"A ghoul, as I'm sure you know, is a disgusting creature who opens graves and feeds on corpses."
-— Baron Sardonicus, Mr. Sardonicus
Humans who consume the blood of Nosferatu gain the same benefits as other ghouls: incredible strength, increased vitality, and a reprieve from aging. Along with these gifts, however, they also receive a foul taste of Nosferatu's curse. After a thrall has taken the third dose of his regnant's blood, he begins to take on subtle changes that render him unattractive and unsightly. It's only a slight transformation, but mortals who deal with Nosferatu ghouls always suspect that something is not quite right with them. Acne, greasy hair, weight problems, slouching gaits and body odor are just part of the problem: there's an unnatural taint that goes deeper than pockmarked flesh...
—Vampire: The Masquerade - Clanbook: Nosferatu (Revised)
Carrion-reek breath and a seeking tongue that can taste decay from a mile away. Grim feasts in mausoleums and mass graves, serenaded with their gibbering language. A marriage of cadavers and carcass eaters. Corpses teach ghouls what it is to be patient. Ghouls teach corpses what it is to be wanted. Round and round.
They are the trash compactors of the secret world. Ghouls, as a general thing, have no higher agenda. They are what they are, following the scent of rotten flesh, digging up the dead for their morbid repast. Other supernaturals tend to treat them with disgust. Humans instinctively avoid those burial spots that become ghoul feeding grounds. The ghouls fill their gross niche.
