The Book of Darkness, or the Chronicles of the True Land, is a cycle of works that depict episodes from the history of a strange world which, geographically, matches Earth—yet has a somewhat different history. And perhaps also different physical conditions. The first and main thing is that magic exists in this world. The second, less noticeable though possibly even more important is that, in this world, those whom mortals call Gods are actually present. And all of them at the same time.
