GROGNARDIA: Pulp Fantasy Library: Quest of the Starstone:
While C.L. Moore created numerous characters over the course of her decades-long writing career, her two most popular creations are the medieval French warrior Jirel of Joiry and the futuristic ne'er-do-well Northwest Smith. I've written about both of them before in this space and with good reason. I consider both Jirel and N.W. to be among the most memorable characters of pulp fantasy, right up there with John Carter and Conan. These characters are not only interesting in their own rights, but very influential to boot, becoming prototypes for later fantasy and science fiction characters (It's pretty clear, for example, that Northwest Smith served as a significant inspiration for George Lucas's Han Solo).
