The largest and most dangerous lake, fed by the Elmynfrosk river from the north. Naihim's center is effectively impassable—the stillwater effect is so pronounced that even objects thrown in arc slowly rather than splash. Local satyr tribes consider the lake sacred or cursed (the distinction is unclear) and avoid its shores entirely.
What makes Naihim unique is the sound. On still nights, those near the shore report a low, constant vibration—not quite a hum, more a pressure in the ears. The sound comes from the water itself, as if something vast is holding very, very still at the bottom.
