Blank spots.....if that's where you plan on heading then I'll bite.To assume that Eris is the only God/Goddess is almost a crime. If Eris were the only goddess then why did she wait so long to try and plunge the world into chaos? And whose to say that wasn't her fist attempt? Did she repeatedly set herself up to fail? Or perhaps since she is so powerful she tried winning and found it boring and started everything over. If she isn't the only god then have the others forsaken that world? Did they leave them with powerful relics out of carelessness or so that they could defend themselves? Maybe her Chaos Realm isn't even separate from the 'earth'. Eris treats the universe like a playground, if we really want to dig deep perhaps we should confront the idea that Eris created all of it, if you haven't already. She gives the people free will and sets situations up over and over again just to see what would happen. Which brings us back to the other gods, did they trap Eris in her own mind or maybe a prison designed to make her happy. If there are no other gods then we should begin to wonder that perhaps Eris is even Eris. She tells Sinbad that she is and comments how the temples depict her doesn't do her justice. The priests could've gotten it wrong but then again if they actually got it right then who or what is Eris? Is she or it a greater evil using Eris's name or maybe something else entirely.

Eris seems to be the only divine entity, as we see no evidence of any other entity. There is no religious mention of other beings anywhere in the film, they obviously don't make an appearance, and the only two sources of "magic" are Eris and the Book of Peace. You say it's a crime to think there are no other Gods, but I see no reason to believe that there are. I like the idea that the other Gods might imprison Eris in her mind, and the many ideas that might stem from there, but if we're going to look at every possibility from matrix to inception, we'll go insane. There are simply too many possibilities to count. However, most of them have no basis in the film, and through Occam's Razor, I believe we should look at simpler things.
I think that it's quite likely that Eris created the entire universe. She bathes in stars. That suggests the power to bend the very universe to her will. However, it's also quite possible that Eris is simply using the form of stars, and can't literally control the universe to such a degree. Just how much Eris has created, and how great a power she has is quite a mystery, as nothing in the movie really "challenges" Eris. Her power might be infinite, or she might just be a cocky planetary Goddess.
