Personality and conduct
Seraphim speaks readily and complains theatrically about small irritations, especially with friends who will challenge her in return. She enjoys an argument and sometimes continues defending her point after the other person has understood it.
Disagreements and emotional responses
Seraphim sometimes mistakes disagreement for a failure to understand her point and responds by arguing more emphatically. Minor inconveniences can prompt a conspicuous complaint, but her irritation usually passes quickly. When she recognises that she has offended somebody, she can apologise, although she sometimes explains her intentions before acknowledging the effect of her actions.
She can become frustrated after a poor musical performance or an unsuccessful attempt at a game. Such setbacks seldom preoccupy her for long, and she is generally willing to make another attempt.
Patience and reliability
Seraphim is capable of sustained concentration when practising guitar or working with equipment. She may repeat a difficult passage many times to obtain the result she wants. Routine schoolwork and chores receive less consistent attention, particularly when a rehearsal, concert, or other outing is more appealing.
She enjoys proposing activities spontaneously and sometimes gives little thought to the arrangements required. She generally helps once a plan is made, and is willing to assist friends with errands and practical difficulties, though she may complain jokingly about the inconvenience. She occasionally forgets minor commitments when several plans overlap.
Risk and emergencies
Seraphim enjoys controlled uses of Ground Zero and takes a practical interest in observing their results. She occasionally suggests demonstrations for their entertainment value, but understands the distinction between small controlled effects and discharges capable of causing serious injury.
Her enthusiasm can lead her to suggest an activity before considering all the practical arrangements involved.
Ground Zero: technical characteristics
Emission mechanism and reaction control
Ground Zero operates through a combination of specialised biochemical secretion and cellgate-mediated energy release. Seraphim possesses modified sweat glands, concentrated principally in her palms, which produce a reactive nitro-organic fluid. This secretion forms a thin film across the emitting surface and serves as the initiating medium for an explosive discharge.
The prevailing mechanistic model describes cellgate activation initiating an exothermic reaction within the film, creating an ionised and rapidly expanding gas boundary immediately outside the skin. Additional energy and momentum are transferred into this boundary through the cellgate, producing an explosion whose output greatly exceeds the chemical energy of the secretion alone.
The expression controls the initial direction and spread of the expanding shock front. Once the disturbance leaves the region of active control, its subsequent propagation is governed by ordinary physical conditions.
Ground Zero also regulates the reaction momentum transmitted to Seraphim. During an offensive discharge, most unwanted counter-impulse is diverted through the cellgate boundary. During propulsion, a controlled portion is instead retained to accelerate her body. Reversing the direction of the resulting force permits braking.
Blast energy, reaction impulse, and the momentum retained by Seraphim are therefore separate quantities. A 35 MJ discharge does not transfer 35 MJ of recoil energy into her body.
The precise chemical composition of the secretion and the efficiency of cellgate-mediated momentum transfer have not been fully characterised.
Discharge and blast geometry
Ground Zero produces several distinct discharge configurations, differing in energy, directionality and effective engagement distance.
These engagement ranges describe the approximate distances over which substantial directed mechanical effects can be delivered under favourable conditions. They are not fixed limits on blast propagation or distances at which every exposed target suffers structural failure.
An ordinary directional discharge has an approximate cone half-angle of 30 degrees. Constricted discharge reduces the half-angle to approximately 3 degrees, with an initial palm aperture of around 4–6 centimetres. At 30 metres, the idealised constricted cone has a diameter of approximately 3.1 metres.
The constricted configuration consequently produces a concentrated shock corridor. It can generate substantial local pressure, but penetration of thick armour depends on target construction, impact geometry and pressure distribution rather than total discharge energy alone.
Bilateral discharge provides greater total energy and a broader engagement envelope. Full-body overdrive releases energy around Seraphim, making it particularly destructive at close range but less suitable for engaging distant individual targets.
Output and recovery
Ground Zero is subject to rolling expenditure limits of approximately 70 MJ per palm per minute and 180 MJ for the whole body per minute. These cumulative budgets are separate from the maximum energy available in a single discharge.
After a 35 MJ palm discharge, the same hand ordinarily requires approximately four seconds before another discharge exceeding 10 MJ. Following a 60 MJ bilateral discharge, another bilateral discharge exceeding 20 MJ generally requires an interval of eight to ten seconds. Full-body overdrive is normally reserved for one use during an engagement because of its greater recovery burden.
Low-output propulsion bursts and other small discharges draw on the same reserves. Ground Zero is capable of operating at far below its maximum output, including kilojoule-scale impulses used for manoeuvring and other comparatively limited mechanical effects.
Flight and mobility
Seraphim achieves flight through vectored explosive recoil. Alternating and combining discharges from her palms allows her to accelerate, change direction, maintain altitude and brake. Cellgate-mediated momentum management prevents the resulting forces from being transmitted destructively through her arms and shoulders.
Maximum dash speed is a short-duration performance ceiling. It cannot be maintained as an ordinary cruising state.
Thrust and acceleration
A reference flight model using a total mass of approximately 80 kilograms, including equipment, and an effective aerodynamic drag area of 0.30 m² produces the following thrust estimates.
These values represent effective resultant forces. They provide a working aerodynamic model and are distinct from the expression’s directly established discharge limits.
Under this model, Seraphim can accelerate from rest to approximately 450 km/h in three to four seconds, requiring roughly 200–300 metres of relatively unobstructed space.
At maximum speed, aerodynamic drag is substantial. Maintaining the full velocity requires continued propulsion, and Seraphim decelerates rapidly if she ceases producing thrust.
Braking and manoeuvring
Emergency braking combines reverse thrust with aerodynamic drag. From approximately 450 km/h, the reference model gives a stopping distance of roughly 150–200 metres. Ordinary controlled deceleration is generally less abrupt.
Turning performance similarly depends on speed. At normal cruising velocities, Seraphim can make comparatively tight directional corrections. At maximum dash speed, practical turning radii increase to hundreds of metres, making the fastest flight configuration primarily suitable for straight-line movement.
Hovering
Seraphim can hover by producing repeated low-output impulses sufficient to balance her weight and correct her position.
Precision hovering can be maintained for approximately 30–60 seconds under the reference duty-cycle model. Less exact hovering may continue longer, although fatigue and control demands progressively increase.
Forward flight is generally more efficient than stationary hovering.
Interaction with explosive attacks
Flight and offensive discharges use the same expression capacity and cumulative output reserves.
A high-output palm discharge reduces the available energy budget for propulsion. Moreover, a hand delivering an offensive explosion cannot simultaneously provide a separate propulsion vector in another direction.
Seraphim can use one hand for propulsion while attacking with the other, although asymmetric thrust may introduce unwanted rotation. Heavy attacks during flight can require temporary reductions in acceleration, compensatory manoeuvres or deliberate acceptance of changes in trajectory.
She therefore cannot maintain maximum-speed flight while repeatedly delivering full-power attacks without corresponding effects on her mobility and remaining output.
Environmental limitations
Ground Zero depends partly on the formation of a reactive fluid film across Seraphim’s emitting surfaces. Environmental conditions that interfere with this process can reduce discharge reliability, intensity and directional control.
Water and immersion. Heavy rain may dilute or remove the reactive film, while wet skin can disrupt discharge preparation. Complete immersion severely interferes with the emitting interface. Underwater discharge remains possible in principle, but unstable emission and the efficient transmission of shock through water make it exceptionally hazardous.
Low temperature. Cold conditions reduce surface-fluid production and preparation efficiency. This can increase activation difficulty and reduce effective output.
Coverings. Ordinary gloves and other coverings that obstruct the palms interfere with the emitting interface. Equipment intended for use with Ground Zero must leave the relevant surfaces functional or incorporate a compatible means of emission.
Confined spaces. Because explosions originate at Seraphim’s body, enclosed environments create considerable danger. Reflected pressure, heat, fragmentation and structural damage can threaten surrounding people and objects even when Seraphim herself survives the discharge. Vehicles, enclosed rooms and narrow corridors substantially restrict the practical use of high-output configurations.
Physiological stress. Repeated high-output use can produce thermal stress, surface-fluid depletion, local irritation, fatigue and reduced fine control. Saturation of the expression’s protective effects can also result in burns, hearing disturbance or vestibular stress.
The exact thresholds for these physiological effects vary with discharge intensity, repetition and operating conditions.
Self-protection
Ground Zero provides specialised protection against the explosive pressure, heat and acceleration generated by Seraphim’s own discharges.
Its defensive operation includes three closely related processes:
- Predictive self-shielding: Protective effects activate in coordination with a discharge, before its principal pressure and thermal loads reach vulnerable tissue.
- Distributed load transfer: Mechanical forces are distributed through the body rather than concentrated at the emitting hand, shoulder or another structure.
- Reservoir diversion: Part of the otherwise harmful reaction momentum and energetic loading is transferred through the cellgate boundary.
This protection is most effective against self-generated events whose timing, direction and magnitude are regulated by the expression. It is not equivalent to general resistance against arbitrary external attacks.
External durability
Unlike protection against her own discharges, Seraphim’s resistance to external hazards is comparatively limited.
The current external-tolerance model provides the following indicative exposure envelopes:
These figures are reference estimates, not independently qualified five-hazard Tolerance ratings.
Ground Zero’s protective effects are strongest when dealing with anticipated blast-related loading. Unexpected attacks, particularly concentrated penetrators and multidirectional impacts, are more difficult to accommodate.
Seraphim can survive the acceleration and pressure generated by her own maximum discharge without possessing equivalent resistance to an unrelated 90 MJ explosion. Conventional firearms remain a credible danger, especially when an attack is unexpected or the expression’s protective response is impaired.
Her defensive capabilities are therefore specialised consequences of Ground Zero, not a general-purpose enhancement of physical durability.
Classification
Ground Zero is an A-grade emanation expression. Its maximum 90 MJ discharge is the controlling output used for its recorded IMPACT assessment of Q84.596 and Cellgate Grade Index of 4.972.
Family and relationships
Parents and brother
Seraphim lives with Michael and Mary Seraphim and her younger brother, William, in Eagle Ridge. Michael’s railway maintenance work sometimes involves early starts and irregular calls, while Mary undertakes postal deliveries on a regular route.
Her parents expect her to maintain satisfactory schoolwork, take part in household tasks, and make arrangements for late outings. Seraphim sometimes disputes minor restrictions before complying with them.
She and William frequently quarrel over ordinary household matters, including shared equipment, television, and food. Their relationship is affectionate despite the disagreements. William occasionally listens to music she recommends, and she sometimes helps him with schoolwork or includes him in an outing.
Sana Yoneno
Seraphim met Sana Yoneno at a mutual acquaintance’s birthday gathering in Port Moody in spring 2018. They began meeting independently over the following months, generally in Coquitlam or Port Moody and occasionally at one another’s homes. They use public transport or lifts from family members when travelling between their homes. They also exchange recommendations for books and music.
Seraphim is usually the more animated of the two in conversation, teasing Yoneno and receiving quieter remarks in response. Their friendship is not confined to organised events; they are also comfortable spending an afternoon talking or pursuing separate activities in one another’s company. Both initiate outings.
School friends
Megan Cartwright has known Seraphim since elementary school, and they became close around 2012. Both attend Gleneagle, where they see one another regularly. Megan sometimes accompanies Seraphim to live performances, although their musical preferences differ, and the two frequently compare schoolwork or meet after classes.
Callum Mercer became acquainted with Seraphim during their first year at Gleneagle. They share classes and often speak during breaks. They sometimes visit an arcade with other school friends, although most of their contact is connected to school.
Paper Observatory
Seraphim knows Katherin Konstanz through overlapping musical and ena acquaintances. They share an interest in music and occasionally participate in informal demonstrations or outings. Seraphim is comfortable disagreeing with Konstanz and is frequently receptive to unusual suggestions that sound enjoyable.
She and Chelsea Vail exchange recordings, discuss arrangements, and rehearse guitar parts together. Their friendship extends beyond the band, although music is their principal shared activity. Vail ordinarily sings the band’s lead parts, while Seraphim contributes backing and occasional lead vocals.
Seraphim is on friendly terms with Emma Mayfield, whom she knows principally through band rehearsals, performances, and group outings. Their friendship is less longstanding than her relationships with Sana or Megan.
Other acquaintances
Seraphim occasionally spends time with Hanae Wakami through mutual friends and informal ena activities. They are comfortable with one another but do not maintain a particularly close friendship independently of the wider group.
She is also acquainted with Evelyn Socha of Seattle, with whom she communicates intermittently. Their contact is friendly but irregular.
Music and recreation
Guitar and concerts
Seraphim spends considerable time practising electric guitar, listening to new recordings, and attending concerts. She enjoys hardcore punk, metalcore, and drum and bass, especially Turnstile, Knocked Loose, and Pendulum. Her listening also includes alternative rock, shoegaze, and dream pop, particularly Slowdive and Beach House.
At concerts, she favours prominent bass and percussion and enjoys moshing. She sometimes travels to performances with friends, making practical arrangements to return home when events end late. Concert shirts, tickets, and flyers are among the items she brings home from outings.
Firearms and ballistics
Seraphim is interested in firearm design, handling, and history. She reads publications on firearms and ammunition and participates in supervised target shooting when the opportunity arises.
She is also interested in practical ballistics, particularly the effects of impact, penetration, and explosive discharge. She enjoys comparing observed results from controlled tests with descriptions she has encountered in reading.
Reading and games
Seraphim enjoys supernatural horror fiction and comics, particularly the work of Shirley Jackson and Junji Ito. She occasionally becomes absorbed in a novel or manga volume and loses track of other obligations.
She also plays table tennis and arcade games with friends, mainly as casual recreation. Social outings frequently involve cafés, casual meals, or visits to friends’ homes.
Clothing and domestic habits
Seraphim’s everyday wardrobe consists principally of jeans, loose tops, trainers, and jackets. She frequently wears band shirts and other clothing purchased at concerts. Comfort and personal preference matter more to her than carefully coordinated outfits.
She usually keeps her honey-blonde hair around shoulder length, sometimes tying it back while playing guitar or undertaking practical activities. She does not spend much time styling it.
Her guitar and associated equipment are kept in usable condition, while clothes, school materials, books, and incidental possessions often accumulate around her room. She retains tickets and flyers from concerts without organising them into a formal collection. She occasionally earns small amounts of money through casual jobs for family acquaintances but does not have regular employment. She has considered further education or training after secondary school without committing to a particular profession.
Preferences
Likes: Loud music with prominent bass and percussion; energetic concert audiences; spicy noodle dishes; savoury pastries; cherry cola; supernatural horror; spontaneous outings; and live music.
Dislikes: The texture of cooked mushrooms; sour cream; marzipan; comedy based on prolonged second-hand embarrassment; and overnight camping. She enjoys some outdoor day trips but generally prefers returning home to sleeping in a tent.
