Sarah Archer is a very disturbed person. As a child, she exhibited a dangerous split personality, but psychologists were duped into believing that the demented 'other half' had been supressed by treatment. In reality, the demented half had survived while the stable half had been all but destroyed. This remained unnoticed, as Archer took great pains to avoid attention. She developed her hacking talents to frightening levels, then set about creating as much mayhem as she could.
Under her hacking alias, Sagittaria, Archer was responsible for the crashing of one million servers in a single day, earning herself the monkier 'the Hate Crasher.' She faked her death during a government raid, protecting her true identity enough to allow her civilian guise as a medical expert to be hired by TruPharm Incorporated. She even went so far as to write a virus, Elogin (EE-lo-jin), whom she merged minds with. This link allows Archer to remain in telepathic contact with her creation, as well as tap into her viral powers.
Archer and Elogin both want to drive the Metaverse into total anarchy, which they are quite capable of doing, since Elogin has connections to anti-human groups even as Archer is a high-placed member of the True Force, an anti-nonhuman religious terrorist group. Even Lazarus, the leader of the True Force, is unaware of Archer's subversiveness.
The only people who have made the connection between Archer, Sagittaria, and Elogin are DaVinci and his friends, who are unable to convince the authorities of Archer's identity without exposing their own illegal hacking activities.
