GIBBERING MOUTHER
Of all the terrors created by foul sorcery, gibbering
mouthers are among the most wicked and depraved.
This creature is the composite eyes, mouths, and
liquefied matter of its former victims. Driven to insanity
by the destruction of their bodies and absorption into
the mouther, those victims gibber incoherent madness,
forced to consume everything in reach.
Amoeboid Form. The gibbering mouther's body is
an amorphous mass of mouths and eyes that propels
itself by oozing forward, fastening several mouths
to the ground and pulling its bulk behind. Though
it moves slowly, it swims through water, mud, and
quicksand with ease.
Mouths of Madness. When a gibbering mouther
senses prey, its mouths begin to murmur and chatter,
each with a different voice: deep or shrill, wailing
or ululating, crying out in agony or ecstasy. This
cacophonous gibbering overcomes the senses of any
creature that hears it, causing most to flee in terror.
Others are overcome with madness or stand paralyzed,
fixated on the horrific creature as it oozes forward to
consume them.
All-Consuming. Driven to devour any creature it can
reach, a gibbering mouther flows over victims transfixed
by its mad ranting, its multitudinous voices temporarily
silenced as it gnaws and swallows living flesh. The
monster liquefies stone with which it comes into contact,
hindering creatures that overcome its gibbering and
attempt to flee.
A gibbering mouther leaves nothing of its prey
behind. However, even as the last of a victim's body is
consumed, its eyes and mouth boil to the surface, ready
to join the chorus of tormented gibbering that welcomes
the monster's next meal.
