We now stood at the threshold of Ghost Valley, perched precariously on the slopes of Gwanghwa Mountain and an uneasy silence settled over our group. It was midday outside, where the sun shone brightly and the world felt alive.The sun blazed brightly outside, its rays illuminating the vibrant greens and life surrounding the base of the mountain. But as soon as we looked into Ghost Valley, it was as if we were staring into another world entirely. The sky above the valley was pitch-dark, almost as if it had swallowed all light. Heavy clouds twisted above, churning like a storm was on the verge of breaking, yet not a single drop of rain fell. There was no rain, no thunder—only an oppressive stillness of the air, like the calm before a deadly tempest.
