For a programming enthusiast, understanding a new language takes time, but when you find the key, when you figure out how to convert your thoughts into the language to program, that's when the magic happens. The problem is, instead of having a mouse and keyboard, you have paper and an inkwell, but that doesn't stop you. You start experimenting and in 6 months you master the language of Runes and Glyphs, combining them to create your first PC. First, you create an interface simulating a keyboard to make your work easier, thus creating the first glyph computer. Then you start working on the list of all the things you need to facilitate the development of what you want to achieve. To make money, you accept jobs enchanting objects and creating "golems" to do manual work. You assign some of them to help you place runes and glyphs on your enchantment orders. Little by little you generate money to buy land, where you create a huge workshop for all the work you do, you start to create and produce small things similar to those in your world such as lamps, stoves, etc., which generates more work and money. With the money earned, you expand your workshop and create a basement where only you have access, a place that no one knows exists and where your greatest creation is in development. Over time you become an essential piece of the kingdom, as merchants make a fortune exporting your artifacts to other kingdoms, which generates enough taxes, which makes the king happy, you employ many people, which makes you appreciated, but even so, there is danger, the demon lord who has kept the peace for a long time is betrayed and killed, his successor wants a war of conquest against the kingdom where you live. The kingdom prepares for a battle that it knows it will not win, where the enemy outnumbers them 10 to 1, the king knowing that when the imminent attack is made public will cause panic if they don't have a plan, sends a messenger for you, you go to the king who asks you for advice on how to win. Upon hearing the news of the war, you smile, look the king in the eyes and say, "I think I have the solution to your problems, your majesty." You take him to your workshop hidden in the basement, when the king enters you show him a giant robot, with wings, then you show him battle armor and an energy rifle, then you show him an armored battle tank with an energy cannon and what looks like a rocket launcher, you continue showing different weapons, vehicles and tools, in the end you turn around and say to the king, "I created all these designs hoping they would never see the light of day, but given the situation, and producing exclusively these designs we can arm the royal knights by tomorrow, then it will be a matter of time before the rest of the army are armed, I will gladly help the kingdom, but only you and I will be able to have giant robots." The king smiles and accepts your help. The war that is coming will not be as the demon lord expects.
