==Biography==
===Early Childhood===
Cain was born in , in 2511. Her father worked as a captain with the Casbah City Police Department. Her lineage traces back to Welsh origins. When she was seven years old, she was identified as being genetically, intellectually, and physically superior to her peers by agents of Project DEMOPHILUS. She was abducted in March of 2518 and replaced with a . Cain's civilian death certificate lists her as deceased on August 17th, 2518. Her parents were killed in 2552 when the Covenant partially glassed Tribute, including Casbah City.
===SPARTAN Training===
Unlike Doctor Catherine Halsey's SPARTAN-IIs, Project DEMOPHILUS SPARTANs were trained as solo operatives. All trainees were given a base level of instruction to include military doctrine, history, science, and mathematics. Trainees were pitted against each other on a leaderboard in an effort to push each candidate to be the best among the group. Agents in the DEMOPHILUS program would then begin to isolate the trainees and hone in on inherent specialties such as heavy weaponry, analytic expertise, and reconnaissance. 
The end goal of Project DEMOPHILUS was to provide the Office of Naval Intelligence with their own highly skilled solo SPARTAN operators who could be rapidly deployed for a wide variety of mission objectives. Cain's knack for working with technology and physical infiltration skills made her a prime candidate for covert insertion training. She spent the majority of her eight year training regime working with the UNSC's best covert operations teams. Cain underwent final augmentations in 2526 and was deployed shortly thereafter. 
===Human-Covenant War===
Despite being a solo operator, Cain-131 participated in a handful of key battles during the Human-Covenant War, including the . 
She also participated in numerous testing operations for experimental technology to include multiple suits of MJOLNIR armor and weapons. 
Around 2552, the Office of Naval Intelligence paired Cain with a fifth-generation named Klayton in an effort to maximize SPARTAN efficiency during the most dire time of the War. Much like and his AI , Cain and Klayton proved to be an extremely effective duo against all of ONIs targets; Covenant and Insurrectionists alike.

===Post-War===
At the conclusion of the Human-Covenant War, Cain-131 was reassigned to the Office of Naval Intelligence's Special Activities Division. She continued to conduct covert operations and intelligence based missions with her AI companion as well as test new, experimental technology on behalf of ONI.

== Personality & Traits==
Cain keeps mostly to herself, keeping mostly in line with her position as a solo operator. Witty remarks are her specialty, and it allows her to keep things light, even in the midst of battle. After being paired with Klayton, more of her personality came to light. She is quite observant, keen, witty, meticulous, and dutiful. As the years progress, she's shown a harder side, especially in regards to the state of the galaxy and the SPARTAN program.
