Wren is a powerful Modified living in secret on a ranch in Ward Z. Though she possesses multiple psychic abilities like telepathy and projection, her veins do not glow silver when she uses them, allowing her to pass as a Prime. She operates with heavy emotional armor to protect herself and those she loves. Forced into the Command's Silver Block training program, she actively attempts to sabotage her own success to escape their control.

Cross is the disciplined, cold captain of the Silver Elite and the son of the General who rules the Continent. He recruits Wren into the Command's training program to monitor her after she causes a scene in public. Behind his flawless, symmetrical features and stern military demeanor, he hides an unexpected capacity for tenderness. He categorizes his duties carefully to survive the ruthless structure of the Command.

Kaine is a golden-haired, impish recruit assigned to Black Cell alongside Wren. His playful, flirtatious persona makes him a favorite among his peers and provides a contrast to the grueling nature of the Silver Block program. He often forms a trio with Wren and Lyddie during training exercises, bringing levity to the high-stress military environment.

Lydia, who goes by Lyddie, is a sweet and outwardly naive recruit from Sanctum Point. As the daughter of a Biotech executive and a Command Intelligence officer, she carries the ingrained prejudices of her upbringing despite her naturally gentle disposition. She frequently tutors Wren to help boost her written scores in the program.

Jim is a gruff, paranoid former Command colonel who deserted the military to serve the Uprising. He acts as Wren's surrogate father, raising her in secrecy on a ranch that covertly smuggles fleeing Mods to safety. He prioritizes Wren's survival above all else, burning off her physical identifying marks and forbidding her from using her abilities.

Xavier is the Second Lieutenant of the Silver Elite and the head instructor for the current session of the Program. He possesses rugged good looks and a highly disciplined approach to military training. Though he finds Wren troublesome, he watches her interactions with his superior officer with quiet amusement.

Tana is a Mod who works at an inn in Hamlett and maintains a covert telepathic link with Wren. Her veins visibly ripple with silver when she uses her abilities, forcing her to constantly wear long sleeves. She keeps her head down to avoid the attention of the Command soldiers who flood her village.

Roe is the illegitimate son of General Redden and an arrogant recruit in Black Cell. He actively antagonizes his peers and takes pleasure in the Command's violent methods. His presence in the program creates constant tension, as he searches for any signs of weakness or hidden Aberrants among the trainees.

Tyler is an instructor in the Program who teaches shielding classes to the new recruits. She holds deep prejudices against the Modified population, openly referring to them as monsters during her lectures.

Adrienne is a high-ranking leader in the Uprising who treats her operatives as expendable assets. She issues direct orders to Wren, pushing her to infiltrate the highest ranks of the Command regardless of the personal danger involved.
