Designing a magic system: nine questions every fantasy world should answer

Magic is quick to describe in fantasy and hard to do well. In a German-language post on worldbuilding, the author Joshua Martel explains how he built the magic system of his world, Ananthara, and I found the list of questions behind it extremely useful. The core idea is that magic must not only deliver spectacular powers. It has to shape culture, religion and history.

First comes the source. Where does the power come from: faith, blood, knowledge, emotion, the soul? The answer shapes politics, conflict and identity. In his system, Thal'Ithara, it is the soul, so magic grows out of memory and emotion. Then there needs to be a recognizable pattern, such as elements, words or rituals, so readers can follow the rules.

I especially liked the section on limits, taboos and costs. Someone who can only teleport to places they already know, or who sees only possible futures that they must interpret, automatically becomes a more interesting character. Mastery does not have to mean raw strength; it can mean restraint.

Then there is the question of how cultures deal with magic. In one region it is suppressed because of a historical trauma, in another it is understood as part of a natural cycle, and in a third it is studied and used for healing. Add to that a distinct sensory visual language, a test for whether villains, states or markets abuse it, and a look at the Untouched, whose magic never awakens.

The final test is simple and hits the mark: what would change if magic did not exist? If the answer is "hardly anything", it is probably just decoration. I like to use this question as a touchstone for my own projects.
