Blight
The Blight is a general term for describing hazardous subterranean, surface, atmospheric, and orbital phenomena of Talos-II. Such phenomena can be divided into two categories: (1) Active Blight and (2) Static Blight, of which Static Blight is often regarded as the residual remains left when an Active Blight episode has subsided.
Classical cases of Active Blight, such as Blightfloods commonly seen on the surface or Blight Tides in bodies of water, tend to exhibit optical properties unique to the Blight often seen as fluorescent displays of strange colors. The phenomenon of Active Blight can inflict dissociative and/or inversive destruction of variable rates to any object it contacts or swallows. In other words, Active Blight can deprive matter and/or time from the physical space it manifests in. This destruction can either be rapid and absolute or slow and slight. After a period of time (the shortest duration on record is 217 ms while the longest is over 149 years), Active Blight will slowly decay into Static Blight that resembles a layer of fluid asphalt covering the remains of the destruction wrought by Active Blight.
The Blight exerts unique effects on sentient lifeforms. Survivors of Blight events often report auditory and/or visual hallucinations, sudden episodes of stress, or other mental conditions even in the complete absence of Blight-induced brain injury (BLIBI). NOTE: Almost all cases of BLIBI fail to survive.
Having gathered more than a century's worth of samples and data, we can now confirm Active Blight appears in places where Depth readings hit a positive number. Probability distribution of Active Blight incidence is typically a bell-shaped curve against an x-axis of Depth readings from 0 to 1.
