Hugo Award-winning author and SFWA Grand Master Philip José Farmer launched the Khokarsa series (sometimes called the Ancient Opar series) in 1974 with the novel Hadon of Ancient Opar, followed by a sequel, Flight to Opar, in 1976. The series was a tribute to the lost-world tales of Burroughs and Haggard, and a testament to Farmer’s formidable skill at meticulous and exhaustive world building. Though Farmer planned an expansive series using Khokarsa, Ancient Opar, and the lost city of Kôr as settings, other writing projects delayed those plans until 2005, when he authorized Christopher Paul Carey to complete The Song of Kwasin, the third novel in the series, using Farmer’s partial manuscript, outline, and extensive notes. In 2008, Carey completed the manuscript and Farmer approved it for publication, and in 2012, The Song of Kwasin appeared alongside the first two novels of the series in the omnibus Gods of Opar: Tales of Lost Khokarsa (Subterranean Press). Since Farmer’s passing in 2009, Carey has continued to write authorized tales in the Khokarsa series with the blessing of the Philip José Farmer estate.
