Here's a story I've been struggling with for some time. It's a bit complicated, but here goes: Imagine if this whole world was created in the image of Heaven. The trees, the sun, the animals, even the people are "angelic". If you look at a normal version of an angel, it looks suspiciously like a human with wings. And now image there's another world out there (or realm, dimension, whatever) that's created in the image of Hell. We're talking black, spiky mountains, volcanoes, red sky, nightmarish creatures and so on. The people there have dark red skin, yellow eyes, sharp teeth, claws, the whole thing. In other words, they look like demons. Even so, that world is not evil any more than ours is. It's just different. I don't mean to be racial, but imagine if a caucasian who has never been outside his all-caucasian home town went to a city full of black people who spoke a different language, and you see what I mean. Everything is different. The culture, the music, the food, even the movies are different. But neither city is goor or evil. They are just different. Now imagine if one of these worlds found the other. People do what people do best, and a war would break out for protection/control/resources/defense/whatever. This would cause millions, even billions of people on either side to be killed, so a small company is doing everything they can to prevent the two worlds from knowing each other. In short, they carefully choose the genetically best parents from either world and have them donate sperm and eggs (not always willingly). They then use these resources to create geneticaly superior children with a parent from both sides. So far, so good. My main character is a woman with parents from either side, making her look angelic-human with yellow eyes, sharp teeth and a few other funny traits. She has lived as a guardian of the city for a long time, and she knows she will be living alone the rest of her life. Funny thing is she's fine with it. She say it's worth sacrificing one life to save many, even if that one life is her own, and the "life" she sacrifices is her social life. Heck, blowing up a building and killing a hundred people is worth it if it means she will save a thousand. And so for the question. What would the story be? I don't want the usual "save the world" crap. I'm thinking she can meet another one of those guardians (a hunter, actually. This one hunts down things from the other side my MC can't handle on her own. They are both women, so there won't be any romances. Probably.) Maybe it'll be inspired by Moby Dick, of all things. But I could really use some ideas.
