|Japanese name||モアパ Moapa|
Felix's party arrives at Shaman Village, in search of a Psynergy that would allow them to enter Jupiter Lighthouse. However, they find that the entire village has locked themselves in due to a fear of outsiders. The only house that is open in any way is Moapa's. He introduces himself as the chief of Shaman Village. When Felix's party presents the Shaman's Rod, he recounts the legend that he is to give the Hover Jade to whoever gives him the Shaman's Rod. However, when Felix's party attempts to do so, he hesitates, reluctant because Felix's party is a group of foreigners who are not from the allied town of Contigo.
At the suggestion of his knights, he takes the party to a large Wind Stone, ordering the Adepts to make the nearby wall of sand disappear as a test. Sheba, as a Jupiter Adept, is easily able to do so by casting Whirlwind on the Wind Stone, leading Moapa to believe that Sheba is of Contigan descent. Despite this, Moapa still refuses to hand over the Hover Jade, as there is another test. However, he is reluctant to let them take it as the test's winners have been male, while Sheba is a girl. However, Felix's party convinces Moapa to allow them to take the test.
Moapa then leads the Adepts to Trial Road. He explains that the test is a recreation of a legendary battle between the heroes of Contigo and Shaman Village, wherein the two raced to the top of a mountain, then engaged in a fierce battle. He lets the Adepts know of the requirement of leaving their weapons and/or armor in chests at key points, making the intial portion a race, as the winner can continue with more armor.
With the explanation complete, Moapa and his two knights race Felix's party to the top of Trial Road, then engages the Adepts in battle. Felix manages to successfully defeat Moapa's party, granting him the Hover Jade in exchange for the Shaman's Rod. Upon returning to town, Moapa allows the townspeople to come out of hiding, but expresses regret that he never learned the group's names. Hearing of this, Felix's party goes to Moapa's home and gives their names, which Moapa states will be remembered by the villagers.
