Stigma of Corruption: Nightbound Courier

The story begins in a village where a young man named Caius has a strange dream: he returns to his hometown after a long, bloody war with demons to finally settle down to a peaceful life, build his own trading post, and become a great courier just like his adoptive father, and that even his childhood friend Lilian, who grew up alongside him, would envy him. But it soon turns out that almost all the villagers have recently begun having strange dreams, and rumors have started circulating that this is somehow connected to a new dark threat—an impending demon invasion—and the mysterious appearance in the village of a suspicious fortune-teller… Young Caius and Lilian decide to find this woman and try to find out from her what is really happening in the village and what is coming their way.
