How on earth can you explain magic (I know, I know, you don't need to)?
Is it a power hidden within us (chakra and that kind of stuff)?
How on earth can you destroy a house just by shouting Simsalabim?
Do you ever care to explain to your readers how it all works? Why only elves can use it or why everyone can use it except for elves (hope you get the point).
And if you explain magic as your hidden power that is just waiting to be released, how can you explain that your hidden power is taking the form of ice, wind or teleportation?
Do you ever care to explain or think about these things? No? Yes? Is it a bad thing to care?
