Magic and Science? It’s my dream come true! When it comes to magic there are two distinct teams. One team cheers for hard magic systems, such as what’s found in Brandon Sanderson’s books, where there are clear rules and limitations. The opposing team cheers for soft or undefined magic, such as what’s found in The Lord of the Rings, where there are no limitations and those who use it are shrouded in mystery. Which team will win? Easy – the team you like the best!
Today we welcome my favorite mad scientist author and board game enthusiast to the blog. Ryan Decaria is going to try to win points for Team Hard Magic in his article about magic systems and mad science. Cue the lightning! Muah ah ah!

The Magic System Mad Science Experiment
by Ryan Decaria
My mantra when writing science fiction and fantasy worlds is to treat magic like a science and to treat science like magic.
I’m gonna let that sink in for a minute.
Magic comes in two varieties: magic systems with rules and undefined magic. Brandon Sanderson is famous for the former in his Cosmere novels. Gandalf in the Lord of the Rings is a great example of the later. Who knows what powerful spell he’s going to come up with next. Still, in either methodology, magic can be seen as a part of that world’s natural laws.
Like any other natural force, magic can be studied, classified, and theorized about. The scientific method can be applied, because the cause and effects can be scrutinized. I’m going to say it again. Treat magic in your story as a science field of that world.
Now, your characters will probably not be scientist studying that magic (cept how cool is that), so they won’t necessarily care to use science or science terminology when wielding magic. I don’t think about gravity or how my internal combustion engine gets me to work. I just drive.
I came up with a great litmus test for your fantasy’s magic system. Let’s call it the Mad Scientist Experiment. For your magic system, imagine a mad scientist character living in your world who is trying to use the magic in new way by combining aspects or segments of your magic in unnatural ways. This can be the Frankenstein scientist, driven by the desire to create, the Doc Brown scientist, eccentric but good-hearted, or the nefarious scientist like Doctor Poison from Wonder Woman.
Does your magic have enough meat for them to operate? Can they create life? Can they seek immortality? What are the costs? What are their methods.
If you can’t answer any of these questions, perhaps you haven’t given your magic system enough depth. Answering these questions, might give your magic system a needed boost.
Here are some examples of great mad scientists in epic fantasy with mild spoilers:
- Saruman from Lord of the Rings
- Focused on industry at the expense of the natural world
- Breed a new species of orc
- Created great forges and explosives
- Became obsessed with power
- Ex-maester Qyburn of A Song of Ice and Fire
- Anatomical experimentation on still-living people.
- Excellent surgeon or a Torture Technician
- Created a Frankenstein-like creature
- The Lord Ruler in Mistborn (spoilers in this one get a little meatier)
- Found a way to gain immortality
- Created new races and the inquisitors
- Changed the natural laws of the planet
- Combined two kinds of magic to great effect
But what about science fiction?
There are two kinds of science fiction: One cares about how the science works and the other cares about how the science affects the world.
In the first, science knowledge is at a premium, and you better get it right. In the latter, the science just works and no one is questioning why. Take hyperspace in Star Wars or transporters in Star Trek. The more you dig into the science, the more preposterous they sound, so you don’t dig into the science. You avoid the science because it just works and your story is about what that technology does to society and to people.
You treat it like magic.
I love the term handwavium because it describes the science in terms of magic. Handwavium is what powers unrealistic or impossible technology, such as faster-than-light travel, teleportation, and artificial gravity.
In conclusion, to create a rich and deep magic system, imagine how a scientist would study the magic and how a mad scientist would exploit it. You might discover a few plot points and a couple of awesome characters along the way.
Remember my mantra:
When writing science fiction and fantasy worlds, treat magic like a science and science like magic.
