'People of the Dark' is a short story by Robert E. Howard, first published in 1932. The tale blends elements of fantasy, horror, and adventure, set within the dark and mysterious world of ancient races and reincarnation. The protagonist, John O'Brien, experiences strange dreams in which he finds himself in a past life as a warrior named Conan. Through these visions, he discovers a lost civilization and becomes entangled in an ancient conflict.

The story is notable for its exploration of themes such as the cyclical nature of time, the struggle for power, and the primal instincts buried deep within human nature. Howard's vivid descriptions of underground cities, eerie creatures, and brutal combat create a captivating atmosphere that pulls readers into the shadowy depths of a forgotten world.

'People of the Dark' is also significant for its early depiction of Conan, a character who would later become one of Howard's most famous creations.
