Kay, here's what I've got.
Jonas, NE changeling Rogue 4 (Using Changeling Rogue substitution Levels from RoE)
Jonas had a hard life. He was constantly abused by his "father" and despised by his mother, as neither of his parents were changelings. He was the result of a changeling's deception of his mother, and as such was a breathing symbol of marital stress. Saddest of all, he spent much of his youth unaware of his race. He was trained, in a pavlovian method of beatings, to at least look like his father, from the age of six months. He went about his life not changing, because the instinct to change had been beaten out of him. So he was being punished by his mother and father, without knowledge of his crime. Finally, when he was ten, he fled a beating at the hands of his father, and, ducking down an alley hoping to evade his father's pursuit, wished he was somebody, anybody else. His 'latent' changeling powers kicked in, and when his father approached the alley, he found a poor beggar child, and continued on. Jonas, a bright child under his emotional trauma, realized he must be a changeling. He then returned home, buoyed by the knowledge that he could escape his father's wrath if necessary. He was discovered changing a time or twice, and the vicious beatings that followed taught him to change very quickly when he did. One fateful day, he was walking home with a classmate, and they got into an argument. In his anger, he shoved his friend. His friend stumbled, tripped off the walkway, and fell to his death. Jonas knew that people were hurt very badly indeed for killing people, so he did the first thing he thought of: he became his friend. He went to the friend's house, and impersonated him for several days. When he realized that it was getting too hard to continue, he staged his friend's runaway, and moved on. Knowing that now he could be anyone, he began a life of imitation, pretending to be people at social gatherings, attending Morgrave University under an assumed name, where he received exemplary marks, but really was only there to study others more intently, learning quirks and manners of speech. Eventually, he took to crime, but always impersonating someone else, so that the blame fell on another's head. he continued in this, even when he was eventually caught, through use of divinatory magic. he viewed the magic as a hurdle to overcome, and trained himself to recognize its presence, and to only think things appropriate to his current guise when it was in effect. He's been planning to take further steps once he finds them, so that soon he'll be able to pretend to be whoever he wants, and no one will be able to prove him wrong.
