The Plague Doctor's Growth

Cartyr Hellingon

The year was 1996, 2:34 AM. A new born child was gifted into this world. He grew up quite well. Cartyr's parents were actually quite amazed at their son. He was very intelligent, for example. Cartyr, at age 7. He was already doing work as freshman in high school would be doing. However, his parents went from amazed to scared, not for their child, but for themselves. When Cartyr turned 14, he created a machine that could change the molecules of someone's brain. This was a prototype, and yet... This prototype could do dangers to all around him. Cartyr, at lunch, at used it for the first time on senior student at the school who had a severe bipolar disorder.
The student was shocked into a coma, Cartyr was quite literally suspended almost immediately. The student was in a coma for 4 days before awakening. It had worked! His bipolar disorder was no more! Cartyr felt accomplished and yet... That was until a side effect occurred. Almost a week after he was cured, he suffered from sanity loss at exponential rates! Becoming severely insane by the next few days. For this, Cartyr was expelled from the school and had to be transferred to another.
It was trial and error, trial and error. Over and over again! No end to his miscalculations... At the age of 16, Cartyr met a very... peculiar doctor. His name was Dr. Eri Sylvie. A doctor that attempted to cure the plague, and yet... only age him immortality when he used himself as a test subject. This crazy doctor... Cartyr took big interest in. They shared ideas, and became quite close. That was until Cartyr became quite the friend with death. Eri wasn't... all right in the head. Actually, Eri suffered from various mental disorders, one of which made him snap and go into a rage all from the voices in his head. Some voices were cruel, mean, liars, and others were.. nice, truthful, and kinder ones. However, the cruel voices were more frequent and in times of anger. Eri snapped on a Cartyr when he was merely a young man.
Almost killing a friend, of which... Dr. Sylvie hadn't received a friend in a while. In a twist of amazement, Cartyr snapped Doctor Sylvie out of his state of rage. This created a bond that would strike a long term relationship. Cartyr went to college early, having no need to finish high school and received a job as a professional therapist. However, a patient of his became well known of Cartyr's intelligence, and heard of the rumors of the very machine that could fix mental disorders.
Cartyr, at first, denied the patients request on using it for his on disorders. However, he begged Cartyr for ages, until they finally struck a deal. He uses it, however... this patient may not tell anyone, NOT A SOUL nor may he blame the doctor for any side affects for this was his choice to use the machine. On the day of the test, Cartyr informed the patient that it would not be accurate, and that they had a deal. In the end, only 1 thing would be true. And it's not the fortunate one... The test did indeed fail, and Cartyr was thrown back, almost breaking his back as the machine quickly malfunctioned and broke.
The patient, in utter pain, attacked Cartyr, injuring him wildly as he soon blacked out. Waking up hours later, became a search for his patient. And then, the false part came along. Instead of keeping the deal, the patient instead went to the authorities.
It was both unfortunate as they court stripped him of his license and attempted to send him to prison for his unorthodox and dangerous experiments and tests. Cartyr may have been hit with a blast wave, and attacked by his patient. And now being sent to jail... But, something happened and unlocked inside of Cartyr. His voice, echoing, he merely says, "I'm not going to jail..."
And he sure as well wasn't, right in front of everyone's eyes, Cartyr had just... disappeared. Security tapes were placed everywhere, and when looking back at them. They had to slow them down at a low speed. Cartyr didn't just... disappear. He ran out of the building! But that would be impossible! Unless it wasn't... Cartyr, in some way, had enhanced speed. He ran out of their and practically destroyed all evidence to his name, before attempting to find Eri. Cartyr thought that Eri would know what to do...
Cartyr soon found Eri and he told him what was going on. Cartyr was panicked, stressed, and showed signs of grief, depression, among other things. All of this was happening when Cartyr was 22. He wasn't ready for any of it... Sooner or later, the authorities did find the two. Now marking Dr. Sylvie as a Target also. They both decided they needed a place to stay and so... they ran into the forest. Cartyr built quite the house for Eri, labeling it in Eri's name and they both began living there for the time being...
Cartyr's depression only further got worse as he slowly began to drink... A LOT. Cartyr began drinking in inhuman amounts of alcohol. Able to drink hundreds, almost thousands without getting wasted as well, hangovers only lasted a few minutes. Cartyr's depression May have gotten worse.
But, that wasn't the only thing... Cartyr has various other things wrong with him that he hasn't shared with anyone. Not even Eri, which is both troubling and dangerous. And even then, Cartyr built fake walls, and tunnels that lead throughout the house, some of which also lead to BELOW the basement. Where a secret room lays, a room where Cartyr continues to make and do his crazy, dangerous inventions, along with experiments. All in secret of everyone in the home... Not to Eri, not to anyone residents. Everything in that room is practically sound proof. And he tends to keep it like that. Refusing to tell anyone about his various problems with him mentally, Cartyr crafted a katana that actually enhances his speed to make him go even faster than he did originally. And yet... That is the only project he had shared with anyone in the house...
