Opar (fictional City) - in Farmer

In Farmer

Opar is also the setting of Philip José Farmer's novels Hadon of Ancient Opar (1974) and Flight to Opar (1976), which expanded the idea of Opar into a pre-historic world (some 10,000 years ago) in which Africa had two huge linked inland seas, which were the cradle of a pre-Egyptian civilization. This primeval empire was based on an island in the more northern sea, taken to be Atlantis in the Tarzan books; the city of Opar, located on the more southerly sea, is portrayed as having been a small back-water in this much larger realm, called Khokarsa. Farmer's novels mix characters from the Tarzan series (Farmer maintained that the character Sahhindar is the time traveler John Gribardsun from his novel Time's Last Gift, in which it is strongly hinted that Gribardsun is in fact Tarzan) and H. Rider Haggard's Allan Quatermain series ("Laleela" and "Pag", here renamed "Lalila" and "Paga").
