Ghasts
Ghasts are predatory creatures of the Vaults of Zin in The Dream-Quest of Unknown Kadath. Their vaguely human faces, powerful hopping gait and pointed hooves distinguish them from both ghouls and gugs. They are hunted by the giants above them, yet emerge during the gugs’ sleep to attack whoever they can find. Two encounters with ghasts shape Randolph Carter’s escape from the underworld.

The Vaults of Zin
The ghasts inhabit the darkness of the Vaults of Zin, reached through a cavern near the gug cemetery. The entrance is part of a larger system of underground territories rather than an ordinary surface cave.

Gugs enter the vaults to hunt them and post a sentry at a narrow passage. Ghasts watch for opportunities to escape that containment. Their raids tend to coincide with the giants’ sleeping period, when the streets above offer both prey and a route away from their hunters.
The narrative presents the gugs’ predation and the ghasts’ retaliatory aggression together. A ghast may be another creature’s food without ceasing to be dangerous to a human traveler.
Appearance and movement
The first ghast Carter sees is approximately the size of a small horse. Its face has a disturbing human resemblance despite lacking a nose, a forehead and other familiar features. Yellowish-red eyes become visible in the cavern before the body emerges.
Long hind legs produce a hopping movement compared with that of a kangaroo. During the battle with the gug sentry, hard pointed hooves become explicit weapons. A faithful depiction therefore needs more than a vaguely humanoid cave animal: the distinctive face, powerful hindquarters and hoofed attacks belong together.
Their proportions and unhealthy-looking surfaces disgust Carter. The account supplies no stable color chart, complete skeleton or exact measurements of every limb. Those details in illustrations remain artistic interpretation.

Light tolerance and senses
Real light is fatal to ghasts, but the gray twilight of the abyss is not equivalent to daylight. They can endure that dim environment for hours, which permits excursions from the deepest vaults into the cemetery and city.
Their sense of smell is acute enough to make Carter and his guides fear detection. Even if the party remains unseen, its scent could attract predators along the escape route. Darkness consequently offers a human visitor little protection.
The distinction between deep darkness and tolerable twilight is operationally important. It explains why the creatures can conduct raids above their usual territory without contradicting their vulnerability to light.

Sounds and social behavior
Ghasts communicate or interact through harsh coughing sounds. Their calls contrast with the gugs’ lack of a speaking voice and the ghouls’ own distinctive speech. Carter can hear a ghast above him in the tower before he can see it.
Pickman’s account describes them as very primitive, violent and cannibalistic. They attack ghouls as readily as gugs rather than recognizing the distinction as a reason for restraint. These are descriptions within the narrative, not evidence of a detailed system of ghast laws, kings or organized religious practice.
Their group attack nevertheless demonstrates practical cooperation or converging aggression. A dangerous opportunity can draw many of them against a much larger enemy.

The raid beside the cemetery
Carter and the three ghoul guides hide as ghasts begin emerging from the vaults. Their numbers grow to about fifteen. Because they show no wounds from fighting, the guides infer that the gug sentry was sleeping when they passed it.
The guard eventually appears, extending its divided arm and enormous paws from the cavern. Before it can stand, the ghasts rush it from several sides. Bites and hoof blows keep the contest close to the ground, where the giant cannot use its full height as effectively.
Some ghasts are caught by the gug’s fanged mouth, but the group gradually drives the struggle back into darkness. The receding noise allows Carter’s party to cross the sleeping city. The travelers owe their opportunity to a conflict in which neither side is acting to help them.

The ghast in the Tower of Koth
A separate ghast has entered the tower before Carter’s party. During the climb, a cough from above reveals its presence. The ghouls push Carter against the wall and prepare the heavy slate gravestone they have brought for opening the final trapdoor.
The descending creature’s hoofbeats and breathing become audible. When its eyes appear near the next step, the guides strike with the stone and kill it. Their ability to see in darkness permits a defense Carter could not have managed alone.
Later, the corpse tumbles down the stairs after an unseen disturbance. The travelers cannot identify what moved it, but every plausible explanation means danger nearby. The incident accelerates their desperate effort to lift the exit door.

Ghasts, ghouls and gugs
The similar names can conceal sharply different roles. Ghouls guide Carter, communicate with him and obtain food from graves. Gugs are giant city-builders who hunt ghasts and are restricted by a divine curse. Ghasts are the hopping predators from the lower vaults that can threaten both groups.
The distinctions matter more than a simple ranking of size or strength. A small party of ghouls survives by knowledge and coordination; a giant sentry is vulnerable while crawling through a confined entrance; a ghast becomes deadly when it controls a narrow passage in darkness.
Within Carter’s journey, the ghasts make the underworld feel inhabited by competing forms of life. Their movements have consequences that exist independently of the human quest, and the traveler must adapt to those consequences to escape.
