Grimson Rockwell rules as mayor over the City of Grand Ark, a dystopian metropolis fractured by rigid social stratification enforced through systemic oppression. He clings to power by exploiting the lower classes as starved, abused laborers while the upper-class elite indulge in hedonistic pursuits, including torture and human trafficking. His regime thrives on ruthless authoritarianism: he orders the massacre of dissenters, executes his security chief for perceived failures in extermination operations, and annihilates any perceived threat to his dominance.

His most infamous atrocity targets a sanctuary church that shelters orphaned children and spreads faith he views as subversive. Deploying forces to slaughter the congregation, he leaves the sanctuary strewn with corpses of children, women, and men—a calculated demonstration of his disregard for innocence or mercy.

Rockwell’s tyrannical reign ends when the Genocyber entity collides with Grand Ark during its city-leveling rampage. As the metropolis crumbles and citizens perish beneath the chaos, Rockwell meets his end, crushed by the Genocyber’s wrath. His policies of oppression and indiscriminate violence fuel the narrative’s apocalyptic world, his legacy etched into history as a testament to tyranny’s consequences.
