" Pre Conan REH. Only a few published stories, some promising fragments, drafts, etc. Despite that it's essental sword and sorcery, if only for Shadow Kingdoms which many believe to be the first s&s story --at least american. Kull is a great brooding King who spends time thinking about cosmic, Lovecraftian things, the nature of time, etc. REH examines his great (or not so) theme that civilization is less 'true' than the barbarian life, there are picts, lost civilizations (Kull being an exile of Atlantis), old Gods, assassination plots, crazy, crafty wizards and good old gory fights. REH is finding his voice here and hitting his stride. He's all over the map, but he has a lot of vibrant stprytelling energy. "
