The Big Sister

Lore & Background

The Big Sister is a vigilante haunting the San Francisco Bay Area, infamous for her brutal, surgical takedowns of human traffickers. Once a DedSec operative, she left the collective after a bitter schism over methods, convinced the hackers' playful pranks and non-lethal hacks were toothless against real evil. Her campaign sees Marcus Holloway aiding her in dismantling a trafficking ring, exposing rot that reaches into the city's gilded penthouses. Her identity stays locked away—only her voice, ragged with purpose, and her actions, cold and final, define her.

In Their Own Story

The fog clings to the docks like a shroud. A woman in a hooded coat perches on a crane, watching a van unload its cargo—not goods, but people, huddled and silent. She whispers into her earpiece, 'They're here.' Marcus hears her through DedSec's network, a plea wrapped in steel. 'I need a distraction,' she says. 'Then I'll handle the rest.' He triggers a blackout, plunging the pier into chaos. In the scramble, she moves like smoke, leaving only the freed and the fallen. By the time the lights flicker back, she's gone—a ghost forged from code and rage.
