also finds a lithograph of a dragon, which Friday tells him is a clue to the treasure. Before he can leave, Kayla, Ink, and Wally show up and hold Friday hostage until Nigel hands them the lithograph. Nigel's heroics earn him a place in the court of Duke Mercator, who orders him to go and defeat an old wizard, Mir, who is locked in a tower nearby and who has been terrorizing the town and extorting the Duke. Nigel braves a crypt and the wizard's tower and faces him in single combat. Defeated, Mir confesses all he knows about King Nole's treasure and then explains that the Duke is his brother and had been using him as a scapegoat for years. Nigel returns to the Duke and is about ready to confront him when he is tossed into a dungeon. While imprisoned he finds out that the princess of Maple, his home country, who had been a guest at the castle, has been taken away by the Duke's dragon-like henchman, Zak. He manages to escape to find the castle knights in open revolt and ships stuck in the harbour because the lighthouse in Ryuma is broken. Nigel saves Arthur, the Duke's general, and is given the key to the Greenmaze, where the Sunstone can be found, the gem that powers Ryuma's lighthouse. Nigel navigates the maze despite the best efforts of troublesome gnomes and restores the lighthouse. He then takes a ship to pursue the Duke. He makes landing up the coast of the island at Verla, which has practically become a ghost town. The Duke had enslaved the population of the town and forced them to work in nearby mines searching for a legendary treasure. Nigel frees the townspeople, and they give him a legendary sword they found but had hidden from the Duke. Nigel continues through the mine to find the Duke sailing, via rafts, across a lake to an island temple. Nigel finds a way over and navigates through the labyrinth to fight the Duke but is caught off-guard by Zak. Nigel is teleported to safety by Mir before the Duke and Zak can finish him off. Mir then proceeds to give Nigel some more information about King Nole's treasure. Mir also gives a magical axe to Nigel which allows him to cut down trees with a single swing of his sword. Nigel retakes his sword in
