Natbakh

Natbakhs are native to the peaks and subterranean caverns of the windswept dimension of Leng and haunt the dark skies of that nightmare realm.

Nightmare Eruptions

In places where the boundaries between Golarion and Leng are thin, such as the depths of the Kodar Mountains, natbakhs have a particularly horrifying method of entering the waking world. If they consume the dreaming persona of someone sleeping near such thin places, they can burst forth from that sleeper's body, killing them in life as well as in their dream, often leaving the now-dead dreamer's home in splinters before flying off to build a lair in the mountains. Such "nightmare eruptions" are rare, but it doesn't take many natbakhs to leave a mark in a region unprepared for their arrival.
