Ethnicity: Alexa's human family is of Chelaxian descent, but have been in Korvosa for several generations.
Religion: Alexa is one of those people who doesn't devote herself to one god specifically, and is not very religious but will casually offer prayers to anyone in the pantheon when appropriate. The deities she favors more are Nethys and Calistria.
Day job: Im thinking that after she left the Academae, Alexa has been supporting herself with a job that she doesn't enjoy and considers somewhat beneath her. Working at an inn/tavern? I am open to suggestions if this could maybe tie in to another character.
Family: Alexa no longer has any contact with her father, who was formerly very distant but still provided for her mostly to keep her away from his family. She's only briefly met her stepmother and human half-siblings and doesn't really think about them.
Friends: She had a reasonable number of school friends at the Academae, but after the arrest and dropping out, most of them quietly stopped talking to her. The exception is a young man named Dask who she was fairly close to, and he's the person who helped to get her out of the charges as well as finding out that Lamm was most likely responsible for her being framed.
