An insane magician sinks the Golden Kingdom underground, causing its king to emerge and offer his treasure to anyone who can defeat the magician. However, the king soon crumbles to dust. Guilds are motivated by the promise of treasure and venture into the dungeon to find the magician. Unfortunately, Laios, the leader of one guild, and his team encounter a dragon that wipes out the whole group, including Laios' sister, Falin. Despite their loss, Laios, along with Marcille, an elven healer, and Chilchuck, a halfling thief, immediately return to the dungeon to save Falin.
