Designed for one purpose only -- to hunt down and destroy all enemy life forms But man's greatest weapon has continued to evolve without any human guidance, and now it has devised a new mission: To understand life, its purpose, & the human soul. 
These proto positronic lifeforms have continued to evolve in the cold depths of space. Each generation sending out its strongest members to attack colony ships & the enemies of mankind.Each time they report back to their maker units & more are sent out with express purpose of destruction. 
 Then one day it simply stopped. The creatures took on a new face the face of their creators both angels & demons to them. They raided ships took prisoners & began to put them through a series of experiments each more bizarre then the next.
  The creatures are becoming increasing alien as time goes on. Their behavior is that of a naturalist looking through the population of mankind for something. No one is sure what. 
Structures left behind by these creatures are new, shiny, & lethally full of traps. They seem designed exclusively for mankind & his allies. They often have a combination of physical, energy based, & many other types of obstacles for those who find them.
The creatures themselves are rarely encountered but those who do have been questioned at length patiently, precisely, & then brain scanned. Some are destroyed & some let go. 
Those scanned & let go are sometimes implanted with a tracing dye within their veins & others given a micro dot tracing unit in areas of certain organs. 
These creatures attack with a mouth full of fully charged auto injectors full of a lethal cocktail of poisons. The victim must make a save vs death or be consumed by the lethal cocktail as it takes his body apart bit by cellular bit. 
The most feared attack however comes from the sonic baffles built into the throat of the creatures. They attack with a series of sonic screams capable of shattering metal, setting flesh on fire, & exploding bone. The attacks are at 1d8 points of damage, the metal ones are at 1d10 however a simple shield belt counter act these effects for a time. 
   The Screamers have a weakness. They can't pass up an opportunity for a game of chance. Many negotiations have come about over a simple game of chance in which they view as another opportunity to study the human or humanoid soul. A charisma roll allows one to charm them into a game & move them to the higher realms of reason. It should be remembered these beings are completely alien to the humanoid mind & approached with caution. They won't be found in your local gambling hall but in the places where you least expect them.
