Elsa came to Washington, DC to attend Georgetown as a college student and decided to stay. While a student, she majored in political science and took some internships among the school's prestigious alumni. She competed her BA as Elsa, but had already begun to develop her alias, which is now the face she always shows the world. The real her, even.
But the real her only feels useful in DC where she has contacts and, more importantly, where her work really makes a difference in the world.
She actively lives under the name she used when she went to school. And legally, that name is working for a government contractor. But deflecting is a wonderful thing, and so far, her silenced gun hasn't drawn the attention that would cause her any trouble. Her home is a brownstone townhouse, three floors. Technically it is also the headquarters of her legitimate business.
Right now, Skadi gets her money buy taking different types of mundane contracts, organized by her legal identity, Elsa. Most of her contracts are not wet work, although she has in the past taken kill contracts. Most of the work she does is hunting. Things. People. Mostly people. Sometimes an artefact for some avid collector who was desperate and could not get a museum to sell. Or art. She's stolen art a few times. It's her least favorite, because of the stakes involved. For her.
She spends her money on her house, her bike, and keeping her tech up to date.
