Narshe Mines The Narshe Mines refers to two dungeon s in " Final Fantasy VI " , located in Narshe . The moogles ' home and the frozen esper Valigarmanda are found deep within the caves . Story . The Gestahlian Empire sends in a force consisting of Biggs , Wedge , and Terra to capture the esper recently discovered in a new mineshaft . After fighting their way through the Narshe guards they find the object of their search . The esper resonates with Terra , killing off Biggs and Wedge and destroying the Slave Crown that was robbing Terra of her free will . Arvis recovers Terra , but she is pursued by Narshe Guards . Terra flees into the mines and loses consciousness when a floor collapses . Arvis sends Locke to rescue her , and with moogles ' help he fends off the guards and escapes via a secret entrance outside of town . Terra uses the same entrance to sneak back into town later with Edgar and Banon . The moogle Mog can be recruited in the mines in the World of Ruin . Locations . The inner mines are accessed north of the main town , and is where the frozen esper Valigarmanda is found at the beginning of the game . This passage leads up to the snowfields above the town where the Returners battle an Imperial force led by Kefka . The frozen esper is relocated to a bluff just past the snowfields after the game ' s introductory sequence , and remains there for the rest of the game . If the player returns and defeats the esper in the World of Ruin , Valigarmanda opens a new path leading to the Yeti ' s Cave where Umaro can be recruited . The outer mines lead from just outside the entrance of town to the back door of Arvis ' s home . The outer mines house a moogle camp and a " checkpoint " room where a glowing orange light traces a path through a maze — the party must follow the path exactly to proceed . Straying will cause a field of blue light to surround them , and the player must " tag " the glowing orange light to disperse the field , or else face an enemy and be teleported back to the entrance of the room . Quests . Rescuing Terra . A minigame where the player can control and position three parties plays out . The parties include Locke , Mog and the Ten Moogles . Other units start from the bottom and approach Terra at the top . Regular encounters are against a Silver Lobo and a Megalodoth .

In the World of Ruin , Mog can be found in the moogle cave in the depths of the Narshe ' s mines and finding him will prompt him to join or rejoin the party depending on the action the party took in the World of Balance .
