Abby Addams is agile for her build. Tall and muscular, she's a free-running expert who has bad luck with the guys - often coming across as intimidating when all she really wants is a night out on the town. The fact that she keeps a knife on her person at all times does little to alleviate their discomfort.

Despite wearing the robes and using the hidden blades of an Assassin, she's not actually a member of the Brotherhood. One night, she was practicing free-running through a construction yard with intentions of setting up a filming session the following day when she heard voices coming from a half-built skyscraper across a vacant lot. Curious, she sprinted closer and eavesdropped on the speakers - one man draped in flowing, white robes, and a woman wearing a crisp business suit - a gun aimed square at the man's head. A brief scuffle between the two left the woman with a hidden blade lodged in her gut and the man bleeding profusely from a gunshot wound to the stomach.

Abby, without a method to alert authorities (she'd left her cell phone at home), dashed to the fallen people in a vain attempt to help. The woman was already dead, but the man was bleeding out and wasn't long for this world. Gasping for breath, the robed man pleaded for her to strip him of his robes and blades 'before they were discovered.' He then issued a faint warning, that when she left she shouldn't tell anybody of what she saw, that the police weren't to be trusted. He tried to tell her more, but she only caught a few words as delirium laid claim to him - something about Assassins and Templars. She stayed by his side until he passed away, and fulfilled the man's wishes by laying claim to his possessions and fleeing the scene of the crime.

Shaken, Abby returned home for the evening and passed out with the man's belongings on a chair near her bed. The following morning, she woke up and turned on the news - fully expecting there to be a story about the double murder at the construction site - but nothing. Nor the day after that, or the day after that. Local radio stations and newspapers remained equally as mum, leading Abby to the conclusion that she'd seen something nobody else was meant to.

One day, after a long shift at work, Abby was about to enter her apartment when she heard a woman shriek for help - around the back the building. Abby, always nosy, dashed to the back of the alley, saw that two large men had cornered a young woman - no older than nineteen - and Abby was smart enough to put the rest of the puzzle together. Before she could do anything, though, one of the men spotted her - yelled, began to chase after her, brandishing a pistol. Abby turned around, fled - hated to have to leave the girl to fend for herself, but there wasn't much she could do against a gun. She heard the man charging after her, but she had one benefit he didn't: the ability to free-run. She pulled around the front of the building and begun to climb up its face, up to her floor - her window. She popped it open and threw herself inside, and was out of sight by the time the gunman had left the alley.

That's when she saw the robes and hidden blades, still sitting on the same chair for weeks, gathering dust. It gave her an idea.

Abby threw the robes on and strapped the hidden blades on in a rush. She peered out her window, saw the gunman had given up on her and disappeared - good. Clambering outside, she continued to vault herself to the top of the building, dashed across the roof, and glanced down into the alley, once again looking at the scene she'd stumbled across before, but this time with a different vantage point.

She flexed her wrists - saw the hidden blades pop from their sheathes, then slide back into place when she relaxed. Easy enough to use, then.

The two men closed in on the girl. Abby leaped downward, bounding off parts of the building to keep her from hitting terminal velocity - then popped her blades as she landed on one of the goons, undoubtedly breaking his legs, jabbing the blades hard into his back. Before the other guy - the one with the gun - could react, she'd retracted the blades and punched him hard in the gut, popping them again - the blades sliding cleanly into his stomach. The girl they'd been harassing shrieked and fled, leaving Abby panting and gasping as she stood victorious over two men who she'd probably just killed.

Still, that one event inspired her to use the robes and blades to adopt a sort of vigilante persona, which she uses in tandem with her free-running ability, helping those that can't help themselves. She's not out for any glory, and aside from a quick quip, she's in and out of a crime scene as fast as possible. But people in the streets are talking about the tall, hooded woman who slays criminals with blades on her wrists. It keeps many ne'er-do-wells in line, but she'd better be careful not to draw too much attention to herself...
