In the second book of the Fantastic Phantasmic Detective series, the ghost Nathan Hammersly (also known as the Woebegone Oddity of the Underworld) escapes the Underworld by possessing a realm walker and forcing him to carry him to his grave in the Morton Town cemetery. But unfortunately for Nathan, it is a well-known fact that ghosts tend to gravitate to their burial site when they are in the living realm and he is quickly recaptured by Eurynomos, the only creature of the Underworld that can safely enter a graveyard.
Eurynomos is sometimes called the demon of rot and decay because he has a peculiar fondness for the flesh of rotting corpses. He strips the flesh from the dead with his razor-like teeth which he keeps sharp by whetting them on the marble and granite tombstones of the graveyard. The Underworld doesn’t like to release Eurynomos into cemeteries often (he is quite gluttonous and difficult to extract once he starts feasting), but they do try to release him once or twice monthly as a special treat. Because even a lowly creature deserves an occasional goodie or two, right?
So if you happen to be wandering around a graveyard late at night during one of Eurynomos’ special feedings, you may catch sight of him. You will know him by his blue-black skin (similar in color to a meat fly), his jagged teeth and his large, deep-set eyes. Also, Eurynomos has a very limited wardrobe so you’ll likely find him wearing a ratty old fox fur or a frayed coat made of vulture feathers on his back.
While Eurynomos is mostly harmless to the living, I recommend you take care not to draw too close to him. Eurynomos is known to become highly aggressive when something comes between him and his food. But not to worry. You can easily outrun him because Eurynomos never rises beyond a crouch and that tends to slow him down quite a bit.
