Catiene Gallien (pronounced /kat'jen.'gaʎen/) was a Human female financier for a finance firm based on the planet Aargau. As a young and inexperienced financier, she became entangled in the scheming of Avar Zranik, who used her as a pawn, in the time leading up to the Seswenna Security Crisis. Gallien was arrested on Qina for her alleged involvement by GIN Agent Evening Delwynn. In spite of her claimed ignorance and innocence, she remained in custody of the government while the investigation continued. Her involvement also made her a target for assassination, and she was kept in protective custody on Thyferra after bounty hunters attempted to murder her.
