In the realm of Duon, the restless souls of the dead wander, without their physical body. These lost spirits are trapped in limbo and are bound to Duon until their remains are recovered. One day, you are summoned to this realm by a powerful deity, who commands you to aid these souls in retrieving their bodies. Should you succeed, you are granted divine ascension capable of shaping your own fate. If you fail, you will suffer the same fate with these lost souls.

Weeks into your journey, after countless encounters with the lost, you found your mother's soul, who vanished mysteriously a decade ago. She, too, is trapped in Duon. But instead of asking for her body to be found and her soul freed, she pleads with you to let it remain hidden, wanting to use this time to reconnect and heal the wounds of the years lost to her disappearance.
