The Primal Mouth is a particularly powerful spawn of Abhoth who has taken residence in a cavern in the Midnight Mountains connected to its progenitor's lair, where it has gathered a monstrous cult of gugs. It is curious about the lands above and seeks to open a portal between its lair and a large city in the surface.
