He was an oddity amongst his family, they may have been a noble family where he was from but he was nothing like them. His mother despaired but his father encouraged his behaviour. Born with bright green eyes and soot black hair they knew he was different, the black sheep of the family, more interested in the science and engineering rather than social meetings and looking good. He had a skill to see things and little details that others couldn't, a different view of reality and tended to hide behind a mask of cold indifference when in reality he was an easy going guy.
At five years he demonstrated an interest in taking apart the old clocks. At eleven he made his first clockwork model, less than a year later he started studying crime scenes. At fifteen he enrolled in an apprenticeship for engineering. At sixteen... everything changed.

"Momma?" He called as he stepped up cautiously, clutching multiple papers containing drawings and schematics, his footsteps echoing across the silent corridor that made up part of his home. No answer. 'Perhaps she'd fallen asleep again?' He thought to himself as he stepped up to the living room door, he opened it and stepped inside. It was pitch black inside, the curtains were shit and the lights were off. Feeling cautious he walked forward until he stepped in something, looking down he discovered under the light of the corridor outside that it was a copper smelling red liquid.

Blood.

As he kept looking the true horror was revealed to him in the form of both his parents, slaughtered in the most gruesome way possible. His mind went into shock, unable to process the gore in front of him, snapping back to what he'd learned in his biology lessons. As if on autopilot he started checking the bodies making mental notes and deductions about everything in the scene: Fresh kill, made with a blunt instrument, left a trail of blood from one body to the next... That detail stood out to him.

He caught the killer in less than an hour, bringing him down with his rope dart he'd picked up while in a Chinese settlement, then brought him to the police. The funeral was held a few weeks later, he felt nothing but a cold resolution, no one offered him condolences for fear of invoking his wrath and grief. He spent weeks in therapy but nothing could replace the emptiness he felt until he started noticing things the police has missed. He had a new purpose now but he couldn't let the enemy know who he was.

While scouring the world for teachers he discovered he had abilities that rivalled those of Alchemists and Religious figures. He could make substance from light, shaping it to his whim and forging weapons and armour from this hard light. He could also channel the element of lightning, from a small shock to a raging storm. He could clone himself using the light he made, fly using wings, communicate through thought and push himself a lot longer and faster than any other person. He trained himself in his abilities for months, naming his attacks and discovering his true self. Then he managed to go past the limit and unlocked a different form for himself. With this new version of himself came a new name and a new purpose.

Binary Blitz, the Honourful detective blessed with powers of the supernatural.

At eighteen he was at the height of his prime, he'd perfected his set of skills over the two years he had. Using the family fortune to fund his lessons and giving up the luxury he had in order to begin a crusade against those who sought to harm others for pleasure. He'd also gained quite the reputation in the little network of killers; he was the Murderers murderer, bane of thieves and the terror of slavers. His work inspired others to try help but he knew that to be the best you had to hide in plain sight, needless to say if a bad guy heard a voice intone "Fourth Wall" they knew they were done for.

He had his dream job, an engineer of all things, and used this job to find a case. If he did he sacrificed a sleepless night to solve it, if he didn't he could finally get some rest knowing another life was spared. He rose through the ranks of his job by day and built his reputation by night, learning new things from his job that he could use during his work.

For eight years did he fight, until a trap did render him incapable. He knew by then it was time to retire, to let others take his mantle. He threw himself into his job and maintained a tranquil peace for three years.

Little did he know, that this peace would soon be shattered. By another child who suffered differently to he.

--------------------------------------------

The other, however, was born a prince to a thriving kingdom of peace and virtue. He was also different but only slightly as he had brown and white ringed eyes, also he always felt empty for some reason. Ever since he could remember he'd felt some piece of him was missing and the other half was aching to be free. Why did he feel this way? It wasn't until "The Accident" that this question was answered, rather violently.

It was well known his cousin was a cultist, always preaching about saving their souls or something ridiculous. The cult he lead grew more and more violent over the years he grew up, convinced he was some sort of saviour reborn because of his oddly coloured eyes and tried multiple times to take him from his parents only to fail. One day they caught him unawares while he was playing outside and took him to some sort of ritual room, they tortured him endlessly and no one heard his cries. Until something within him broke free, he "woke up" hours later to find them all slaughtered and he was covered in blood. By then did the police rush in and he blacked out properly only to awaken in hospital with his worried parents watching him.

The incidents started a week after he'd gotten out the hospital, he'd started to have blackouts when he was walking around minding his own business then waking up much later clutching a knife and covered in blood. Later it would be reported that someone was dead. Scared he hid his blackouts from his family and started trying to find a cure for his condition, contacting multiple priests and alchemists to find a cure. All failed, all killed afterwards. As if the things that resided within him refused to go quietly.

For fifteen years did he look until he was crowned king, it was then that he finally figured out what was plaguing him. Some sort of inner demon, the dark side of his psyche. He killed without remorse or feeling and was never selective with his targets; men, women, children. All dead by his hand. He had numerous powers, from minimal time control to magical sigils which he'd summon knives and tendrils of shadow from. Superhuman in every way; strength, speed, stamina, durability and senses. It made his other self the perfect killer. The apex predator in a kingdom where there was no war or crime. They weren't prepared for this. No one was.

His efforts to contain the beast within led to the other being in a foul mood when he managed to break free from the chains that kept him locked within the darkest corners of his mind. A mind they now shared whether they wanted it or not.

Finally, he told his family. While understanding why he hid it they started taking measures to work out his triggers and avoid them, it felt like he was an animal. Chained in a cage for fear he'd go feral at any moment someone stepped out of line. It was a lonely and maddening existence for him, constantly battling to keep his inner demon at bay while ruling a kingdom that now lived in fear of being the next one to die.

Then one day... it all changed.

With a simple, plain letter.
