Frieghenart Forest, a flourishing land that was home to 3 tribes of Tanaeki. A forest filled with the laughter of those tribesmen, chirping of birds and the love of nature.
Yet it all changed 10 years ago when a spatial crack opened on top of this peaceful forest. By the time news of this sudden incident reached the ears of the World Association or the Adventurer's Guild, it was too late. And when the help arrived, this forest was all empty and everyone inside dead or missing.
Some said that everyone was pulled into the spatial crack and died there, while some said a few monsters managed to jump out the crack and killed and ate everyone. The end result was obviously a whole lot of nothing, as after solving the open gate, no one thought important enough to use their treasures to track the people killed below.
