The blessed damned stalks the world, pity the Ghoul

The world is truly damned and death is all around. The divine mechanism is faulty but balance is still its sole purpose. Thus, the Ghouls are the most common type of sentient Resurrected, a blessing and a curse on the world. They are the altar cleaners and sin eaters, born to purify the dead. When man drops dead and his corpse is devoured, it will not rise again. They are the cycle's response to the restless dead and thus their suffering is as eternal as death itself. They are cursed with insatiable hunger for the flesh of man and food turns to dust in their mouths.

The Ghoul looks emaciated. From far, one may mistake them for an opium addict, helplessly gaunt. Their hollow, deep-set eyes don't help this, dark black sclera and pupils with golden irises. The combination of agelessness and endless starvation means that they are often withdrawn and moody; their diet of human flesh means that most people will never get a chance to find that out. On their blue-grey skin, most ghouls are heavily tattooed, lines and lines of names spanning their limbs and torso. It is a superstition and also penance, the Ghouls keep records of everyone they eat. It is in the act of eating where they especially horrify, their mouths open slightly too large and their teeth slightly too sharp. Most ghouls keep the bottoms of their faces covered with veils or muzzles to give some mild reassurance to the general public. They are viewed with suspicion and distrust, a necessary evil in society. They are the alternative that smaller villages turn to, as Grave Priests don't often travel to the most remote corners of Liurza.

No one likes seeing a Ghoul smile

Stories warn of Ghouls with kindly, plump faces and pink, unblemished skin.  Consider how many people would have to die to fatten a Ghoul to that extent, how much blood one has to drink to revitalised dead skin. The Unmarked are unrepentant, revelling in their status as a predator rather than scavenger. It is perhaps ironic that the Ghouls that most resemble a human are the most monstrous.

(The Ghouls is perhaps one of the more difficult races to adapt to 5th Edition DnD. You will have to use the Dhampir from the Gothic Lineages Unearthed Arcana but with some modifications. Remove Darkvision and Spider Climb. Then, the Ghoul gets Relentless Endurance [Half-Orc trait], Resistance to Necrotic Damage, as well as not needing to eat apart from one meal of human flesh a day.)
