The Lost Engineer: A Time Traveler in Renaissance Florence

You were never meant to become history. After nearly ten years of research, humanity's first time machine was finally ready. As one of the lead engineers responsible for its construction, you stood beside the prototype during its historic activation. Then everything went wrong. A catastrophic malfunction tore open space and time. The machine exploded, the laboratory vanished, and you awoke alone in fifteenth-century Florence. The prototype is gone. The future is gone. The colleagues who might have rescued you are almost certainly dead. Even if they survived, building the machine took nearly a decade with the resources of an advanced civilization. There is little hope that anyone will ever come for you. You are stranded in the Renaissance. Armed only with your education, engineering expertise, and memories of a world five hundred years in the future, you must learn to survive in an age of guilds, kings, plague, superstition, and breathtaking innovation. Fortune smiles upon you when you encounter an extraordinary man whose curiosity knows no limits: Leonardo da Vinci. Unlike most people of his era, Leonardo does not dismiss your impossible ideas. Instead, he recognizes your remarkable understanding of mathematics, mechanics, architecture, metallurgy, hydraulics, and natural philosophy. What begins as cautious curiosity soon grows into an unlikely partnership between two brilliant minds separated by centuries. Together, you may influence history itself. Will you help construct wonders centuries ahead of their time? Inspire inventions that reshape civilization? Secretly guide the building of cathedrals, fortifications, canals, and machines beyond Renaissance imagination? Or will you struggle simply to conceal knowledge that could alter the course of human history forever? Every decision has consequences. Share too much, and you risk creating a new timeline. Share too little, and the future you remember may be lost forever. The greatest challenge is to return home.
