Torneko (aka Taloon) from Dragon Quest IV was a merchant and treasure hunter who always dreamed of owning his own shop. Having defeating the evil along with other heroes, he returned to Endor to work peacefully. Some time has passed and after growing successful in this town, Torneko grew anxious. Hearing rumors one day about a "Mysterious Dungeon", Torneko meets with the king to ask permission to set up a new shop, closer to this Mysterious Dungeon. By exploring this cavern and returning safely with the prizes, Torneko hopes to become the most successful merchant in the world.
