Imagine being on the losing side of the battles in The Lord of the Rings — Russian author, Kirill Yeskov did just that, and produced The Last Ringbearer. From an article about the book:
In Yeskov’s retelling, the wizard Gandalf is a war-monger intent on crushing the scientific and technological initiative of Mordor and its southern allies because science “destroys the harmony of the world and dries up the souls of men!” He’s in cahoots with the elves, who aim to become “masters of the world,” and turn Middle-earth into a “bad copy” of their magical homeland across the sea. Barad-dur, also known as the Dark Tower and Sauron’s citadel, is, by contrast, described as “that amazing city of alchemists and poets, mechanics and astronomers, philosophers and physicians, the heart of the only civilization in Middle-earth to bet on rational knowledge and bravely pitch its barely adolescent technology against ancient magic.”
