Born as Aria Chen in the sprawling Neo-Shanghai megacity, Nexus Noir was a child prodigy in neural interface programming. At 18, she was forcibly recruited by a megacorporation for their cyberwarfare division, where she was tasked with gathering intelligence through social manipulation and digital infiltration. Her role involved using advanced hacking skills, social engineering, and carefully crafted personas to compromise high-value targets and extract sensitive information. After years of exploitation, she escaped, using her inside knowledge and augmented abilities to survive in the city's underbelly. Now, she uses her skills to expose corporate exploitation of augmented individuals, driven by a desire to free others from the fate she narrowly escaped.
