This is an awesome replacement for shifter culture. just rip them out of the forests and throw them on islands. I am seriously thinking of doing it the next time I run Dungeons and Dragons, everybody seems to have fallen in love with shifters in my gaming group, so it's an aweshum fit. Have you looked at the spirit shaman class? perhaps you can make some substitution levels so that it is tweaked more towards the setting your playing with. For this class, ‘spirits’ are defined as the following: Incorporeal Undead, Fey, Creatures in Astral Form or with Astral Bodies, Creatures with the ‘spirit’ subtype (see Oriental Adventures), Spirit Folk, Telthors, & spirit creatures created by spells such as Dream Sight & Wood Wose. At 20th, they become Fey type. Me thinks that the kind of conflict that goes on in Maori mythology is very much the kind that goes on in the conflict of human versus fey in Dungeons and Dragons, meaning the Natural versus the Alien. Some fey are evil, most aren't and thier conflict with humans is because the rules for either are abbhorent to the other.
