As is with many forums, i searched for anything relevant to what i was looking for or find the answers without posting this, but I've realised there isn't much that is similar. Also do excuse me for my probably poor English, it's very late (4:48am) and I'm rather tired. in my current WIP I am including magic, and it is based on the "five elements" which are fire, earth, water, earth and energy (such as sound or light). While i know this is a relatively cliché magic system and that many people seem to dislike it, i'll try to explain it before you make you're mind about it. So, first of all, any of the separate elements are not your typical "I can make fireballs" sort of magic if you could use it (i'll get to that later). First, you have to obey the simple law: energy cannot be simply created or removed, you can change, convert and perhaps even store it, but you can't just create it or delete it. Also, humans can't use it. and the only way they can use it is by controlling, in some form, an "elemental" (perhaps a better name is in order), which do not live in our world, but do interact with it. While capturing and/or controlling one is possible, it is definitely hard and not without it's risk. Also, each of the elements are at war with each other in their own little dimension and for the most part that those not affect the world, however, if let's say, water was defeated, it would result in tides no longer appearing or fish would die (all animals including humans are made of multitude elements with typically a primary element, for example, water for fish and wind for birds and the subsequent destruction would result in birds no longer able to fly or fish not longer able to swim or breath under water). This in turns ties into the cost of the magic, while energy cannot be created or removed, using magic in itself uses energy from that particular element, just like moving a sofa. Effectively, the particular element's magic you are using would be weakened (albeit not by a lot) because of you're effort to move the sofa, while this is typically not harmful, if one element is used extensively it could result in catastrophe. And even small changes in the element can be disastrous. Lastly, i should probably explain what the fifth "energy" element is, in this instance, you could illuminate a dark cave, or make a sound appear. however, this energy element is simply the energy in physics, you could add momentum to a ball rolling for instance. Energy is not life or death, it does however allow life to exist. So, my principal questions are: Does this make sense? and does it deviate from what results in this magic system being so hated? While magic users are principally non existent in the story, is it too underpowered? I feel like I have put a lot of constraints on this, but I suppose humans are not supposed to use this magic in any case. but then again, this magic principally serves to explain the elemental world which is in turn not a primary point of my plot. any other opinions or feedback are welcomed. My WIP is still in it's very early stages.
