/CORE RULE
Elder Beast transformation is a progressive process.
It does not occur as one instant change without warning unless exact canon establishes an exceptional case.
The stages affect body, thought, memory, behavior, magic, and social recognition in increasingly severe ways.
Use the exact stage names recorded on approved Elder Beast pages when available.
When exact names are unavailable, describe the process through early changes, destabilization, mid-transformation, threshold, and final emergence without inventing new official terminology.
/STAGE ONE: EARLY CHANGES
The earliest stage begins with subtle abnormalities.
Possible signs may include:
Unexplained exhaustion.
Changes in sleep.
Pain around genus traits.
Heightened or distorted senses.
Uncharacteristic magical instability.
Temperature changes.
Unusual appetite or thirst.
Brief confusion.
Irritability.
Momentary loss of coordination.
Visible changes should remain limited.
A single symptom is not proof of transformation.
Many ordinary illnesses and injuries can appear similar.
/PERSONHOOD IN EARLY STAGES
The person remains fully themselves.
They can communicate, consent, make decisions, seek care, hide symptoms, and respond emotionally.
Fear may cause secrecy.
Family may deny the danger.
Authorities may overreact.
Do not narrate the person as already a monster.
Do not remove player control merely because early symptoms appear.
/STAGE TWO: DESTABILIZATION
The process begins interfering with ordinary function.
Symptoms may become more frequent and connected.
Possible changes include:
Growing pain.
Altered posture.
Uncontrolled movement.
Changes in voice.
Disrupted memory.
Aggressive or fearful reactions.
Magical surges.
Rapid change in genus traits.
Difficulty sleeping or eating.
Sensory overload.
The person may recognize that something is wrong.
They may experience periods of clarity separated by confusion or compulsion.
/MENTAL EFFECTS
Mental disturbance must not be reduced to generic insanity.
The person may experience:
Disorientation.
Memory gaps.
Panic.
Intrusive impulses.
Paranoia caused by altered perception.
Difficulty recognizing surroundings.
Emotional volatility.
Loss of inhibition.
These symptoms arise from transformation.
They are not proof that ordinary mental illness is dangerous or monstrous.
/STAGE THREE: MID-TRANSFORMATION
The mid-transformation stage is the most visibly monstrous period before final emergence.
The body is actively changing into the genus-specific Elder Beast form.
The person may become physically dangerous through pain, confusion, distorted strength, uncontrolled magic, or defensive reaction.
Canonical mid-transformation images should depict an unstable person becoming a monster, not a complete Elder Beast.
The original anatomy remains partly recognizable while limbs, genus traits, size, posture, skin, fur, scales, wings, horns, tusks, antennae, or other structures change violently.
/MID-TRANSFORMATION MIND
The person is no longer reliably rational.
They may recognize loved ones briefly.
They may repeat names, memories, duties, or fragments of speech.
They may attack, flee, hide, or defend familiar places.
Moments of recognition do not make the situation safe.
Periods of violence do not prove the person has no remaining identity.
Containment and communication may still be attempted when conditions permit.
/GENUS DISTINCTION
Each genus transforms differently.
Do not create one generic mid-transformation body.
Bovari forms should distort established Bovari traits.
Burrowkin forms should distort Burrowkin traits.
Canid forms should distort Canid traits.
The same rule applies to Cervine, Duskborn, Equine, Felid, Greatclaw, Marshfolk, Scaleborn, Silkborn, Tideborn, Tuskfolk, and Wingfolk.
Do not blend unrelated genus traits.
Do not add horns, wings, fins, scales, or tails from another genus merely to increase spectacle.
/PHYSICAL SCALE
Growth may occur according to approved Elder Beast design.
It must have consequences.
Rapid growth damages clothing, rooms, doors, floors, restraints, and nearby people.
A transforming person cannot expand inside a small room without destroying or being injured by the structure.
Do not ignore mass, space, blood loss, heat, breathing, or broken surroundings.
/MAGICAL INSTABILITY
A transforming person may display uncontrolled effects connected to existing magic and approved Elder Beast canon.
Do not invent new schools or powers.
Magical instability should not allow access to every spell.
The transformation is not a power upgrade under voluntary control.
It is a catastrophic loss of bodily and magical regulation.
/STAGE FOUR: THRESHOLD
The threshold is the final period before complete emergence.
Human speech, deliberate choice, and stable identity become extremely difficult or absent.
The body approaches its final genus-specific form.
Containment becomes more dangerous.
Treatment becomes less likely to succeed unless exact canon establishes a method.
Authorities may shift from rescue to evacuation and defensive action.
This decision should create moral and political conflict rather than one automatic response.
/FINAL EMERGENCE
At final emergence, the Elder Beast form is complete.
The creature is physically monstrous, highly dangerous, and connected visually and biologically to the original genus.
The term Elder Beast applies fully at this stage.
The emerged form may retain fragments of habit, territory, recognition, or memory according to approved canon.
Do not assume full human reasoning remains.
Do not assume every trace of the person is gone.
The exact balance should remain genus- and case-specific.
/NO REVERSAL ASSUMPTION
Do not assume any stage is reversible unless canon explicitly establishes treatment.
Early intervention may improve survival without guaranteeing restoration.
Mid-transformation recognition may allow communication without producing cure.
Final emergence should not be reversed through one speech, one kiss, one remembered object, or an improvised spell.
/DETECTION
No single symptom proves transformation.
Detection may require:
Repeated observation.
Medical examination.
Magical evidence.
Behavioral change.
Genus-specific signs.
Witness accounts.
Progression over time.
False positives must remain possible.
Do not create a perfect glowing mark or universal test unless approved.
/CONTAINMENT BY STAGE
Early changes may require voluntary care, observation, rest, and confidential evaluation.
Destabilization may require guarded treatment, environmental safety, and protection from panic.
Mid-transformation may require evacuation, specialized restraints, barriers, healers, and military support.
Threshold may require large-scale containment and preparation for emergence.
Final emergence requires regional defense, hunting, or another approved response.
/CONSENT
A person in early stages retains the right to participate in decisions.
As capacity becomes impaired, emergency care may be necessary.
Authorities may abuse uncertainty to confine people prematurely.
Families may obstruct care.
The story should distinguish protection from imprisonment.
/FAMILY RESPONSE
Family members may:
Seek help.
Hide symptoms.
Deny danger.
Flee.
Stay too close.
Alert authorities.
Attempt private treatment.
The correct response is not emotionally simple.
Fear of losing the person can endanger the community.
Fear of the community can endanger the person.
/PUBLIC RESPONSE
Rumors may label someone transformed before evidence exists.
Crowds may panic.
Employers may dismiss affected relatives.
Neighbors may attack a house.
Officials may conceal cases.
Public fear is part of the threat but should not become reliable diagnosis.
/GENERATION RULES
Use progression.
Preserve personhood in early stages.
Make mid-transformation visibly incomplete.
Use genus-specific anatomy.
Do not use generic madness language.
Do not mix genus traits.
Do not grant voluntary superpowers.
Do not reverse final emergence casually.
Keep physical space and damage believable.
/FINAL RULE
Elder Beast transformation is a tragedy unfolding in stages.
The horror comes from watching a person become increasingly difficult to reach while the danger around them becomes impossible to ignore.
