So, after modifications, here it is, although I did this before going to sleep. If anything needs to be changed, or if something seems illogical, then I will fix it tomorrow.

Personality: Erion is a rather calm person that is able to think quickly when needed, but prefers to take his time. He dislike injustice, thinking that everyone should be treated as just as possible. He prefers to try to talk his way out of problems.

Bio: Erion was born a bit far from where Frisk lived. He actually lived up north for the first years of his life, his mother staying at home and his father working as a programmer. Life was a bit hectic in the first years, with his father having to switch companies a lot of times cause of problems and injustice in each companies system. Even if he was a hardworking man, lots of people did not like him, most cause of jealousy. Erion’s father had a very easy time figuring out problems, although it seemed that at each problem he fixed, someone created another, which made the company managers mad. This continued on for a couple of years, with Erion’s father going from job to job until he decided to start his own business, which made it easier afterwards, with people hiring him for multiple programs.
But while Erion’s father was having trouble, Erion’s childhood was going alright, with him going to school. Even though there were bullies, he was able to manage with them, not reacting to their threats and ignoring them. As time passed, Erion looked for a future job he could do. When he looked into science, he actually was intrigued to all the possibilities, like how reactors work and chemical reactions. So he started studying more to become a scientist, taking classes more related to math and how nature works. He continued his studies, but it was then that he had some difficulties.
You see, some of the teachers that Erion had thought about only themselves and the money they could do by teaching. This caused tensions between the students and the teachers. The worst one was Erion’s science teacher, a man named Frederick Gilberg… Not only was he boring in the class room, he asked the class to memorise multiple science equations and did not get any practice for the class. Erion always preferred to see things in action to understand them, and in a science class, it would be normal, but this did not happen. This was an affront to science itself! With this, Erion had a bad grade in the end of that class, only passing by 1 percent. 
This made Erion annoyed and mad. All year long people tried to contest against that teacher, but nothing was done, because of his status of being an ‘ancient’ in the school, having stayed there for a long time. Erion felt the injustice in this, especially because he had to work twice as hard then normal to learn other science equations.
Not only did this teacher cause him trouble, but he got into trouble with some of the gangs that existed in the school. You see, he actually helped a lot of students that were picked on by the gangs, telling them off and getting them to go elsewhere. It wasen’t long that Erion ended up in a fight with one of the leaders of the gangs, but what happen next was surprising. Erion moved quickly, grabbed the guys fist, before quickly pulling at the guys arm and then throwing him over his back onto the ground. Just then others tried to jump on him, getting him punched a bit before a teacher came and then stopped them. Lucky for Erion, they got him to the nursery and the hospital quickly, with him only ending up with a scar of a sharp object on the left side of his face.
It was at that time that his dad, who had gathered enough money, decided to move down south with the family, going to get more work and actually work with a big company down south. With that, he bought a new home and transferred everything from out north to down south. Erion had to fallow with his mom. He was sad to leave his friends behind, but he knew he could still keep contact with them online. Still it was hard for him in the first days.
So time passed, with Erion starting at a new school that had better teachers and had very interesting people, especially one man that did gym classes, and did fencing classes afterwards. Because of this, Erion felt like maybe fencing would be a good choice, and that learning about it would make him more agile if he ended in combat like back there. So he took the courses. Week after week he would go to the class, learn new techniques and master it more. In the side time he would take classes of first aid and continue his studies. At later in the day, he usually ended up going outside, going on a ledge of Mt. Ebott, looking up to the sky, relaxing. 
It was after that he then heard the news about monsters coming out of underground. He was surprised by this, and worried. But he though nothing about it. He then went to his usual spot, before then hearing a noise. It was then that he met with David. After telling him that he meant no harm, they then looked at the sun together and talked. What kinda intrigued him was how monsters actually existed, with magic and everything. Lot of scientists would think of magic as disgusting and an affront to so called nature… but for Erion, it was actually a new door to a different kind of world. Him and David became friends soon afterwards. Life then continued on, with Erion going to college, still following his child hood dream of becoming a scientist, but feeling also that maybe… Maybe he could do more. Sure he loved science, but something made him think. Seeing how there were tentions between monsters and humans, and how his new friend was rather a joke in the school, he was thinking a bit more on all this. He started to take other kinds of classes, a bit more philosophical and seeing other ways to talk to people and all.

It was then that he heard about the human that brought the monster had disappeared. A boy named Frisk…  He heard what David said, and about the fears of a possible war between humans and monsters, and Erion was worried. If that were to happen… he just didn’t know.

Appearance: 
Erion usually wears a leather jacket of a black coloring with blue cargo pants. He has slightly long brown hair, and his eyes are of a blue coloring. He is rather medium size, although he has a small scar in the right side of his face.

Junior jumble for the win!

P.S. Erion is secretly an anime fan :P
