World B World B is the world of " Dissidia Final Fantasy " and its prequel " Dissidia 012 Final Fantasy " , though it is only named and shown in the prequel . It is a near - mirror image of the world of the original " Final Fantasy " , which is called World A in " Dissidia 012 " . In " Dissidia Final Fantasy " , it was implied the world was formed from fragments of other " Final Fantasy " worlds that had been destroyed . " Dissidia 012 Final Fantasy " retconned this with World B , and the usage of gateway s to explain how the characters can appear in parts of other worlds . Story . Chaos , Cosmos , and Cid of the Lufaine came to World B from World A when Chaos opened a portal to the Interdimensional Rift that drew them into it . Shinryu was visiting World B , one of the many dimensions connected to the Rift , and took an interest in them . Cid made a pact with Shinryu to gain immortality in exchange for giving up his body , and Chaos and Cosmos would war with each other using World B as the battleground , and calling warriors from other worlds through the Rift to their side to fight for them . Cosmos made her throne in Order ' s Sanctuary on an island off the coast of Cornelia , while Chaos ' s throne lay inside a volcano on a floating island near Onrac . In the twelfth cycle of war , Exdeath opens a portal to The Void near Onrac and releases the manikin s the Onrac of World A had produced and sealed away . The manikins swarm the world , threatening to overwhelm Cosmos ' s forces with sheer numbers , until six warriors venture into the Land of Discord and sacrifice their lives to close the portal . In the thirteenth cycle the southern regions of the world are destroyed when Chaos kills Cosmos , but her warriors survive due to the light of their Crystals and make it to Chaos ' s throne and destroy him , ending the cycles of war and spiriting them home . In a secret ending , once Cid is freed from the nightmare world depicted in Confessions of the Creator , he tells Cosmos , who has revived in World B and was waiting for him , that the world will collapse into the Rift now that the balance of power between her and Chaos is shattered . Cid offers Cosmos to come with him on a journey , but Cosmos rejects the offer , choosing to stay and reign over the abandoned World B for as long as it has left . Locations . With the exception of Confessions of the Creator , the player is restricted on which areas of World B can be explored depending on which storyline they are playing . Certain gateways may be inactive in one story , but active in another . Confessions of the Creator gives the player free reign to explore as they wish , and features Teleport Stone s to warp the player around the world . Connection to World A . The regions of World B are named after World A ' s , and several gateways are directly named after locations in World A . Though they are similar , there are several geographical differences . There is a circular island in World B off the coast of where Cornelia is in World A - this island houses Order ' s Sanctuary . The island chain between the two northern continents in World A is a continuous strip of land in World B , and the northwest continent in World B , the Lands of Discord , have a chain of floating islands on their eastern shores housing the Edge of Discord gateway where the Edge of Madness , the seat of Chaos , lies . Peninsulas on the eastern edge of the map and near Melmond are lengthened to provide land bridges , and there are numerous additional small islands , including the Shinryu Isles in the southeast , that contain a Teleport Stone to the Land of Discord .
