A WITCH SHALL BE BORN is one of the original sword and sorcery novellas by Robert E. Howard about Conan the Cimmerian. It was written in only a few days in the spring of 1934 and first published in Weird Tales in December 1934.
Queen Taramis of Khauran awakens one day to find her identical twin sister, Salome, staring her in the face. As an infant, Salome was deemed a witch due to a crescent-shaped birthmark on her chest. This birthmark was believed to be a sign of evil, so she was left in the desert to die. However, a magician from Khitai (China) found Salome, brought her up, and instructed her in the art of sorcery.
