Entity Classification

Aggressiveness 1/5 The entity does not seek out wanderers and will only cause harm if disturbed.
Frequency 5/5 The entity is abundant in levels of the backrooms with large quantities of electrical devices.
Intelligence 1/5 Voltaic Urchins are not capable of advanced decision making nor intelligent thought.
Pritoria Index 2.333/5 Voltaic Urchins are a minimal threat to wanderers, but can become hazardous if proper precautions are not taken.

Voltaic Urchins, likened to the aquatic Urchins of baseline reality in appearance, are unorthodox clusters of colonial microorganisms that leech electricity from the infinite backrooms power grid. Voltaic urchins generally take the form of spiny, amorphous-bodied spheroids stuck to surfaces that can vary greatly in size, from microscopic to meters in diameter.


Voltaic Urchins are generally stationary creatures, preferring to nestle themselves into tight niches such as corners or air vents for protection. If incapable due to their current environment, or if a threat is detected, Voltaic Urchins will detach themselves from the surface they are clinging to and attempt to flee. They will achieve this by splitting into numerous smaller colonies of microbes that are light enough to float in the air. In this state the smaller urchin colonies are extremely dangerous as inhalation of the organisms will lead to severe lesions within the lungs of the victim.

Along with serious lesioning of lung, eye, and skin tissue, victims of Voltaic Urchin disruptions often suffer electrical burns as when disturbed previously stored electricity is violently discharged. These discharges have been recorded to be as high as thirty million volts, and are dictated by the overall size and stored energy within the original Voltaic Urchin colony prior to it being split.

Voltaic Urchins have been observed to seek out ventilation systems to reproduce, shedding smaller urchin colonies to be taken away and spread throughout the Backrooms by air currents. This generally occurs every four to six months. Along with this reproductive process, Voltaic Urchins have shown migratory behaviors, preferring to flock to the Electrical Station to spread the smaller colonies to mature. How the entity is able to travel to the Electrical Station regularly from varying locations is unclear, however it is theorized that the ventilation systems of the Backrooms are interconnected in some way, most likely through means that only microbial life could actively utilize.


Voltaic Urchin colonies are hard to study due to their volatility and lack of sufficient equipment, however it is known that the microscopic creatures work as one large colonial body, taking different roles to ensure the survival of the collective creature. Examination of dead specimens neutralized with unprovocative means such as noxious gasses have shown a fibrous interior which is theorized to be for integrity without sacrificing the creature's flexibility or weight. Since most biological functions occur on a microscopic basis within the interior of the creature observation of the colony ecosystem is all but impossible with current means.


The first modern-day documentation of Voltaic Urchins was an investigation into mysterious plumes of black suspended material in the air seeping from vents across the Backrooms, eventually leading to proper documentation of the entity.

Survival Guide

Voltaic Urchins prefer to reside in tight areas, it is advised to avoid these spaces as a precautionary measure.

Voltaic Urchins are present in the ventilation systems, during their reproduction process clouds of miniscule colonies may be expelled from the ducts which pose a danger to wanderers as aforementioned. Listen for sounds of a partially or completely obstructed air passage if you suspect one may be inside of a vent or similar air system in your immediate surroundings before passing.

Do not make physical contact with the colony as it will perceive you as a threat, instead divert your course if applicable. If avoidance is not an option move by extremely slowly to avoid disturbing it.

Wear protective equipment such as face masks and cover as much of your body as possible when traversing highly ventilated or highly electrical areas.
