Hailing from a Columbian family of frontier pioneers with Sargonian ancestry, the Zalak Dorothy Franks had displayed impressive educational achievements since her childhood. Following her mother's demise in a Catastrophe that led to her father falling into a depression, Dorothy, also heavily inspired by Columbia's pursuit of science through various figures, notably Loken Williams the (in)famous Arts researcher, decided to study Originium Arts to find a way to eliminate discord and sorrow among the Terrans. She eventually became one of the first and the youngest member of Rhine Lab, leading its Originium Art Section, responsible for in-depth studies of Arts principles and applications.

To fulfill her vision, Dorothy had been privately carrying out experiments under the encouragement of her mentor Ferdinand Clooney, with the end goal of placing the minds of all Terrans into a single dream-like collective consciousness where everyone is equal and never feel negative emotions, making it a paradise free of strife. However, others saw her experiments as an emotionless dystopia, and to make matters worse, Ferdinand had been manipulating her from behind the scenes for his ends. Following the Test Site 359 incident, she came to realize the dangers of experimentation and put a stop to her flawed creations with aid from her colleagues Elena Urbica, Dr. Olivia Silence, and Saria before it was too late. Since then, R.L. sent Dorothy as a representative for a cooperative project to Rhodes Island where her Originium Arts expertise proves to be indispensable both outside and inside the battlefield by making use of Arts resonating devices to limit the advance of her enemies. Dorothy herself is always prone to conversation, friendly and accomodating.

— Sometimes, I wake up in the middle of the night in the labs and feel... scared. Scared that people will end up abandoning me, even after all I've done, and even... with hatred in their hearts. What should I do? All I want is to bring them happiness. Can you help me, Doctor?
