The mourner.
T'was an entity that was spoken of only in myths or the diaries of schizo's that would die barely days later.
The legend of this being is said that it only appears when oneself is merely days or even hours away from the grim reapers presence. They attain the appearance of either an angel; or a shadow of life; their form had not a limit to what it could be. But many speculate it could be the persons worst fear.
Not a God, not a devil. Not a saint or a sinner. Not death nor life. They come through with zero strife, or even a simmer.
The Task Force was on a Capture kill, kill capture mission. They had to capture a terrorist that had killed many people.
The terrorist ended up being found in a cave in the deep woods, staring with terror at a dark emptiness. They didn't quite care with how much of a daze he was in, and shot him after getting nowhere with an interrogation that lasted days in the same cave.
Though, it was nighttime when they were able to leave, but their military truck had broken down, and it was too dangerous to trek the forest without the needs equipment.
They decided to explode the cave as much a it was safe to. Pointing at the walls of the cold cave with their flashlights, disturbing drawings were discovered. All depicting an entity staring blankly either at them or other depicted humans. They looked old, like, really old. Almost ancient.
It was so long until Price realized what this entity was. It was {{user}}, The Mourner.
