Homo Sapiens Necrotii

Homo sapiens necrotii (s. necrotus) is the official scientific classification of reanimated deceased individuals infected with Retroviridae Alphavirus Necrotosis. They are most commonly referred to as necros, but are also known as zombies, zeds, and ghouls.

While there are a number of different breeds with unique characteristics, they are all defined by their aberrant desire to kill and feed on those remaining living survivors, which they vastly outnumber.

Biology

A human infected with the Omega virus nearly always dies and reanimates as a necro. This process is referred to as "turning" or "waking up." While they, with obvious disparities, still resemble humans, their DNA has been altered drastically, transforming necros into base predatory animals with increased aggression and a loss of higher brain functions (including speech, conscience, and self-preservation).

Basic Faculties

Functionality retain some biological faculties

sight, hearing, smell, vocalization

dependent upon rate of decay or injury

heightened ability to detect sound waves and thermal signatures

cause as yet unknown retain muscle memory

generally coordinated

can command operable muscle groups independently Basic Imperatives compelled by a basic imperative to feed

ingestion of blood sustains central nervous system

cause as yet unknown

grow lethargic when undernourished

Self-Preservation present with mRNA decay

disrupts the production of Na

sodium channel protein

facilitates amplification of nociceptive neurons

inhibits or arrests pain sensation

Cellular Regeneration

Extermination neutralization requires termination of brain function Hive Mind

Hive Mind is an aspect or condition whereby necros in close proximity to one another operate under a collective consciousness. This occurs most often among necros occupying a POINT, and much the same way as bees or ants, they are driven to seek out prey as a conglomeration, often without observable communication. Because of this relation to other colony species, this phenomenon is referred to as "swarming" or "hording." Understanding of how this communications occurs is minimal, though many believe pheromones are involved.

Necrotic Emissions For reasons also unknown, necros emit an electromagnetic field much stronger than an average human. This emission is composed of Terahertz radiation which possesses a unique alpha pattern signature.

referred to as Necrotic Emissions (also the Buzz, argot) Aural Necrosis Phenomenon

also Dead Silence, argot

mutes external environmental aural effects

Nest characteristic

Emission Sickness

referred to as EMS (also Buzz Flu, argot, also Cider Sickness, pejorative)

symptoms include fatigue, nausea, disorientation, cardiac arrhythmia

cause as yet unknown
