I'm writing a fantasy story, and therefore I'm working on this magic system, but I'm not sure if its going to work or not. I have not yet worked out all the mechanics, but I'm not too worried about that. It's the very basics that are the problem. Here's how it works in a nut shell: to use magic, a mage would need an oculus, wich is a device he uses to keep contact between his body - witch is going to stay where it is, crosslegged in front of a fire - and his soul, witch is going to travel between the planets of our solar system. And here's why: all the energy a mage would need to do anything comes from the sun. But the sun is way to hot, way to powerfull, and WAY to dangerous to be used directly. But as this energy is radiated out into the solar system, it is also sorted out into different kinds. These are safe to use, but it does mean one needs to go to different planets if one needs to do different things. So as long as you know whitch planet to get it from, solar energy can be used to do just about anything: send a message, light a fire, kill a man, travel around, you get the picture. Now I don't mean to blow my own horn, but personally I like this, and I think it's pretty original too I'm only worried about using planets and all that in fantasy, especially ones that actually exist. If I start using planets and stars, I might also start using black holes and string theory. Not that I don't like that idea... but still some part of me feels it's out of place, like a lightsaber would be. After all, this is a world where most people still use horses to get around, and swords to kill one another so I think I'm worried about my fantasy story mutating into some fantasy-sifi mix that should not exist. can anyone help me with this?
