What is it?
Is the name to a subgenre of fiction books, otherwise called the "sword-and-sorcery" story. It is a story of action and adventure laid in a more or less imaginary world, where magic works and where modern science and technology have not yet been discovered. The setting may (as in the Conan stories) be this Earth as it is conceived to have been long ago, or as it will be in the remote future, or it may be another planet or another dimension. Such a story combines the color and dash of the historical costume romance with the atavistic supernatural thrills of the weird, occult, or ghost story. When well done, it provides the purest fun of fiction of any kind. It is escape fiction wherein one escapes clear out of the real world into one where all men are strong, all women beautiful, all life adventurous, and all problems simple, and nobody even mentions the income tax or the dropout problem or socialized medicine.
