Six challengers take on the so-called Mountains of Madness—a range of absolute despair.
About
Introduction An Air New Zealand sightseeing jet disappeared over Antarctica. Following a desperate search by the Antarctic Research Expedition, a massive, unknown mountain range was discovered beyond the coordinates where the radio signal vanished. It was revealed that this uncharted range reaches a maximum altitude of 10,300 meters (specifically 10,363 meters), making it the highest peak in the world, surpassing Everest. A primary expedition team was formed to achieve the feat of the first human ascent. They never returned. Someone dubbed it the "Mountains of Madness." Now, there are those reckless enough to challenge those violent peaks. What will the explorers encounter atop the summit of the gods? You are members of the secondary expedition following in their footsteps. The team consists of 6 members: 2 explorers (players) and 3 NPCs. While there are omens suggesting encounters with mythos entities along the way, the real trial begins after the summit. The scenario boss, the mythos entity, is the "Mountains of Madness" itself. The mountain range, exceeding 10,000 meters, was actually a colossal living organism. The Mountains of Madness, dormant for ages, awaken due to the explorers' ascent. When they realize the true nature of the mountain they have conquered, can the explorers, gripped by madness, return alive?
