Primal Rage
When "Primal Rage II" was cancelled, Atari allegedly felt it necessary to somehow present the story for the sequel in one form or another. Thus, in 1997, a novel called "Primal Rage: The Avatars", written by John Vornholt, was published by Boulevard Books. The book tells what happened to the dinosaur gods 65 million years ago, and then moves into the main story of the gods' reign on Urth renewed, then the beast Necrosan appears. The book also focuses on fleshing out the world of "Primal Rage", and does so by bringing "the Avatars" to the forefront of the story, they being the humans chosen by their respective gods to be their shamans or other titles of nobility.
