Inferrectus

A member of the Elder Race contaminated by an experimental strain of the Inferus plague. The creature was not the only one of it's kind, yet it possessed an encyclopedic knowledge of the Elder Race's history as well as a psychic connection to the Inferus hive mind. The Ancients preserved it in a stasis chamber that was left for millions of years until it was accidentally unearthed by human soldiers during wartime. Not to be confused with Vates.

Second Inferus Wave and the Elder Race
The entire Ancient civilization was weakened by the Second Inferus Wave and would eventually meet its end in the war with the Elder Race. A bioweapon program was created to attempt to destroy the invaders, and mutant strains of the Inferus infection was tested on Elder Race captives. Thus the Inferrectus was born, an abomination of the Inferus flesh and the plant-like matter composing the Elder Race. When it was discovered the Inferrectus had an inherent psychic link with the Inferus hive mind, the Ancients kept it to study. However, it's mental merger gave something unidentifiable to the Inferus, fundamentally changing them. The Ancients sealed the Inferrectus in a deep facility in stasis and abandoned it there. It continued to communicate with the Inferus and influence their growth.

Mankind Digging up Demons
During a war between the Union of Planets and the New Earth movement, the New Earth soldiers occupied a strategic point on an uninhabited, yet mostly terraformed planet in UoP space. While occupying this territory, engineers discovered an underground facility extending for miles beneath the planet's surface. Xenoarchaeologists identified the structures as belonging to the same forerunner race which had been noted across the entire galaxy. This was in an early stage of mankind understanding the existence of their predecessors. Their presence awoke the Inferrectus, who began to attempt to communicate with the humans. After establishing a means of communication, the humans interrogated it, eager to gain more of it's ancient, primordial knowledge of the universe. The Inferrectus knew much, as a ranking Elder Race leader and with connections to the collective Inferus mind. The Inferrectus was actually manipulating the humans, trading knowledge for knowledge of the current state of the universe, and feeding this knowledge back to the imprisoned Inferus hive mind. The record of Doctor Allison Shaw is famous across the galaxy for the information it contains about the ancient galaxy and what transpired. The Inferrectus does not directly inform the humans what happened to the Ancients, only stating that "I happened." This refers to both the Elder Race and Inferus calamities that brought down the Ancient society. Much of what the Tog'Ratha believe comes from such sources as the Inferrectus.
