winged monkey ghost from outer space?

That should teach me not to try to skim through posts quickly.

Well, if the object is a stone age setting, then go colder and drier with megafauna and cave men and/or giants. Cities of Sar-aigu, could work as the civilization and there should be some reptilian? civilization in the barrier swamp at some point. maybe that's sar-aigu too. 15-50000 seems a more likely timeframe.

Magic should really develop hand in hand with technology, much as science and medicine did in the real world.

Curious of what races would be around besides humans though as well as what classes would be acceptable to be around.Wokans, druids/shamans, druids, barbarians, clerics even, possibly almost every low tech material class and bards in the form of oral lore keepers.

I could see the idea of evolution being the core of creation, the fact the neanderthals were around and one of their own became a Immortal and humans also existed as well, so they could have a common ancestor and from what I understand the primal Immortals they don't have a true form, they just have forms so Ixion might appear human while a elemental cult might see him as a fire elemental like being of the sun.

Also what Immortals were of elemental origins? They probably be common in a stone age setting as nomadic tribes try to find new stomping grounds though what immortals are active then anyways?

Also maybe evolved reptilian races? Tie the carnifex into it, they might be those who 'uncovered' the secrets of evolution thus creating reptilian races through magic and temporal warped selective breeding.
