Tips on Borrowing from Actual Scientific Concepts to Enhance the Magic in Your Setting
Fantasy world-building often feels like the realm of the wildly imaginative—floating islands, time-stopping spells, and magical beasts that defy every law of nature. But what if your fantasy world could be even more immersive, logical, and magical by weaving real-world science into the mix?
Borrowing from biology, physics, chemistry, astronomy, and even psychology can enrich your setting, making your magic feel like a natural extension of reality rather than a break from it. Below, you’ll find detailed tips and examples for blending real-world science into your fantasy setting without turning your novel into a textbook.
🌍 Why Use Science in Fantasy?
- Incorporating science into fantasy helps you:
- Make your world feel believable and internally consistent
- Surprise readers with systems that make sense, even when magical
- Ground the extraordinary in the familiar and the possible
- Build richer, more dynamic magic systems
- Fuel creativity with real phenomena stranger than fiction
🔬 1. Base Your Magic System on Scientific Principles
Many of the best fantasy systems feel magical, yet operate with rules—much like physics. In my world of Aztharian, certain kinds of magic come through the use of antimatter. Since the matter in the world isn’t the same as it is in our world, using antimatter doesn’t cause an explosion. However, if a magician from Aztharian tried to use magic in our world, it would result in an explosion.
Real-World Inspiration Examples:
Thermodynamics: What if mages could only create heat by draining it from nearby matter (causing frostbite while summoning fire)?
Conservation of Mass: A transmutation spell might require breaking an object down into atomic particles before reassembling it.
Entropy: High-level spells could accelerate entropy, causing rapid decay or entropy-reversal to heal wounds.
Tip:
Choose one scientific law and let it limit or shape your magic. Limitations make magic more interesting and strategic.
🧬 2. Use Biology to Design Magical Creatures and Ecosystems
Nature is already magical. You don’t need to reinvent everything—just give it a twist. In Aztharian, certain people can talk with the trees, usually people who are at an underdog position in life.
Real-World Inspiration Examples:
Bioluminescence: Glowing mushrooms or animals evolved in dark, magic-soaked forests.
Symbiosis: Magical animals could bond with wizards to channel spells more efficiently, like lichens exchanging nutrients.
Camouflage & Mimicry: A forest creature might shapeshift not by magic, but by adaptive chromatophores, like a cuttlefish.
Tip:
Use real adaptations and give them magical enhancements. The more biologically grounded your beast, the more it will feel alive.
⚛️ 3. Blend Alchemy with Chemistry
Alchemy is a staple of fantasy, but instead of vague potions and mysticism, make it tangible by borrowing from chemical principles.
Real-World Inspiration Examples:
Catalysts: Magical ingredients that only activate in the presence of certain emotional energies (fear, joy, grief).
Reagents: Potions that change when exposed to magical metals, much like how sodium reacts explosively with water.
Titration Rituals: A precise, scientific magical process requiring drop-by-drop ingredient control.
Tip:
The more precise your magical alchemy is, the more opportunities for failure, discovery, and tension in your world.
🌌 4. Build Cosmic Lore from Astronomy and Astrophysics
Instead of just “three moons and a red sun,” let astronomy help you create a magical cosmos. In the world of Aztharian, there are constellations that can be used for magic. However, they are not made by stars but by a different type of matter and they were specifically created for magic use.
Real-World Inspiration Examples:
Gravity Wells: Certain places in the world might warp time because they sit on magical gravity distortions.
Tidal Forces: Magic waxes and wanes based on lunar alignment or stellar cycles.
Planetary Orbits: Ancient prophecies might be triggered by rare alignments that actually follow realistic orbital mechanics.
Tip:
Use real celestial mechanics to give your prophecies and omens weight. A magical eclipse is way more impactful when it happens once every 400 years because of how your solar system works.
🧠 5. Infuse Magic with Psychology and Neuroscience
Magic doesn’t just change the outside world—it can also twist perception, memory, and emotion.
Real-World Inspiration Examples:
Neuroplasticity: Spellcasters can rewire their brains over time to better handle magic—or go insane.
Mirror Neurons: Enchantment magic could work by mimicking brain patterns between two people.
Lucid Dreaming: Dream mages might enter the astral plane only when in REM sleep, with real psychological risks.
Tip:
Tie mind magic to real cognition and psychology, and your magical illusions, telepathy, and dreams will feel eerily possible.
🧭 6. Geography, Geology, and Magical Landscapes
Why are all magical forests just… glowing trees?
Real-World Inspiration Examples:
Plate tectonics: Your world’s fault lines might leak magical energy—like ley lines—because of pressure and crystal deposits.
Volcanic soil: Magic-rich farmland thrives in volcanic regions where the ground absorbs centuries of ash and death.
Weathering: Magical ruins could change over time based on real geological processes, giving you built-in history.
Tip:
Study earth science to shape your geography. Fantasy worlds feel more real when mountains, rivers, and deserts obey natural formation rules—with a few mystical exceptions.
🔁 7. Use Evolution and Ecology to Create Magical History
How did life evolve in a world where magic exists? In Aztharian, magic was part of the creation that the Creatrix endued the world with.
Here
Real-World Inspiration Examples:
- Creatures evolve magical traits to survive arcane predators.
- Sentient races develop rituals that mimic natural predator responses.
- Entire regions adapt to fluxes in magical energy, like species in floodplains or deserts.
Tip:
Let evolution tell a story. If magic shaped life, it should have affected food chains, intelligence, and symbiotic relationships.
📚 Bonus: Science-Based Magic System Ideas
Here are some one-liner ideas for you to develop:
Chronochemistry – Magic that alters chemical reactions over time, allowing for delayed spells.
Photospellcraft – Sunlight-based magic dependent on the color spectrum.
Magnetoarcana – Spells that function through polarity and magnetic force, pulled from planetary cores.
Neuroalchemy – Emotion-linked alchemy requiring hormone extractions or brainwave stimulation.
Genethaumaturgy – DNA-based magic; spells are written into the genetic code of living beings.
🌠 Conclusion: Magic Is Just Science We Don’t Understand (Yet)
By borrowing from real-world science, you can enhance the believability, wonder, and complexity of your fantasy world. Magic doesn’t need to contradict science—it can evolve alongside it.
So whether your world has spell-runes powered by quantum theory or glowing fungi that teleport spores through alternate dimensions, use science as a springboard—not a cage.
Let the known fuel the unknown—and watch your world come to life in new, unexpected ways.
