Nocturne's creator, Anx

I have conceived an idea for a champion called Anx. The name is derived from the word "anxiety". I wanted this character to be related to Nocturne in the lore, and so it seems that Nocturne has loose ends on who created him, or, conversely, whether there are more like him.

I argue that Nocturne is a unique creature born from the mind of Anx, a lonely child, whose parents were murdered by Noxians during the Gray Order's exodus from Noxus. After their deaths, Anx became a mental case. He (or she?) developed manic depression and anxiety, and, as a result, he suffered from periodic hallucinations. While hallucinating, he would converse with an imaginary friend called Noc, named after "Noxus," and they would embark on hunts for the murderers of his parents. Failing to realize that he was no longer in Noxus, innocent people would fall victim to his violent hallucinations. His close friend, Annie, would do him a favor by incinerating the corpses, so that he would not be put in prison.

Upon reaching adulthood and earning enough money to move back to Noxus, Anx arranged his return, so that he could find the Noxians who murdered his parents. Upon arriving, however, Noxian guards arrested him and put him in jail. There, in jail, Anx was put under the watch of Thresh.

"Once a jailer who mercilessly brutalized all under his charge, Thresh was hanged from his own chains by the prisoners he had tortured. " -Thresh Lore

For 12 months, Anx was brutalized by Thresh, but not without retaliation. Whenever Anx retaliated, Thresh would ride him harder, until Anx was about to die, then he would let up. Over these months, Anx withdrew into his hallucinations for comfort, even as disturbing as they were. Noc was growing furious with Anx for not standing up for himself more. Anx was tired of hearing Noc complain. Then, one day, Anx told Noc to leave.

"He slaughtered everything he could find before summoners were able to magically confine him. After a period of intense study, League experts divined that Nocturne hunted summoners in their sleep, attacking them in a place where their magic was useless. This seemed to be his only purpose." -Nocturne Lore

Noc, taken aback, turned away from Anx and took as his name "Nocturne," vowing to come back for Anx's head in the real world, one way or another.

Without Noc, Anx was completely depressed. The next day, Thresh's beatings felt like they would be his last. Now at his weakest point, Anx retreated one last time into his mind where he once talked to Noc. Instead of his imaginary friend, he saw pain: any and every pain, all at once. Feeling the combined pain of every other human being, a magic like no other was awoken inside of him.

Upon returning to reality, Anx found that he was tied to a torture device, while Thresh was waiting nearby in a chair. After being thrown back into his cell, Anx began to talk to the other prisoners with his new magic, and they devised a plan to kill Thresh the next week.

On the day that he killed Thresh, Anx stared him in the eyes as he hung him. The one thing Anx did not see in Thresh's eyes was fear. There was no fear. There was no pain.

Ending:
