The Revenant is one of the undead, a once-living deceased human without a soul, doomed to kill and feed on the living for its own sustenance.
Etymology
The term revenant can be used to refer to any form of the Undead, whether it is a vampire, a ghost, or a zombie. The word revenant comes from the French and Latin verb revenir, which means to return. Therefore, the Revenant is a once-living human that has returned from the dead.
Description/Morphology
Having recently arisen from the grave, the Revenant is usually a corpse in an advanced state of decay, but still somewhat recognizable to those it knew in life. The creature has sunken eyes, which glow a fiery red in the darkness. It has rotten teeth and jagged fingernails. Large portions of flesh may be missing, exposing the creatures bones and innards. The skin tends to hang from the flesh in ragged strips, while maggots and worms infest the exposed flesh, as well as the eye sockets and other bodily orifices. The Revenant reeks of corruption and rotting flesh, and the creature can be detected from several yards away just by its smell alone. The Revenant is usually wearing its burial shroud or whatever clothes it was wearing when the individual was interred, now it tatters from clawing its way out of the grave. Behavior
The Revenant is dangerously obsessed with gaining its vengeance on those who wronged it while it was still living or caused the creatures death. Although there have been some accounts of this creature being benevolent and protective of its loved ones, seeking only to prove its innocence of the crime of which it was wrongfully accused, or to complete some pressingly important task. However, this is extremely rare in lore and legend.
The Revenant is single-minded and relentless in its pursuit of the one that wronged, betrayed, or even murdered the Revenant while it was alive. Rest assured, this creature will hunt down and dispense the justice that it feels the wrongdoer deserves, which usually means killing the unfortunate (but well-deserving) individual. Once in a great while, the Revenant will take up its own case, investigating the circumstances surrounding its death, and instigating a retrial until it is proven innocent or the killer is given justice. Again, this is extremely rare. Usually, the Revenant doesnt interact with the living. If cornered, it will fight to the death. It knows that, wherever the traitor hides, it will find them eventually and take the revenge that it craves. At this point, the Revenant will return to its grave, never to rise again.
