Nathan was born in the city of Digginspoint, located in the Zarindan province. His mother, Inari Yttria, was a skilled elementalist and swordswoman who would usually incorporate element bending techniques and classic swordplay, thus making her a force to be reckoned with. She was dubbed "The Thorned Rose", and she had earned her position as Knight Captain through hard work. Nathan was pressured to carry her legacy on. His father, Rudolph McDonald, was a wizard of sorts. He was a weird one. He would write in some ancient language and mutter incomprehensible wordings that he called "spells". Johnny was, as said earlier, pressured to carry on his mother's legacy, and this caused him to become somewhat introverted and hardy.

Nathan's mother forced Nathan to learn how to manipulate all the classical elements, as in all of them. However, Nathan was more interested in guns. He had his mom buy him a toy dart gun, and he would shoot his neighbors living in the nearby household through the windows with it, thus showcasing his excellent aim and lack of proper discipline. The unfortunate neighbors did not dare complain, for they were afraid of the brat's mother, so the best they could do was close the windows. Nathan would get spanked for doing so, nonetheless. Nathan also showed an interest in his father's spells, much to the father's surprise. He learned to write in ancient glyphs, and he began tinkering with magic runes at a young age. His mother was very disappointed, but was rather sympathetic towards her son since he was an only child. Nathan ended up only learning how to manipulate plasma, which wasn't a classical element to begin with. He learned it well anyway, and would usually be seen trying to create elaborate shapes out of the plasma instead of hurling it like he would in a fight. His mother was even more disappointed, but his father pointed out that their son had to learn how to put focus and effort into element bending, so the mother decided to watch in all her disappointment.

Soon, Nathan had become an independent teen. His mother had become very disappointed in him, since he hadn't become a master of the element like she had become at his age. Nathan initially refrained from joining the Tower of Stars. He was growing up when futuristic weaponry was becoming the norm, so he came up with an outrageous idea: using guns to cast spells!

Yes, he came up with that. He's still somewhat proud of it.

He studied weaponry and magic at the same time. He conceptualized fitting runes that could cast all kinds of magic spells into guns. After a lot of sketching and building, he had designed his twin pistols: Order and Chaos. He also trained in stealth, like most gun-wielding military trainees at the academy would. He dug deeper into his father's books and saw all sorts of spells and illusory tricks. Eventually, he would learn how to use these in fast-paced battles.

Eventually, Nathan ended up popularizing the usage of magic runes once again. His innovation caught the eyes of the Tower of Stars, and they offered him a position as Artisan. Nathan accepted it, and he got stationed in his hometown, Digginsworth. He is generally affiliated with the Tower of Steel, and he sometimes crafts weapons for his division.

On a regular workday, Nathan sits in his office in the daytime, usually with nothing to do. At night, he patrols the slightly busy streets of Digginsworth, and sometimes in nearby cities. He works full-shift, and he only gets breaks on Saturdays. He does subdue criminals sometimes.
