The Sin-Eater

The Sin-Eater is an internet urban legend much like the likes of Slenderman or The Rake.

Lore
According to the original story of the Sin-Eater, it is a monster that was summoned by all the people in the world that have been wronged, such as people who have been scammed or even murder victims. Whether it is actually them (or their spirits) or if they are simply manifestations is unknown. What the Sin-Eater itself does changes depending on the story, though in most it devours the "sinner", hence its name.
