Two young adults return to their lost hometown in search of truth and to bring back what they hold dear. The town of Hallfein was once situated at the border of three provinces, and thrived thanks to mining and trade.

The former hopes to restore the shop left behind by her missing grandfather, and the latter seeks to investigate the mementos left to him by his father. While their reasons for returning differ, they share one common goal: uncovering the cause of the townspeople's mysterious disappearance. After meeting in their hometown, the two embark on a journey together to seek the truth, unaware of the encounters and revelations that await them...
