Revenant

The Revenant are a mysterious race of beings who appear to be the reanimated corpses of ancient humans, kept alive via advanced life support and temporal technology. Despite very few encounters with these beings, to the point many doubt their existence, they are considered be the most feared enemy race known to The Crucible.

Theories Of Origins
Not much is known about The Revenant, as they are rarely encountered, and those who do encounter them rarely survive. What information is available is mostly speculation on the parts of "experts" who attempt to study these strange entities. And most theories are hotly debated to this day.

What many seem to agree upon, however, is that they appear to be humanoid in appearance, with an obvious human skull being the noteworthy and consistent detail among many survivors. Which has prompted some to speculate if they aren't, in fact, humans. It certainly doesn't seem far fetched as the few survivors of these creatures report seeing the skeletal visage shift to that of a more fleshy, yet absolutely tortured, human face on occasion before being reverted to the twisted image of bone and technology.

Others believe the Revenant are yet another remnant of Mankind's Final War, a ghastly weapon which now roams the depths of dark space under the impression that the war it was made for is still ongoing.

Whatever theory happens to be true is redundant however, as all greatly fear these nightmarish creatures.

Known Encounters
Much like the Boogeyman from ancient myth, The Revenant are sometimes written off as nothing but superstition. A horror tale to scare new recruits. However, there have been a few of accounts which may or may not prove they are very much real, and just as deadly as the legends say. Here are a collection of known encounters with The Revenant.
 * The Idolan-Mor Incident: Reknowned Seeker and Navigator Idolan-Mor recorded an instance while exploring N-Space where he encountered a Revenant vessel. He says the ship paid him no attention and proceeded to access an, at the time, locked off pathway within N-Space before sealing it behind them. This encounter, for all intents and purposes, is considered genuine due to the confirmed sensor readings taken by the ship and has continued to spur on the idea that The Revenant are, in fact, ancient humans.
 * The Janus Tear Incident: The Crucible of Janus Tear was suddenly, and inexplicably, wiped out by an unknown force with no survivors found. Not much remains of The Crucible to tell the story aside from a fragment of an audio log from a Seeker which many believe says: "They came through the walls. Ivory grins of death. They slaughtered us all."
