An enraged Bartz almost destroys their airship by pushing it to unreasonable speeds before the others calm him down . They reunite with the scholars Cid and Mid after traversing Fork Tower to obtain the Flare and Holy spells , and the pair gives the airship an undersea function . The Light Warriors travel all over the Merged World to unlock the legendary weapons using the seals from the Island Shrine , Great Sea Trench , and Istory Falls , defeating the demons Exdeath sent to stop them . They find Faris ' s sea dragon Syldra as a summon spirit in the Pirates ' Hideout and Hiryu as the summon Phoenix at the top of Phoenix Tower . Now fully prepared , the Light Warriors fly the airship into the Interdimensional Rift that has opened over Tycoon . They fight through the hodgepodge of environments seemingly put together from the places the Void consumed until they reach the final floors , a world of crystalline darkness . Exdeath reveals his true form : the Moore tree . The Great Forest of Moore in Galuf ' s World had once been used to seal evil spirits , until the day the spirits sealed in a tree became a sentient , malicious being . He tries to destroy the Light Warriors with the Void , but the spirits of the Dawn Warriors — Galuf , Xezat , Dorgann , Kelger — as well as King Tycoon , save them , allowing the party to confront Exdeath in battle . Halfway through the fight he is consumed by the Void and becomes Neo Exdeath , an entity — the manifestation of the evil spirits trapped within the Moore tree that was Exdeath — that seeks to turn all of creation to nothingness . At great length , they defeat it . For a short time , the Void lingers . The essences of the elements carried by the party — Hope , Courage , Devotion , and Passion — imbue the crystal shards they carry , and the crystals are reborn in the places that held the weapon seals . It is told the Void existed before the world , and that the crystals that sustain the planet were born in the Void and thus created the world . From this it can be drawn that the Void is the original state of the universe from which all life was formed . King Tycoon and the Dawn Warriors thank the party for saving the world and Krile ' s wind drake appears to take them back . A year later , Krile writes to Mid and tells of what the Light Warriors have been up to . Bartz has resumed wandering . Lenna and Faris returned to Tycoon , although Faris cast aside the life of royalty to rejoin her pirate crew . Krile herself returned to Bal . She visits the Guardian Tree on the anniversary of Galuf ' s death , feeling sad and lonely , but the others join her and remind her she isn ' t alone . Should any of the party have fallen in the final battle , they are revived at the Guardian Tree . Together , they vow to continue protecting the crystals . Musical themes .
