As we all know, magic is the result of drawing upon the timeless and eternal “God Time” to affect the material world of Time. And so sorcery as a magic system is a logical and materialist approach towards doing that.
But the sorcerous mindset is of the mundane, measurable, material world – as Nick Brooke correctly observed elsewhere, a “science”. Not all “sorcery” is expressed as magic spells, of course.
In the Second Age, the God Learners tried to understand the world through observation, analysis, and reason. One group of God Learners tried to duplicate the result of magic through material devices and machines. They settled in the area called God Forgot (which was part of the Middle Sea Empire) and founded the so called Machine City. They built war machines (including a giant harpoon firing crossbow now in Sun County), armoured self-propelled vehicles, and developed techniques of mass assembly of parts and even of magic weapons. This is all “sorcery” – or at least the product of the sorcerous “scientific” approach. Ultimately, they constructed their own “god machine”. But the gods found this intolerable and the Empire of the Wyrms Friends and the Old Way Traditionalists worked together to destroy the Machine City.
Leonardo is a local of God Forgot who has rediscovered some of this. Likely a genius in his own right, he’s built an Ornithopter, and various other devices. He’s likely already come up with the plans for countless others. If he could get enough financing and support, who knows what he could build – or even worse, what devices within the Machine Ruins he could restore to working order!
