"The Dream-Quest of Unknown Kadath" follows Randolph Carter, a dreamer who ventures deep into the Dreamlands seeking the majestic city of his visions, which the gods have forbidden him to behold. Along his perilous journey, he encounters strange races—Zoogs, ghouls, night-gaunts—and navigates alien landscapes, dark temples, and forbidden cities. Pursued and manipulated by the crawling chaos Nyarlathotep, Carter must endure betrayals and horrors until he finally confronts the truth about the city of Kadath and its divine guardians.
