"The Silver Key" is part of a nonsequential series of stories that focus on either the character Randolph Carter, the dream world, or both: "The White Ship," "Celephais" (1920), "The Cats of Ulthar," "The Statement of Randolph Carter" (1920) "The Other Gods" (1921), "Through the Gates of the Silver Key" (1932, with E. Hoffman Price). The novel The Dream-Quest of Unknown Kadath is the centerpiece of the Randolph Carterdream world tales. In it, Carter sets out to find the fabled city of Kadath and has a variety of fantastic adventures. Although these stories are commonly thought to be inferior to those that focus on Lovecraft's Cthulhu Mythos, "The Silver Key," "The Cats of Ulthar," and The Dream-Quest of Unknown Kadath still have many fans.
