In his dreams,
Randolph Carter sees a majestic city, but is unable to approach it. After his third time seeing the city, he prays to the gods of dream to reveal its whereabouts, but then it vanishes from his dreams altogether. Undaunted, Carter resolves to beseech the gods in person at
Kadath, the mountain above which the gods of dream live. In dream, Carter consults priests in a temple that borders the
Dreamlands. They tell Carter that nobody knows the location of Kadath, and warn him of great danger should he continue with his quest to reach the city, suggesting that the gods had purposefully stopped his visions. Carter's knowledge of Dreamlands customs and languages makes his quest comparatively less risky than if done by an amateur, but he must consult entities with a dangerous reputation. The Zoogs, a race of predatory rodents, direct him to
Ulthar to find the priest
Atal. In the cat-laden city of Ulthar, Atal mentions a huge mountainside carving of the gods' features. Carter realizes the gods' mortal descendants will share those features and presumably be near Kadath. While seeking passage there, Carter is kidnapped by turbaned slavers, who take him to the moon and deliver him to horrible moon-beasts, the servants of malevolent god
Nyarlathotep. The cats of Ulthar, Carter's allies, rescue him and return him to a port city. After a long journey, Carter finds the carving, recognizing the visage of the gods in traders who dock at
Celephaïs. Before he can act on his knowledge, faceless, winged creatures called nightgaunts capture him and leave him to die in the underworld. Friendly
ghouls, including Carter's friend
Richard Pickman, assist him in returning to the surface by sneaking through the terrible city of the man-eating Gugs. After assisting the cats in repelling a Zoog sneak attack, Carter buys passage to Celephaïs and learns from the sailors that the traders come from Inganok, a cold and dark land devoid of cats. Carter meets Celephaïs' king, his friend Kuranes, who became a permanent resident of the Dreamlands upon his death in the waking world. Longing for home, he has dreamed parts of his kingdom to resemble his native
Cornwall. Kuranes knows the pitfalls of the Dreamlands well but fails to dissuade Carter from his quest. Under the pretense of wishing to work in its quarries, Carter boards a ship bound for Inganok. As they draw near, Carter spots a nameless island from which he hears strange howls. At a breathtaking summit near a quarry, Carter is captured by a merchant he had previously encountered. Monstrous birds fly them over the Plateau of Leng, a vast tableland populated by
Pan-like horned humanoid beings. Carter is brought to a monastery inhabited by the dreaded High Priest Not to Be Described. There, Carter learns that the Men of Leng are the slavers who captured him, and had worn turbans to conceal their horns. He also learns that the nightgaunts do not serve Nyarlathotep, as is commonly supposed, but
Nodens, and that even Earth's gods fear them. Carter recoils in horror as he realizes the masked high-priest's true identity. Carter flees through maze-like corridors, wandering through the monastery in pitch-black darkness until he chances on the exit. After rescuing several ghouls from the Men of Leng, Carter and the ghoul reinforcements attack a moon-beast outpost on the nameless rock. In a nearby city, Carter obtains the services of a flock of nightgaunts to transport himself and the ghouls to the gods' castle on Kadath. After a long flight, Carter arrives at Kadath but finds it empty. A great procession led by a
pharaoh-like man arrives. The pharaoh reveals himself as Nyarlathotep and tells Carter that the city of his dreams is the childhood memories of his home city of Boston. The gods of earth have seen the city of Carter's dreams and made it their home, abandoning Kadath and their responsibilities. Impressed with Carter's resolve, Nyarlathotep grants Carter passage to the city to recall the gods of earth, but Carter realizes too late that the mocking Nyarlathotep has tricked him and that Nyarlathotep's directions have led him not to the city but to the court of
Azathoth at the center of the universe. At first believing he is doomed, Carter suddenly remembers that he is in a dream and wakes. Nyarlathotep broods over his defeat within the halls of Kadath, mocking in anger the "mild gods of earth" whom he has snatched back from the sunset city. == Characters ==
