"Heroic fantasy" is the name I have given to a subgenre of fantasy, 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.
