Enterprise ( Final Fantasy IV ) The Enterprise is an airship in " Final Fantasy IV " . It is the game ' s first airship and it cannot land in forest s , deserts , mountain s , or oceans . It is equipped with a remote control invented by Cid Pollendina , designer of the " Enterprise " . Story . Cid Pollendina , an engineer working for Baron , was commissioned to work on a new airship for the kingdom ' s air force , the Red Wings , and designed the " Enterprise " . He opposed its use for evil and refused to show it to the King of Baron and hid it before being imprisoned for treason . It is later discovered the king was , in fact , Cagnazzo , one of the Archfiends posing as the king . Cecil Harvey and his friends defeat Cagnazzo , and free Cid who shows Cecil the " Enterprise " and offers it to him to use in his fight against Golbez , a knight attempting to steal the world ' s Crystals . When the " Enterprise " launches , Golbez ' s underling Kain Highwind leads the Red Wings to issue an ultimatum to Cecil . Cecil must get the Crystal of Earth from Troia , or else his love Rosa would die . Cecil ventures to Troia and discovers the Crystal was stolen by the Dark Elf who lives in the Lodestone Cavern on an island not accessible with the " Enterprise " , so he must use a black chocobo to get there . After obtaining the Crystal , Kain directs Cecil ' s party aboard the " Enterprise " to the Tower of Zot , Golbez ' s headquarters where Rosa is being held prisoner . After rescuing Rosa , Cid uses the remote control feature to return the " Enterprise " to Baron town ( Rosa had to warp the party out of the collapsing tower ) . They take the " Enterprise " to Agart in search of the Underworld , whose Dark Crystals the party surmises Golbez will be after next . Cecil throws the Key of Magma into a well in the center of town , and a massive hole opens in the mountains to the north . The party flies the " Enterprise " into the hole , and finds the Underworld . The Red Wings battle the dwarves in the underworld and the " Enterprise " is damaged by stray fire . Cid must repair it and take it back to Baron to wrap it in mystic silver to make the airship withstand the intense heat of the Underworld . When he returns he is just in time to save Cecil and his friends from falling into the lava . The Red Wings have also been modified , and have the " Enterprise " in a dogfight . Cid tells Cecil to take the wheel and return to the Overworld , while he would close the hole . Cid takes a leap of faith that nearly ends his life and Cecil ' s party escapes on the " Enterprise " . They take it to Baron where Cid ' s workers attach a hook to the " Enterprise " so it can carry the party ' s hovercraft . The party can now reach Cave of Eblan and the Adamant Isle Grotto . Musical themes . The theme that plays when a player is piloting the " Enterprise " is called " Airship " , which is the same theme used for all airships in " Final Fantasy IV " other than the " Lunar Whale " . This song can be found as track 29 on both the original SNES and " Final Fantasy Chronicles " soundtracks , along with an arranged version from the Nintendo DS release on disc two , track 5 of that game ' s album . Etymology . The " Enterprise " alludes to an airship of the same name in " Final Fantasy III " .
