The Gears of Eldoria
In Eldoria, a world powered by magic, seventeen-year-old Elian, the non-magical son of Duke Alaric Thorne, feels confined by his luxurious but isolated life. He's puzzled by the lingering use of swords in warfare despite advanced magic, unaware of the nation's hidden core problem: a slow, critical depletion of mana. Driven by fragmented memories of a previous life rooted in pure science, Elian secretly begins to develop a firearm and its explosive "gunpowder," to prove that even if he doesn't have magic, he could still survive, unbeknownst to him, this could shake the foundation of this world, change he core that people always hold dearly.
