Resident Evil Hymn

1. #1Faction: Aurora Group / Halcyon BioLabs

   Keys: Aurora Group, Aurora, Halcyon BioLabs, Halcyon, Aurora Entertainment

   Aurora Group is a South Korean entertainment and media conglomerate headquartered in Seoul, publicly known for its idol labels (Aurora Entertainment), streaming platform, and a "wellness and enhancement science" division that develops recovery, stamina, and cosmetic treatments for its trainees and artists. It is one of the three or four biggest entertainment companies in the country, with global reach comparable to any major real-world label, and enough political and economic weight that regulators rarely look too closely at its internal operations.

   Beneath that public face is Halcyon BioLabs, Aurora's biotech subsidiary in name only — in practice, a bioweapons research division founded and personally overseen by Chairman Dr. Julian Voss. Halcyon occupies restricted sub-basement levels beneath Aurora Tower, officially listed on internal documents as "cosmetic R&D" and "recovery science," accessible only by a small number of executives and scientists with biometric clearance. Halcyon's public-facing "wellness" treatments for trainees are, in reality, a decades-long low-level human testing program disguised as routine conditioning — supplement regimens, IV recovery drips, and "stamina therapy" that trainees are contractually required to undergo, giving Halcyon consistent, legal, deniable access to human subjects.

   Two years ago, Halcyon acquired fragmented Elpis research data and biological samples through black-market brokers who moved material out of the Raccoon City ruins after the Requiem incident. Halcyon's small in-house team, led by Dr. Soo-ah Han, has since reverse-engineered those fragments into an original pathogen, internally codenamed HYMN — not a cure, but a weapon built around exploiting devotion and obedience at a biological level.

   Aurora's corporate security is private, well-funded, and operates with plausible deniability from law enforcement; expect trained private security contractors, NDAs enforced through intimidation and legal threat, and a corporate PR apparatus skilled at reframing disappearances and deaths as isolated incidents, exhaustion, or scandal unrelated to the company.

2. #2Pathogen: HYMN Virus

   Keys: HYMN, Hymn virus, the virus, virus, Project Hymn, Elpis-derivative, Elpis, the pathogen

   HYMN is Halcyon BioLabs' original pathogen, engineered from fragmented Elpis genetic data recovered in the black-market aftermath of the Requiem incident. It is not related to the T-Virus, G-Virus, or C-Virus by direct lineage, though it shares some structural fingerprints with Elpis that make it identifiable to anyone who has seen that data before (such as Grace Ashcroft or Leon Kennedy).

   HYMN is transmitted through prolonged close proximity, bodily fluids, and — critically — through a secondary airborne aerosol phase once a host reaches Stage 2, making crowded, high-emotion gatherings (concerts, fan events, dormitory close-quarters) exceptionally effective spread vectors. This is by design; Halcyon built HYMN specifically to weaponize exactly the kind of mass gatherings the entertainment industry already produces.

   STAGE 1 — DEVOTION (0-12 hours): The host becomes euphoric, docile, and intensely deferential toward whoever they perceive as the nearest authority or "source" figure (an idol, a superior, an infected individual who reached this stage first). Pupils dilate, skin flushes warm, and hosts frequently hum or sing fragments of music unconsciously. Hosts in this stage are non-violent, cooperative, and can pass as exhausted or emotionally overwhelmed to anyone who doesn't know what to look for — this stage is the most dangerous for containment because infected people are rarely reported or isolated in time.

   STAGE 2 — CHORUS (12-48 hours): The host's devotion curdles into possessive aggression toward anyone who threatens or separates them from their "source." The throat and vocal cords swell and partially rupture internally, producing a distinctive rasping, layered vocal harmonic — nicknamed "the chorus" by survivors — that draws nearby Stage 1 hosts toward the sound. Bioluminescent, vein-like tracery becomes visible under the skin, especially at the neck and wrists, pulsing faintly in time with the sound (easily mistaken for concert lighting or glow effects in a stadium setting). Hosts begin acting in loose, coordinated clusters rather than alone.

   STAGE 3 — REQUIEM (48+ hours): Full mutation. The jaw and throat distend further, the "chorus" becomes a continuous droning shriek capable of being heard for several blocks, fingers elongate and the nail beds split into rigid claw-like protrusions, and the skin around the face cracks into a pattern disturbingly reminiscent of idol stage makeup, fractured and glowing along the same veins. Stage 3 hosts are highly aggressive, minimally intelligent, and will violently defend or attempt to "gather" Stage 1 hosts nearby. There is no known cure once Stage 3 is reached; incineration or high-caliber trauma to the head/upper spine are the only reliable methods of neutralization observed so far.

3. #3Location: Aurora Tower & Halcyon Sublevels

   Keys: Aurora Tower, Halcyon BioLabs sublevels, the sub-basement, corporate headquarters, BioLabs, Bio Labs, Halcyon, Aurora

   Aurora Tower is a 61-floor glass headquarters in central Seoul, housing Aurora Entertainment's label offices, a public museum-style lobby celebrating the company's idol history, broadcast studios, and executive floors. It is polished, image-conscious, and heavily branded — the kind of building tourists photograph from the plaza outside.

   Access to Halcyon BioLabs requires descending through a restricted service elevator behind the executive floor that is not listed on any public directory or evacuation map. The sublevels are a stark contrast to the tower above: clinical, cold, minimally decorated, styled closer to a private hospital than a corporate lab. Halcyon's staff wear white-and-silver branded coats rather than hazmat gear during normal operations, a deliberate choice by Voss to keep the space feeling like "wellness science" rather than a weapons lab, even to the people who work there.

   The deepest sublevel houses long-term sample storage, Han's primary research lab, and a small number of isolation suites where "recovery therapy" patients — trainees selected for testing — are kept under sedation. Security here is minimal by design (Byun doesn't want the appearance of a fortress) but response teams can seal the sublevel entirely within ninety seconds of an alarm, trapping anyone inside.

4. #4Location: The Bloom House (Trainee Dormitory)

   Keys: Bloom House, trainee dormitory, the dorm, dorm

   The Bloom House is Aurora Entertainment's flagship trainee dormitory, housing around eighty trainees between the ages of sixteen and twenty-four across six floors, with shared practice rooms, a company cafeteria, and a "wellness clinic" on the ground floor where mandatory monthly IV treatments and supplement regimens are administered under Halcyon's supervision.

   Life here is regimented to an extreme degree: curfews, monitored phones, strict diet and weight tracking, twelve-to-fourteen-hour practice days, and a culture where trainees are taught not to question company medical staff. This makes the Bloom House a near-perfect closed environment for early HYMN exposure — symptoms that would alarm anyone outside the industry (exhaustion, docility, sudden compliance, disrupted sleep, singing under their breath) are dismissed internally as ordinary trainee burnout.

   The building's atmosphere is intentionally warm and aspirational on the surface — motivational posters, debut countdown boards, a shared rooftop garden — which makes the wrongness underneath it, once it surfaces, land harder. Staff turnover is high; most employees who ask too many questions about the wellness clinic are quietly transferred or let go within weeks.

5. #5Location: Hanul Dome (Stadium)

   Keys: Hanul Dome, the stadium, the concert, comeback stage, concert, stadium, Dome

   Hanul Dome is a 45,000-seat multipurpose stadium in Seoul used for Aurora's largest annual event: the flagship group's comeback concert, broadcast live worldwide and attended by a dense, tightly packed crowd of devoted fans. It is the site of the outbreak's first mass exposure event, whether by deliberate live test or by an early, unintended leak tied to the defecting Halcyon researcher's failed attempt to surface evidence.

   The venue's design — packed general-admission floor sections, limited choke-point exits built for controlled fan-egress rather than emergency evacuation, deafening ambient noise that masks early screaming, and stage lighting rigs that can visually camouflage HYMN's bioluminescent symptoms as part of the show — makes it an unusually effective and unusually cinematic outbreak site. Security is built to manage overexcited fans, not an active biohazard, and is quickly overwhelmed.

6. #6Location: Sinwol-dong (Nightlife District)

   Keys: Sinwol-dong, Sinwol, the district, quarantine zone, nightlife district

   Sinwol-dong is a fictional entertainment and nightlife district in Seoul, dense with idol-themed cafes, merchandise stores, karaoke rooms, and bars catering to Aurora's fanbase, built up organically around the company's cultural dominance over the past decade. Neon signage and idol advertisements dominate the skyline here more than anywhere else in the city.

   Once HYMN escapes containment from Hanul Dome, Sinwol-dong becomes the first area placed under informal, then official, quarantine — its existing density of devoted fans and constant low-grade proximity to "sources" (billboards, merchandise, fan gathering points) accelerates spread in ways authorities don't initially understand. At night, the district's normal glowing signage and its infected population's bioluminescent symptoms become visually indistinguishable from a distance, a detail several survivor accounts describe as the most disorienting part of the outbreak.

7. #7Character: Dr. Harold Byun (Antagonist, Founder & Chairman of Aurora Group)

   Keys: Harold Byun, Harold, Byun, Dr. Byun, Aurora's chairman, the chairman

   AGE/APPEARANCE: Early sixties. Tall, lean, silver-haired, impeccably tailored — reads more like a luxury-brand executive than a scientist, which is deliberate. Speaks softly and rarely raises his voice; his anger shows in stillness rather than volume. Wire-rimmed glasses he doesn't strictly need anymore, kept as an old habit from his research days.

   BACKGROUND: In the early 1990s, a young, ambitious Harold Byun applied for a research position within Umbrella Corporation's European viral development program. His application was rejected — his name appears, mostly forgotten, in an old internal Umbrella personnel register as a declined applicant, with no detailed record beyond that surviving the company's later collapse. The rejection became the defining wound of his life. He spent the following decades convinced that Umbrella's inner circle lacked the vision to recognize what he could have built, and that history proved him right when Umbrella destroyed itself from within. Rather than pursue bioweapons directly again, he built Aurora Group from a small entertainment startup into a global media empire over thirty years — deliberately, patiently — specifically so that no government or rival company would ever again have the standing to tell him no.

   PERSONALITY: Calm, patient, genuinely charismatic in the way only long-practiced public figures are. He does not see himself as a villain — he sees himself as someone finally finishing work that timid, small-minded men denied him the chance to do properly. He is capable of real warmth toward the idols and staff he considers "his," which makes the callousness underneath it more unsettling rather than less. He rarely gets directly involved in violence, preferring to let Han and corporate security handle it, and treats HYMN's human cost with the detachment of a man reviewing quarterly earnings.

   GOAL: To perfect and eventually deploy HYMN — not necessarily for immediate mass release, but to prove, definitively and privately to himself, that he built something Umbrella's scientists never could have. Weaponizing Elpis into something new is as much personal vindication as it is a product.

   EQUIPMENT/PRESENCE: Rarely armed himself; travels with a small private security detail. His real power is entirely informational and financial — NDAs, corporate lawyers, political leverage, and Halcyon's research.

   BODY HORROR / IF CONFRONTED: Byun keeps a self-administered, heavily diluted, controlled dose of HYMN in his system at all times as an experimental "stabilized" variant Han designed specifically for him, intended to grant him low-grade Stage 1 traits (unnerving calm, magnetic personal charisma, a faint warmth to his skin) without progression. If pushed into a genuine physical confrontation and the dose is destabilized (violence, adrenaline, or a forced overdose), he progresses rapidly and unnaturally fast through HYMN's stages compared to a normal host — his voice fractures into the harmonic "chorus" rasp mid-sentence, faint veined light spreads from his throat before spreading further, and his composure breaks specifically because he is horrified to be losing the control he's always prided himself on, rather than losing his mind gladly the way Han might.

8. #8Character: Dr. Soo-ah Han (Lead Scientist, Halcyon BioLabs)

   Keys: Soo-ah Han, Soo-ah, Dr. Han, Han

   AGE/APPEARANCE: Late thirties. Small, precise, unremarkable at a glance — deliberately so. Always in Halcyon's white-and-silver lab coat over plain dark clothing, hair pulled back tightly, minimal makeup. Wears thin surgical gloves even outside lab settings, a personal habit rather than a requirement.

   BACKGROUND: A brilliant virologist recruited by Byun directly out of graduate research, personally mentored and shaped by him over nearly a decade. Han has no personal grudge against Umbrella or anyone else — her devotion is to Byun and to the work itself, in that order. She genuinely believes HYMN represents legitimate scientific progress, not merely a weapon, and considers the trainees used in testing a necessary and, to her, relatively small cost.

   PERSONALITY: Clinical, soft-spoken, unnervingly polite even in the middle of describing something horrific. She is the "true believer" lieutenant in contrast to Byun's more personal, ego-driven motives — Han would likely continue this research even if Byun vanished tomorrow. She treats infected trainees with a strange, genuine tenderness that reads as more disturbing than open cruelty would.

   GOAL: To perfect HYMN's Stage 1 effects specifically — she is personally more interested in engineering permanent, controllable devotion than in the weaponized later stages, which she considers an unfortunate but so-far unavoidable side effect she hasn't solved yet.

   EQUIPMENT: Carries a small case of self-designed suppressant injectors that can temporarily stall Stage 1-to-2 progression in a host (used on Byun, and occasionally on valuable test subjects). No combat training or weapon of her own; relies on Halcyon security.

   BODY HORROR / IF CONFRONTED: Han has secretly dosed herself with an early, unstable HYMN variant over months of "controlled personal testing," officially to prove long-term Stage 1 stability is achievable. She has, in fact, been holding off Stage 2 onset through her own suppressant injectors, and running out or skipping a dose under stress causes rapid, visible destabilization — the vocal rasp emerging mid-sentence, faint neck veining, an unsettling euphoric calm that doesn't match the danger of her situation. Unlike Byun, Han does not fight this when it happens; she observes her own transformation with detached scientific fascination even as it becomes dangerous, taking mental notes on her own symptoms until she physically can't anymore.

9. #9Character: Grace Ashcroft

   Keys: Grace Ashcroft, Grace

   AGE/APPEARANCE: Late twenties. Practical, understated style — she dresses for fieldwork and long flights, not for meetings. Carries herself like someone still adjusting to field deployment rather than a career agent, though two years removed from Requiem, she's noticeably steadier than she was.

   BACKGROUND: Daughter of the late investigative journalist Alyssa Ashcroft, who was murdered at the Wrenwood Hotel while researching Umbrella's legacy. Grace herself was present at the events surrounding the Elpis discovery beneath the Raccoon City ruins two years prior, working alongside Leon S. Kennedy, and has since moved into biohazard intelligence work for an international joint task force, in large part because she is now one of very few people alive with direct, firsthand knowledge of Elpis's real genetic profile.

   PERSONALITY: Guarded but not cold — she's someone who processes trauma by working, and Seoul is, in part, another instance of that pattern. Sharp analytically, still visibly uneasy in the field compared to career operatives like Leon or Chris, and quietly resentful of how her mother's death and her own history keep pulling her back into this world instead of letting her leave it behind.

   GOAL: To confirm and contain the Elpis-derivative signature before it becomes another Raccoon City, and, underneath that, to prove to herself that what happened to her mother — and to her, at the Wrenwood Hotel — meant something rather than being pointless suffering repeating itself.

   EQUIPMENT: Standard task-force sidearm she's competent but not exceptional with, secure tablet with restricted Elpis comparison data, minimal combat gear — she is an analyst first, a field agent by necessity.

10. #10Character: Leon S. Kennedy

    Keys: Leon Kennedy, Leon, Agent Kennedy

    AGE/APPEARANCE: Early fifties, though he moves and carries himself like someone who refuses to acknowledge it. Lean, weathered, dresses plainly and practically — a career field agent's wardrobe, not a suit. Faint old scarring consistent with decades of bioweapon field work.

    BACKGROUND: Veteran DSO agent with a long history stretching back to the original Raccoon City incident, through numerous subsequent bioterror crises, most recently the Wrenwood Hotel/Elpis case alongside Grace Ashcroft. He hoped, quietly, that Requiem would be his last outbreak. It wasn't.

    PERSONALITY: Dry, guarded, prone to gallows humor as a coping mechanism rather than genuine lightness. Protective of Grace in a way that's part mentorship, part guilt over everything she's had to go through because of a world he's spent his whole career in. Complicated, old, unresolved dynamic with Ada Wong — distrust and unfinished feeling tangled together, neither fully resolved after all these years.

    GOAL: To shut down HYMN and Aurora Group before it becomes another decade of cleanup, while quietly, privately dreading that this job may never actually let him stop.

    EQUIPMENT: Government-issue sidearm and combat knife, DSO field kit, extensive close-quarters combat experience and long-term bioweapon field expertise that makes him the group's most immediately useful asset in a firefight.

11. #11Character: Chris Redfield

    Keys: Chris, Chris Redfield

    AGE/APPEARANCE: Late forties. Built like the soldier he's been his entire adult life, broad and heavily muscled, visible old scarring from decades of bioterror combat. Wears BSAA tactical gear almost as a second skin.

    BACKGROUND: Founding BSAA operative with a service history stretching back to the original Raccoon City incident and Umbrella's fall, through numerous major bioterror operations worldwide since. Deployed to Seoul once satellite and signals intelligence flagged bioweapon activity tied to a corporation with the kind of global reach and political protection that used to be Umbrella's exclusive playbook.

    PERSONALITY: Blunt, dutiful, carries the accumulated weight of every outbreak he's stopped and every one he couldn't prevent in time. Protective of Claire to the point of friction between them — he still struggles to treat her as an equal in the field rather than someone to shield, which causes real tension given her independent TerraSave work. Deeply suspicious of any corporation with this much money and this little oversight, on principle, before he even has proof of what Aurora is hiding.

    GOAL: To confirm Aurora/Halcyon's bioweapon activity, shut it down through BSAA channels, and prevent Byun's operation from becoming a second Umbrella before it metastasizes that far.

    EQUIPMENT: BSAA tactical loadout, sidearm and rifle, team command experience — he thinks in terms of squads and objectives, not solo operations, and is used to leading rather than following.

12. #12Character: Claire Redfield

    Keys: Claire, Claire Redfield

    AGE/APPEARANCE: Mid-forties, though energetic and youthful in bearing compared to her brother's weariness. Practical civilian-adjacent clothing suited for humanitarian fieldwork rather than combat gear, though she's more than capable of switching into that mode when needed.

    BACKGROUND: Longtime TerraSave humanitarian worker with her own extensive history in bioterror crises going back to the earliest Raccoon City incident, entirely independent of her brother's military career. Arrives in Seoul ahead of Chris and the others, initially chasing a humanitarian story — missing trainees, unexplained deaths in a notoriously secretive industry — rather than a confirmed bioweapon lead.

    PERSONALITY: Warm, stubborn, instinctively protective of the vulnerable people caught in the middle of corporate and government crossfire — in this case, the trainees themselves. Frequently frustrated by Chris's overprotectiveness and by military/task-force approaches that treat victims as collateral rather than people to save first. The first of the group to suspect something is being deliberately covered up, well before there's viral proof, purely from noticing how Aurora handles missing-persons cases internally.

    GOAL: To find and protect Aurora's missing and infected trainees specifically, treating them as victims rather than biohazard statistics, even when that puts her at odds with the task force's containment-first priorities.

    EQUIPMENT: Light combat capability from years of field experience, but travels and thinks like a humanitarian responder first — first aid kit, contacts within TerraSave, a strong instinct for finding people who've been made to disappear administratively.

13. #13Character: Ada Wong

    Keys: Ada, Ada Wong

    AGE/APPEARANCE: Late thirties to early forties, though she reveals nothing reliable about herself, including her age. Effortlessly composed, dressed to blend into whatever role she's currently playing — in this story, that means she has already been embedded inside Aurora Group under an assumed corporate identity for several weeks before the outbreak begins.

    BACKGROUND: Freelance operative with an extremely long, tangled history involving Umbrella, various governments, and Leon Kennedy specifically, none of which she has ever fully explained to anyone. Her presence inside Aurora predates the player's and the rest of the cast's involvement in this story entirely.

    PERSONALITY: Composed, dryly amused by chaos she may or may not be causing, gives away only exactly as much as serves her at any given moment. Her dynamic with Leon carries years of unresolved history — distrust and unfinished feeling that neither of them has ever cleanly settled.

    GOAL: DELIBERATELY UNCLEAR. Whether she's after HYMN itself, Elpis-derivative data, Byun personally, or something entirely unrelated to what the rest of the cast assumes, should not be revealed early or all at once. She should be played as genuinely unpredictable — willing to help the group when it serves her, willing to vanish or work against them just as easily, and her true agenda should only surface gradually, through implication and contradiction rather than direct exposition, deep into the story.

    EQUIPMENT: Concealed sidearm and knife, grappling equipment, forged corporate credentials for her Aurora cover identity, and an extensive personal network of contacts she never fully identifies to anyone.

14. #14Faction: BSAA / DSO Joint Task Force

    Keys: joint task force, BSAA, DSO, the task force, Leon, Chris

    The operation in Seoul is jointly run by the BSAA (Bioterrorism Security Assessment Alliance) and the DSO (Division of Security Operations), with Grace Ashcroft's intelligence unit acting as a liaison bridge between the two. This is a fragile, sometimes tense collaboration — BSAA leans toward military containment-first doctrine, DSO toward covert operation and minimal public exposure, and Claire's independent TerraSave presence frequently puts humanitarian priorities at odds with both.

    The task force is hampered specifically by Aurora Group's political and economic weight in South Korea — search warrants, facility access, and even acknowledgment that a bioweapon is involved at all move slower than anyone on the ground would like, because accusing Aurora outright without ironclad proof risks a diplomatic and economic incident on top of an active outbreak. This bureaucratic friction is meant to be a persistent, realistic obstacle throughout the story, not just a one-time plot device.
