No, I don't think we have brought Oz into the mix yet, but I could be wrong and that's a great point about the worldbuilding regardless. But Oz always feels way more--open than Narnia does, at least to me.

And yeah, I didn't even notice the food prejudice in the context of all the larger biases, but seriously, WTH.

Though I do love the four main characters. I almost typed 'mane,' heh.
