 The only true "natives" in the book, the Ramapithecus are a race of small, somewhat fragile seeming hominids, believed (at the time of writing, though no longer) to be the original ancestors of modern humanity.The "Ramas" were enslaved by the Tanu when the exotics first arrived on the planet, through the use of Torcs with control and mindspeak circuits.A derivative form of these circuits were used to create the Gray Torcs and also used in Silver Torcs, derived from the Tanu's own Gold Torcs.
