i'm gonna be talking about this universe. source.

1. How is it learned and executed?

They are born with it, but they, of course, don't know how to use it properly, so it is teached in their school with a similar training to militarity. It is also fair to mention that it's not considered magic, but abilities. The one that is called magic is banned and people with this power is killed.

2. How is it accessed?

Again, they are born with it. Humans weren't able to have these powers before, but through gene editing it was possible. (Don't ask me how that makes sense, it's fantasy).

3. Does it have a will of its own?

No.

4. Is it restricted in space and time?

Some are, such as the elemental, since you obviously can't do water-control on a desert, for example. But neither are restricted for time.

5. What does available magic do?

Most things, there are telekinesis, strenght (which makes you into sorta into Colossus), elements-control (because I wante dto rip-off Avatar), and magic. Pretty sure I'm missing some.

6. How does it relate to the character, plot and theme of the book?

Well, the gene editing program was created to fight in war, a war that has been distroying the humanity (and planet) for almost 2 centuries, a war promoted by tyrants. After a long while the gene simply became part of the humans, and prophecies were born, that one day 3 magicians would end with the suffering, but seeing as most of them are dead, seems unlikely. The characters, are 2 powerful rich ones, from which one tries to have a normal life since she feels shame for living in that way; and the other two, are poor and live what's normal. Though the youngest has magic powers, and a fire in the house of the powerful ones kills all their family; they go in the run, someone is trying to kill them, and they have to protect the youngest, not because of the prophecy, but just becasue her life is worth living!

7. What is the cost of magic?

Well, dead for some.

8. What can it not do?

It depends on which type you got, but for the most powerful ones (magicians), it imitates all powers but for a limited time, and it's own power isn't the most powerful of them all (magic is basically a copy-cat).

9. How long does it last?

Magicians can make it last depending on their training knowledge, elements can make it last as lon as the elements last and/or are destroyed (ie. a wall of rock won't simply fall down unless it's taken down), and the rest simply get tired at certain point, or injuried, but last the double of magic or more. There aren't set times, but averages.

10. Who can use it?

Anyone born with it.

11. How do others react to it?

Magic = bad, anything elsee = power or soldiers.

12. Why haven’t people with this power taken over the world?

They have, it's believed that the leaders are some sort of hybrid magicians that don't have the full power of one, or aren't really one.
