Jewels of Gwahlur

Robert E. Howard set the story in Hyborian Africa. The Teeth of Gwahlur are legendary jewels, kept in the abandoned city of Alkmeenon, in the country of Keshan "which in itself was considered mythical by many northern and western nations". Conan, following legends of this treasure, has travelled to Keshan and offered his services to train and lead Keshan's army against their neighbour, Punt.
