In a forested region of the Kingdom of Diment, there was a “city where the fog never clears”.

The city had become a labyrinth from which none who entered could ever return.

According to legend, the city was transformed into a labyrinth by the deep hatred of the archmage Chu Lu Gah.

It is said that great treasure or a great power left behind by archmage Chu Lu Gah lie slumbering in the labyrinthine city.

The story begins in this labyrinth, the City of Ghosts.

Players choose their own story: an adventure seeking the truth of the labyrinth, or an adventure to escape from the labyrinth.
