The underworld is a fictional location in the Dream Cycle of H. P. Lovecraft. It is described in detail in Lovecraft's novella The Dream-Quest of Unknown Kadath (1926).
The underworld lies beneath the whole of the Dreamlands and has a few entrances to it in various places. It is dimly lit by a mysterious phosphorescence known as the "death-fire". The underworld is inhabited by a variety of horrors, the most common being the ghouls.
After a moment something about the size of a small horse hopped out into the grey twilight, and Carter turned sick at the aspect of that scabrous and unwholesome beast, whose face is so curiously human despite the absence of a nose, a forehead, and other important particulars.
—H. P. Lovecraft, The Dream-Quest of Unknown Kadath
The ghasts are a race of fearsome humanoids that live in the vaults of Zin. They are much larger than a man and have a vaguely human face, albeit missing a nose. Their skin is rough and knotty. Their senses are unusually acute; they can see in the dark and have a strong sense of smell. They hop about on a pair of hooved, kangaroo-like legs, and are swift, strong, and agile. They have also been described as lacking a forehead. Ghasts prefer to dwell in complete darkness and have no tolerance for natural light — sunlight will kill them instantly. Otherwise, the dim, pale glow of the underworld seems to cause them little harm.

she said. Then there was a
man’s voice, saying how the flesh and muscle would be
much more tender if you
cook it at a certain temperature. But he had a certain
lust in his voice.
Disturbing actually, there was a fireplace, but instead
of a fire a TV took its
place, with perfectly cooked meat. I knew it was human.
Now the lady began
crying so hard. Out of nowhere she appeared in front of
me, next to the TV.
With her brain fully exposed. In shock I jumped back.
The door flew open. The
man with the lustful voice shot a look at me. He began
evaluating with his
eyes. Imagining how I would taste. I felt it in my
bones, personifying a
doctor. I believe he was talking to someone, but I
didn't see who. Out of the
shadows, came a gargantuan man covered with dry scaled
blood. As if he enjoys
his kills stick to him represents who he is. Limp, he
barged into the room. It
was the lady he wanted, to me he was oblivious. She was
crying and holding
something in her hands. I sat there trying to figure
out what I was it was
witnessing, where I was, how I got who I am. Sweat
pouring out of every gland.
Then a glitched sound stole my attention. A sound came
from behind the lady.....
