Jonathan's Numenera Game
The tallest of the mountains in the Black Riage at 23,000 feet, Mt. Zanlis is also known as the Dark Master. Most of those who dwell within 100 miles of the peak believe it to be some kind of living being possessed of great power, though whether god or devil none can say. Aeon Priests investigating the area suggest that the mountain’s core might be artificial, housing a machine core with the ability to affect reality on a fundamental level. The potential motives, goals, or outlook of such an intelligence remain entirely conjecture. However, the locals talk of green rain, acidic hail, other weird weather, unexplained lights, changes in gravity or the flow of time, the sudden appearance of strange creatures on the mountain’s slopes, and the disappearance of travelers, hunters, or others that got too close. And yet some explorers have traversed the region many times without incident.
