WAY ****ING IN PROGRESS
Basic ideas-
-Massive world forest, something like Shadoweagle's old Mojena setting
-Shamanic tribes of human beings (possibly along with weirder races... Poison Eaters Tribe?)
-Shamanic magic- Spirit Partners and shamanic warriors and such
-Gods and spirits are very corporeal- none of this invisible deity rubbish. The stone agers worship BIG MONSTROUS MONSTERS.
Spirits- evil spirits and good spirits. Protector Spirits- wolves who take human shapes to protect tribes?
-Evil sorcerors who make pacts with dark spirits and speak to the dead (I love sorcerors.

)
-Big-ass creatures
I dunno', I only have vague theories as of yet.
