You will find that this sidequest is similar to Setsuna’s, as you simply need to run around and talk to people in order to finish it. To begin, put Aeterna in your active party and go to Tenderville. Enter the only house only the north side and talk to the NPC inside, who asks of you a favor. He wants you to find the president of the Magic Consortium, which he says might be in the Nameless Village.
After the conversation has finished, get in your airship and set off to the western side of the world. You’re looking for an island with a town on it; the island’s name is the Isle of Misfits. Enter the town and go into the house on the western side to find an old man. You find out some things and as you exit the house, you hear a monster’s howl. Go to the watchtower in the same town to see a giant monster that looks like the Stout Sheep walking around.
Return to the old man on the western side of the village to talk to him again, then head for the front gate. Get ready for a battle against the giant monster…or not, as something happens to it. Once more, talk to the old man in the village and Aeterna will give him a stern talking to because of all of the actions. Now you can go back to the man in Tenderville to finish the sidequest and get your reward, the Gearadia Spritnite for Aeterna.
Obtained the Gearadia spritnite.
