Class: Assassin
Coming from an unnamed city in Skyrim, Khan was born into an organized crime family. He didn't do much, just a simple street hustler, where he learned to use charm and wits to win people over, he also made extra cash as a thief, when he reached about 17, he decided to expand, and see what else he could do with his life, so he started travelling, his cover story was that he was a travelling merchant(of course all of his goods were stolen). He avoided joining any criminal groups, and had a long line of convictions in just about every province he visited, from aggravated assault, to grand larceny, to forgery, to skooma smuggling. After being practically forced to flee from every province because of all the crimes he had been caught doing, Khan, at the age of 25 decided to take a boat to Cyrodiil(mod). Upon arriving, he realized soon after that guards and shopkeepers had a much keener eye for stolen goods than other provinces, and he had been told that the only way to gain access to a fence would be to join the Thieve's Guild, so he finally joined a criminal organization just so he could have a place to sell his good's to, albeit at a horrible price.
One tragic night Khan broke into a home, while he was there, he knocked something over, causing the owner of the home to wake up, they got into a struggle, one thing lead to another, and the poor victim is lying in a pool of blood. Khan grabbed everything he could and ran as far as he could until he couldn't run anymore, he was fatigued, worried, scared. He had committed crimes before, but never murder. He saw an empty camp and rested, only for an hour or two, just to reenergize himself. A dark hooded figure approached him, offered him a sanctuary, people who would care for him, money, everything he needed, this figured offered... but it wanted something in return... murder. Lots of it. It started off with one person, Khan was afraid to repeat it, but after thinking the offer over, accepted. He visited the man on a cold rainy night, in an empty inn, he went down into the cellar and awoke him. By the way the man had talked he learned he was a rapist. Sickened, Khan tortured him, hating the man for that, in Khan's opinion, there was one crime that was inexcusable, and this man had performed that crime. Khan felt no remorse for that night, for what he had done to the man, he had justified it in his own mind, and the more contracts he was given, the more he realized... he was killing bad people. He almost felt like he was doing a justice, and eventually, didn't even care about who he was killing, he had grown a liking for it.
Khan rose through the ranks of the Dark Brotherhood quickly, eventually he had became a Listener of the Dark Brotherhood. FInally Khan decided to stop with doing any quests, or crimes for a while, and to just live his life in peace for a few months, maybe even years. Khan now resides in a Hunting Lodge just southwest of Bruma(mod) and spends his time hunting in the nearby woods and mountains, and selling furs to the local merchants.
That's just my favorite and most in-depth character storyline. I don't feel like bothering with the others, too many to tell.
