This setting has a cool Tekumel-like vibe yet is far more accessible (no language courses required..). Its good to get play out of medieval Europe and into something that feels like a cross between the ancient Americas and Polynesia. Art is very appropriate to the subject matter, and suitably up for interpretation. If the setting and background were fleshed out just a little more it would be a 5 from me, as it stands it would take a lot of work from a GM to put meat on the bones presented here. However some folks may see that as a positive in customising the setting.
