Spring-Heeled Jack

Origins/Myth:

Not much info is confirmed about this long standing London dwelling urban legend. “He” is known to be a figure of unnatural agility, capable of clearing walls and rooftops with ease. Witnesses describe a tall, gaunt silhouette clad in tight, oilskin-like garments, eyes burning with a crimson glow. The most disturbing detail—an exhalation of blue-white flame, as if the lungs themselves were a furnace.

Field Report:

Jack appears to favor isolation—attacks occur on dimly lit lanes, targeting lone women. His approach is sudden, often preceded by a metallic clatter, perhaps from clawed gauntlets. Victims report a grip “cold and clammy,” suggesting either armor or something… not of flesh. Again most information isn’t verifiable, and no field agents have confirmed any of these, with only encounters being non combative and from a distance. There has not been an official sighting verified by the Society since a Boxing Day, 1898 in London, which as of now is the only locale this being has been spotted in. Below is the Official A.P.I.S Field Report.

Entity/Creature Classification :

Type : Paranormal Predator / Urban Legend Entity
Threat Level : High
- Justification:
  - Physical harm potential (claws, flame emission)
  - Psychological impact (panic, hysteria)
  - Elusiveness (extreme agility, nocturnal activity)
  - Unknown origin and motives
Known Regions : All sightings, call ins and encounters both with official APIS Agents, and with the civilian populace have all been in London, but assumedly this being can travel wherever it would like to. APIS agents have spent 2 generations guarding the British mainland to be sure nothing that matches the description of “Jack” has left the isles. Our longest serving agents are on this watch, some of which are generational members of the Society.

Signs of Presence / On Site Indicators :

Auditory Clues
- Metallic scraping or clatter (possibly from clawed gauntlets).
- Sudden thuds or echoing impacts on rooftops—indicative of high leaps.
Visual Indicators
- Glimpses of a tall, thin silhouette in tight, dark clothing.
- Glowing red eyes in low light.
- Brief flashes of blue-white flame or sparks in the dark.
Environmental Disturbances
- Unexplained scorch marks on walls or cobblestones.
- Deep gouges or claw marks on wooden doors or fences.
- Reports of livestock or pets behaving erratically (fear response).
Behavioral Pattern
- Prefers isolated streets and alleys after dusk.
- Targets lone individuals, especially women.

Preventative Measures :

Avoidance:
- Do not travel alone at night; stay in well-lit, populated areas.
- Secure upper windows and rooftops—Jack favors vertical approaches.
Defensive Gear:
- Heavy cloak or leather garments to mitigate claw damage.
- Carry a lantern or magnesium flare—bright light may disrupt his theatrics.
Psychological Preparedness:
- Maintain composure; panic amplifies vulnerability.
- If confronted, create noise—whistles, bells—to attract attention.
Observation Protocol:
- If signs are detected, retreat to a secure location and record details from safety.
- Do not attempt pursuit; his mobility far exceeds human capability.

Capabilities :

Locomotion: Leaps exceeding nine feet; trajectory suggests spring-assisted limbs or musculature beyond human norms.
Offense: Razor-like claws; flame emission capable of singeing fabric and inducing panic.
Psychological Impact: Victims exhibit hysteria and lingering dread—Jack thrives on terror.

Strategy (If Encountered) :

Maintain Distance
- Jack’s primary advantage is mobility and surprise. Do not close in—his leaps allow rapid repositioning and escape.
Disrupt Visibility
- Use bright light sources (lanterns, flares, magnesium strips). His theatrics rely on darkness; sudden illumination may startle or deter him.
Create Noise
- Whistles, bells, or even firearm discharge (if available) can attract attention and break his psychological dominance. Jack thrives on isolation and fear.
Seek Higher Ground or Shelter
- While Jack can leap, enclosed spaces with narrow entry points limit his maneuverability. Barricade doors and windows quickly.

Speculation :

Is this a singular entity or a phenomenon born of mass hysteria? The precision of his strikes and theatricality hint at intelligence—perhaps even a cruel sense of humor. Some whisper of a wager among the gentry; others, of a demon loosed upon London’s streets. Society leadership isn’t convinced either way, so strictest adherence to the code and procedures advised until more info has come to light. As always, keep it contact with your field officer, district wardens and all leadership when you believe you’ve made contact with an official Society deemed anomaly or entity. Happy Holidays, and New Year Agent. Eyes up, darkness requires eternal vigilance.
