The Mount of Black Fire is an extraordinary mountain in the Tusk Mountains. Unlike other active volcanoes, this mountain spews forth a dark ebony flame. Even more strange: This ebony fire puts out regular fire. This unstable fire comes from overlapping gates going to the Plane of Fire and the Void inside the mountain.
Of particular interest is the attraction of the Blackfire Adepts, a group of powerful individuals associated with an arcane cult. The Blackfire Adepts are drawn to the Mount of Black Fire due to its connection to distant planes and the eldritch energies it possesses. However, despite their efforts, they have not yet discovered a means to fully master or control this unique and enigmatic power source.1
