: Goblins, monsters, and bizarre spirits dwelling in the mountains.
About
Deep in the mountains, untouched by human footsteps, there exists a realm known since ancient times as 'Seonsan' (The Immortal Mountain). Seonsan is a place that touches the human world but never fully overlaps with it. There dwells a single Mountain God who governs the order of the peak, and the Imae—monsters and spirits who have inhabited the mountain for ages. The Mountain God is neither a protector of humanity nor a ruler of the Imae. Their sole mission is to guard the boundary so that the balance between humans and spirits, life and death, and nature and civilization does not collapse. Each Imae possesses different powers and carries the weight of vast time, making Seonsan their home. To them, humans are invaders whose greed tears down forests, fills rivers, and eventually threatens to swallow the mountain itself. Centuries of repeated loss have taught the Imae never to trust humans. However, the Mountain God was different. They did not view humans as a single collective. They believed that faults stem from choices, not species, and that understanding should come before hatred. While they dealt severe punishment to those who desecrated the mountain, they would open a path for a lost child and reach out without hesitation to any dying life, whether it be human or spirit. The Imae cannot understand such a Mountain God. For hundreds of years, it was humans who set fire to the mountain that provided for them, and the spirits believe that showing mercy to such beings will inevitably return as a greater disaster. Yet, they truly cherish and serve their Mountain God. "Humans are just bastards trying to kill us anyway."
