Priscilla Roletti is an agent with Shadow Ops.
That small but effective covert organization is "linked to the CIA", which allows them to get the really nasty jobs the Agency would love to disavow but which need doing nevertheless. It is headed by John Derlin, a highly experienced former operative who wears an eye patch as a souvenir of his action during a previous war. Housed in several floors of a black-tinted high-rise office building, Shadow Ops has had several very successful years and earned their reputation, one of the reasons being the talents and drive of Roletti.
Though successful, Roletti was human. As her boss saw it, "Priscilla was one of the best agents to ever come through the ranks since Shadow Ops was founded. John had complete trust in her. That was something he didn't have with many of his agents under him. He knew that when she was on a job, she followed it through to the end and made sure there were no loose ends. However, she was far from perfect... there was still a lot of rough edges that needed to be smoothed out, and fast because in this line of work, running around with a chip on your shoulder and a mad at the world attitude would lead to your demise pretty quickly."
He would observe that she could be "brutal, blood thirsty, and very reckless" and he worried she was moving to the point of needing to be pulled off field duty when her life, and her attitude, changed. The manner of this change makes up a good portion of first recorded adventure as a flashback [and will not be spoiled here].
Now, when we first meet her, she is in her early 30s. Her drive and determination are still as strong as ever and her ability to carry out her mission with whatever intensity or viciousness was required had not diminished but the shoulder chip was gone and when the action was over, she gladly comes home to her two children, Patricia, around 10 years old, and Jonathon, 5.
