The witcher: Industrial era (Concept story)

Long ago, world was plagued by supernatural, chaos, superstitions, diseases and so on, the mages manipulate people, the kings lived like tyrants, the priests misguide others, the superstitions cloud judgement of people, the plague took many lives and thus, the entire world was in dark era. Until one day, a hero rose who refuse such kind of world, his name is Robin aka Robin the lawbringer, he is a natural born witcher, born from Geralt of Rivia and sorceress Yeneffer, a existance that was not supposed to be possible as witchers are made not born, not to mention both parents were sterile former due to mutation and latter due to strong source. Nevertheless, such existance is born, Robin is similar to regular witcher except his cat eyes were blue instead of amber, perhaps a result of him being natural born. Robin ace as monster hunter and alchemist, though his true passion lies his scholary pursuits. Although Robin is one of the greatest alchemist, aside from being a witcher, he also pioneered a new knowledge, technology. He wrote many books on moderm physics, modern mathematics, modern biology and modern chemistry. Since, these knowledge only require the understanding of natural laws and using those laws into something useful, it can be practiced by anyone, Robin created many things that inspired other to learn it as well, armed with modern knowledge, the literate amongst the common folks solved many problems through non-magical means. Soon, famine disappeared with creation of manures and fertilisers, firearms are crafted to kill monsters, the modern medicines are brewed which while not have immediate effect like medical potions, can cure any illness, including catriona plague, electric torches are crafted replacing traditional fire torches, electronic are crafted replacing artifacts, making everyone's life easier, various machines are built doing may people's work, the various power generators like steam engines and dams are built to replace source, and many other things happened thanks to knowledge provided by Robin the lawbringer who is revered as first technologist. Thus, the dark ages ends, and the industrial era begins, with technologist replacing mages as new sorcerers of this new era, with scientists, engineers, mechanics and doctors shaping the world through non-magical means. Thus, a new society is built where merit is prioritized over lineage. Eventually logic dismantles superstitions and old religions, as tecnology become both the new reality and religion. As for the nations, the old monarchul is replaced by constitutional monarchy, while kings still exists, they are purely ceremonial, as true power held by elected governments. Thus, the world moved away from darkness of past, but even in this new era, the new problems will always follows.
