Magitek Research Facility The Magitek Research Facility is an unrevisitable location in " Final Fantasy VI " located in the imperial capital of Vector . It is where experiments on espers are carried out , and is where the empire ' s Magitek weapons are produced . The facility was developed sixteen years ago . Completing the location in the mobile / Steam port earns the Terra ' s Truth achievement . Story . The Returners infiltrate the facility with the help of a Returner member stationed in Vector , and make their way through the facility to try and find the captive espers used to power the Gestahlian Empire ' s Magitek weapons . They spy Kefka torturing two espers before throwing them into a garbage chute , laughing at the power he has gained from them , as well as hinting at his plans to restore the Warring Triad using the espers ' magic . After acquiring the help of the two as magicite , the Returners climb up to the main lab where six espers are held captive . The Returners shut down the machine , but the espers are already too weak from the experiments , and turn themselves to magicite . Cid arrives and speaks to Celes and Locke , inquiring about rumors that Celes is an imperial spy . Kefka appears and insists the rumors are true , and has two imperial soldiers attack the group . To prove her loyalty , Celes teleports the imperials , herself and Kefka away . The fighting damages machinery in the room that begins to explode , and Cid and the other Returners flee to a mine cart . The Returners ride it to safety , meeting up with Setzer and escaping Vector on the " Blackjack " . The events trigger a shift in the Third Gestahlian Campaign — the empire ' s supply of magic is cut off , but they acquire the knowledge of magicite as a superior source of magical energy than the forced extractions from live espers . With this information , and due to the devastation caused by the Returner raid , the Magitek Research Facility is dismantled soon after , but pieces of it make up the debris used to form Kefka ' s Tower in the World of Ruin . Areas . The first area of the facility is the Magitek Factory , where the empire ' s weapons are produced . Many one - way lifts , cranes and conveyor belts make for a complex maze , and there are a handful of hidden passages . A garbage chute where Kefka dumps the espers Shiva and Ifrit has two doors : one to a save point , the other leads to a long stairwell that leads up to the Magitek Research Facility , where the espers are being kept . A lift from the facility leads to a mine cart track leading out of the facility . Development . One of the greatest challenges in making " Final Fantasy VI " was the rail scene where the Returners ride their way out of the Magitek Research Facility . Square used the Super Famicom screen support mode known as Mode 7 and painstakingly illustrated the graphics one dot at a time to create a mock 3D effect . Although producing these graphics was a huge undertaking , the results were far rougher than the developers had hoped . In the end , this section didn ' t leave a lasting impression as had been intended . Musical themes . " Magitek Research Facility " , also known as " Devil ' s Lab " in " Kefka ' s Domain " , is the background theme of the Magitek Research Facility . Other appearances . " Final Fantasy XIV " .
