The Scientific Method is immensely helpful, but so is literal magic. Would the power of science prove to be more powerful than the power of wizardry? It’s tough to say, but author Cameron Johnston certainly speculates on the idea in the Big Idea for his newest novel, First Mage on the Moon. Read on to see how the Space Race might’ve happened with the help of a wizard’s staff.
CAMERON JOHNSTON:
For a bunch of wise folk that meddle with reality and break the rules of standard physics on a regular basis, wizards and mages in fantasy media seem a remarkably uncurious lot. Sometimes magic users are far more interested in other dimensions and eldritch creatures than in the mortal world they themselves inhabit. How many of them look up at the stars and wonder what they are, or gaze at the moon and ponder what that shining silver disc really is…and how they might get there?
First Mage On The Moon was born from a single Big Idea (OK, OK…the idle thought of a fantasy-fan): Without science, how would wizards describe gravity? Inevitably, that grew arms and legs and tentacles and thingamabobs into: What would they make of outer space? How would they breathe in a spacecraft when they don’t even know what oxygen is or why air ‘goes bad’. What about aerodynamics? and a whole host of other questions I didn’t then have answers for. When you only have a magical understanding of the world and the closest thing to science is the semi-mystical and secretive practice of alchemy, well, then things get complicated if you want to build something to visit the moon. Magic is not going to solve everything if you fly straight up and try to hit a moving object like the moon, and don’t factor in the calculations for orbits, gravity… or indeed the speed/friction of re-entry.
Science is an amazing and collaborative process and Earth’s 20th-century Space Race was a species-defining moment, but what if that happened in a fantasy world of mages, golems, vat-grown killing machines and grinding warfare. What if a group of downtrodden mages sick of building weapons of mass destruction for their oligarch overlords decided to go rogue and divert war materials into building a vessel to go to the moon, the home of their gods, and ask for divine intervention in stopping the war. When you have no culture of shared science, where do you even begin?
All those thoughts and ideas stewed away in the back of my brain while I was writing my previous novel, The Last Shield. As all authors know, there comes a stage of writing a book when your brain goes “Ooh, look at the shiny new thing!” Very helpful, brain, coming up with magical rocket ships when I’m trying to write a book set in a fantasy version of the Scottish Bronze Age – thanks very much! That idea of wizard-science and magical engineering lodged there, immovable, and my next book just had to become First Mage On The Moon. Which was handy, as I was contracted to write another standalone novel.
While the US/USSR Space Race and modern science of our very own Earth was inevitably a huge influence on my novel, so too were the theories and writing of its ancient thinkers. Around 500 BCE, Pythagoras proposed a spherical world, and Aristotle later wrote several arguments for the same theory, such as ships sailing over the horizon disappearing hull-first and different constellations being visible at different latitudes (all of which may have given the Phoenician sailors and navigators certain thoughts too). And then comes Eratosthenes, Chief Librarian of Alexandria, and a very smart dude who was able to calculate the circumference of Earth by using two sticks in two locations and comparing the angles of their shadows. If those ancient Earth scholars could calculate such things, then surely fantasy mages, with all the magic at their disposal, could do more than fling fireballs at each other. There had to be some among them with the desire to explore beyond the bounds of myth and magic, gods and monsters, and given the opportunity to work with like-minds to build something that has never been done before, they would surely take it…despite the risks.
Found family, magical engineering, and mad ideas of actual science in a magical world all came together to form First Mage On The Moon. As much as I love my morally grey characters in realms of swords and sorcery, it was deeply satisfying to write something that little bit different, a hopeful story about human ingenuity in an increasingly fraught world.
