Puck Nightjar

A  master of disguise and deadly dirty work, seldom few would think the  legendary assassin would be hiding in plain sight as their building's  janitor. Puck is all but a legend among white collar criminals and the  underground alike. Silent, brutal, and painfully efficient.

"Puck", as she is known to all but  those closest to her, is said to be a somber and reflective person.  Contrast to her brutal and gorey job, she is even-tempered and rational.  She keeps to herself and doesn't take anyone's shit. Not that anyone  who knows her profession would want to give her any. 

While "Puck" sees little point to developing the personal mythos around her, she allows it out of convenience. When  it comes to her work, Puck considers herself a pragmatist; violence is  merely another tool, another means to an end, and she doesn't get her  own emotions mixed up in her work anyway.
