How to Create a Unique Magic System: An Author Explains

One of the most important elements of writing fantasy has to be the idea and concept of the magic system. Magic gives your world flavor, tension, and wonder and it allows for it to truly feel unique. One of the biggest things that separates fantasy from reality is the presence of a full-fleshed out magic system. However, building a magic system that feels fresh, unique, and logical to your story’s world is harder than it might seem at first. The good news is that creating a unique magic system isn’t just about memorizing someone else’s rules: It’s about combining simple foundations with creative twists and fitting these in logically with your world’s rules and conventions. In this post, I’ll walk you through the key steps of building a magic system and help you come up with some ideas with creative prompts and examples. 

Before We Get Started…

It’s important to note that every writer will have their own way of implementing and developing a magic system. It’s also important to note that just because one writer likes to codify strict rules, that doesn’t mean that you also need to codify strict rules. However, you need to be aware that logic with your world building is essential to writing a successful magic system. 

I like to think of magic systems like scientific systems in the real world (i.e., physics). We understand that there are rules that the world follows due to the systems of physics and similar concepts. The same is true for a fantasy world, but magic allows you to have more room for wonder, surprise, and the “supernatural.” You don’t need to make it realistic to our world, but you need to make it realistic for your world.

How to Create a Unique Magic System for Your World

Step 1: Hard or Soft?

The first thing you need to consider when it comes to creating a magic system is whether or not your system is hard magic or soft magic. What’s the difference? It’s actually really simple: 

• Hard Magic: Strict rules and guidelines
• Soft Magic: Loose rules, more mystique around it

If you find that you’re the type of writer that likes to come up with an explanation for literally everything in your world, then hard magic is probably what you want. 

If you find that you prefer less rule-setting and more exploration and intrigue, then soft magic is probably a good idea. 

Step 2: Choose Your Power Source

Every magic system needs to have a sort of fuel behind it. You need to think about firstly where yours comes from and then how this source will shape everything that comes next. You want to think about who can use the magic system, how it changes societies, what costs are associated with it, etc… 

For example, let’s say you have a magic system that draws its power from dreams, but only nightmares are strong enough to work. We’ve already created a source and a potential limitation.

To draw on my own works, in my series, The Fallen Age Saga, the magic system of the Ones Above actually comes from their own “spirits” or auras as they call them. Each member of this alien species has a different frequency that defines what they’re better at magically-speaking. Some of them use fire-based magic, others use blood-based magic, and some even use metal-based magic and can turn their arms into swords.

Every magic system needs fuel. Where does yours come from? The power source will shape everything else: who can use magic, how it changes societies, and what costs are associated with it.

Prompt Ideas:

1. Magic is fueled by broken promises and the stronger the betrayal, the stronger the spell.
2. Magic is stored in bloodlines, but each generation dilutes its strength.
3. Spellcasting requires offerings of sound
4. Magic flows through rivers and a corporation seeks to drain the rivers and store the water in its own systems

Step 3: Define Rules and Costs

Without boundaries, magic becomes an unstoppable juggernaut force in your story that will throw the balance of everything else off. The best systems have rules that are logically grounded in the world and can help create drama or fuel conflict. The rules help readers understand what is possible and what isn’t. 

Consider physics on Earth: We can’t just jump and keep flying out to space because of the pull of the gravitational force on us. Gravity comes from the core of the Earth. Earth was designed to keep its inhabitants grounded up to a certain extent, which is intelligently designed. Other planets that don’t sustain human life do not experience this level of a gravitational pull or they may experience a significantly higher gravitational pull. 

Think about how you can apply that exact same idea to your own magic system!

Questions to consider:

• What can magic do?
• What can’t it do?
• What’s the cost?

Prompt Ideas:

1. Every spell requires a sacrifice
2. Magic drains emotions
3. Magic always backfires slightly from a physical sense
4. Each spell consumes a physical object and that object vanishes permanently
5. Magic requires written contracts; each spell must be signed in blood.

Step 4: Weave Magic Into Society

Magic systems in fantasy stories (or sci-fi or any speculative fiction subgenre) don’t just exist in a vacuum. They will inevitably shape society in one way or another. It can shape religion, politics, culture, everyday life, technology, warfare, etc… 

For instance, do some people believe that magic fuels inequality? Do others believe that magic should be controlled? Do some believe that magic should be left to run wild?

A good test of any system is asking yourself: How would society change if I removed the magic system from it?

Drawing from my series, in The Fallen Age Saga, magic is literally the backbone of the society of the Ones Above. All citizens are trained in magic, all are soldiers, and all technology is fueled primarily by magic and secondarily by pure technological rules. For example, their guns use bullets, but the guns are primarily ways to channel raw magic and weaponize it. This affects war and their society. 

Questions to ask:

• Who controls magic?
• How do people view magic?
• Does it create inequality or new hierarchies?

Examples:

• In Avatar: The Last Airbender, bending defines nations and warfare.
• In The Legend of Korra, a conflict sprouts out over questions of inequality for people who cannot bend elements

Step 5: Add a Unique Twist

You want to think about adding your own unique twist to any magic system. You can certainly use elemental magic, there’s no problem there, but you need to think beyond just elemental magic. We’ve already seen elemental magic many times before, so how can you actually make it intriguing and interesting for your own purposes?

In The Fallen Age Saga, some of them can literally channel nuclear energy for magic. They can survive extremely high levels of radiation. Some of them are so good at Nuclear Mage Arts (that’s the subclass system), that they can fuel an entire world-destroying spaceship that runs on their own nuclear energy.
