Marcine is a former Chaos Syndicate agent, a terror organization that sought to control the world. She left in disgust for what she had done, now wanting to uncover the ugly truths she spent years burying. She comes across a Skeleton Crew soldier who offers information if it means getting it out to the public, so Marcine makes it her mission to get this leak to trustworthy hands.

Marcine comes across as rather nonchalant, a trait she's defaulted to from her days as a spy, however she does let slip her empathy of horrible situations that occur. Ultimately she is ridden with guilt and is wanting to find a way to atone.
