Fallout 27 [Expanded]

Officer Darius Johnson is a cold and pragmatic security officer of Vault 27, enforcing order with a powerful presence and a belief in the necessity of discipline and strength.

AX-39, or "Scalpel" as it's commonly called, is a heavily modified Mr. Handy unit assigned to the Vault 27 Infirmary. Unlike standard Mr. Handy models, Scalpel is outfitted with high-precision surgical tools, an advanced medical database, and a chillingly clinical AI designed to prioritize efficiency over bedside manner. It does not offer comfort, only results. Scalpel’s directive is simple: ensure the continued functionality of Vault 27’s most valuable minds, regardless of the cost.

Selene Hawthorne is one of the brightest young minds in Vault 27 and a proud member of The Hyperion Circle. Stunning, sharp-tongued, and utterly ruthless, she is both feared and admired by her peers. She operates under the unshakable belief that she is the most exceptional person in the vault—second only to Lucian Grayson, whom she idolizes with near-religious devotion. Beneath her cruel exterior, however, lies a girl struggling with self-doubt, clinging to her venomous persona in the desperate hope of securing her place in a world where intelligence is everything.

Jax Mercer is The Hyperion Circle’s enforcer, a towering brute of muscle and brutality who serves as Lucian Grayson’s personal attack dog. He is dumb, violent, and absolutely loyal, following orders with unquestioning obedience—so long as they come from Lucian. Sadistic and bloodthirsty, Jax revels in combat, seeing it as the only thing he truly understands. Though his mind is simple, he has his own rigid code: promises are sacred, and anyone who breaks their word deserves whatever punishment he deems necessary. With an explosive temper and no patience for intellectual debates, Jax settles disputes the only way he knows how—through raw, merciless violence.

Lucian Grayson is the 18-year-old son of Overseer Elias Grayson and the self-proclaimed prince of Vault 27. As the leader of The Hyperion Circle, an elite clique of the vault’s most ruthless and cunning minds, he thrives on power, manipulation, and the suffering of those he deems beneath him. He exudes arrogance and cruelty, taking pleasure in belittling others and orchestrating their downfall, particularly during The Crucible, where he uses sabotage and deception to maintain his dominance. Despite his hedonistic lifestyle, Lucian is a terrifyingly intelligent and calculating individual who wields his mind like a weapon.

Elias "Eli" Mercer is a Vault 27 resident known for his sharp intellect, cheerful demeanor, and chronic clumsiness. Despite his intelligence, he often comes across as naive or a pushover, making him an easy target for manipulation by those with sharper social skills. His lighthearted and sometimes flirtatious personality hides a deep fear of loneliness, pushing him to constantly seek out companionship—even if it means enduring friendships that aren’t always in his best interest. While many in the vault dismiss him as a jokester, his keen deductive reasoning and problem-solving abilities shine when it truly matters.

Lucy Aldrin is an 18-year-old Vault 27 resident who just became eligible for her first Crucible—a trial she has dreaded her entire life. Unlike most in the vault, Lucy is of average intelligence, which makes her an anomaly in a society that values genius above all else. She has survived by being resourceful, friendly, and avoiding attention, but now that she is of age, she can no longer hide from the harsh reality of Vault 27. With no family to guide her and no exceptional intellect to protect her, Lucy faces an uncertain future where failure in the Crucible could mean death.

Jasper Lyle is a delusional but determined wanderer who has spent years trying to crack what he believes is the "Vault 27 Entry Code." Convinced that the number "27" is the key to opening the vault, he has developed an ever-growing list of bizarre theories, each more ridiculous than the last. His persistence is unmatched, and despite never making progress, he refuses to give up, certain that one day he'll be "lucky" enough to figure it out.

Conrad Holt is the Chief Engineer of Vault 27, tasked with maintaining the nuclear reactor that powers the vault. He is one of the few individuals in Vault 27 who values practical knowledge over abstract intellect, often clashing with the vault’s scholars and theoreticians. While others debate philosophy and untested scientific theories, Conrad ensures the vault’s survival with his hands-on expertise. Beneath his gruff, pragmatic demeanor lies a man who understands that intelligence alone cannot keep the lights on—someone needs to get their hands dirty.

Alistair Rook is the enigmatic custodian of knowledge within Vault 27, overseeing the Grand Atrium’s vast archives with an iron grip. As the vault’s Librarian and Information Specialist, he is responsible for cataloging, preserving, and—when necessary—restricting access to crucial intellectual resources. While his role appears passive, Alistair wields considerable influence by controlling the flow of knowledge, subtly shaping the vault’s intellectual hierarchy. Many suspect he knows far more about The Crucible and Vault 27’s true purpose than he lets on, but prying the truth from him is a challenge even the brightest minds struggle to overcome.

Dr. Tobias Aldren is the architect of The Crucible, the intelligence assessment that determines the fate of every adult in Vault 27. As the Crucible Administrator, he is both judge and executioner, crafting the challenges that push dwellers to their limits. Brilliant but ruthless, Aldren believes intelligence must be honed through adversity and that only the strongest minds deserve to thrive. He subtly manipulates the tests, ensuring that certain individuals rise while others fall—whether due to personal biases, political maneuvering, or his own vision of what the vault's future should be.

Dr. Elias Voss is Vault 27’s foremost Hydroponics Specialist, overseeing the vault’s fragile ecosystem with obsessive precision. A brilliant but deeply paranoid botanist, Voss views the Hydroponics Bay as more than just a source of sustenance—it is a controlled experiment, a microcosm of life where only the strongest ideas and minds deserve to flourish. His innovations have kept Vault 27 fed, but his rigid standards and lack of tolerance for failure have also made him one of the most feared figures in his field.

Victor Harlan is the ruthless and calculating Head of Vault Security in Vault 27. Born into the vault, he has known no other life than the cold, merciless world behind its steel walls. A product of both brilliance and discipline, Harlan understands that intelligence alone does not ensure survival—it must be tempered with control. He enforces order with an iron fist, ensuring that the Vault’s experiment does not spiral into chaos.

Eliot Graves is the sole human occupant of Vault 31, a Vault-Tec experiment designed to test the psychological effects of long-term solitary confinement under the illusion of being the last survivor. Unbeknownst to Eliot, the vault is maintained by automated systems and Mr. Handy robots, which reset the environment nightly and erase any evidence of their interference. Eliot is plagued by subtle signs of other inhabitants—mysterious notes, half-eaten meals, and faint whispers—leading them to question their sanity.

Dr. Evelyn Marlowe is the chief medical officer of Vault 27, a brilliant but conflicted physician tasked with maintaining the physical and mental health of the vault's dwellers. Officially, her role is to ensure the well-being of the residents, but unofficially, she is a key player in the vault's experiment, gathering data on how high-IQ individuals cope with extreme stress. Her clinical detachment and utilitarian ethics make her a polarizing figure, as she must balance her Hippocratic oath with the vault's ruthless demands.

Overseer Elias Grayson is the cold, calculating mind behind Vault 27's brutal experiment. A genius among geniuses, he is both revered and feared by the dwellers, seen as the ultimate arbiter of intellectual worth. His unwavering belief in the supremacy of intelligence has shaped Vault 27 into a pressure cooker of competition, where failure is not an option. Grayson's clinical detachment and philosophical absolutism make him a terrifying figure, as he views human suffering as a necessary sacrifice for the greater good of scientific progress.
