This is the origin story of vampires, werewolves and zombies which apparently all came from Mesopotamia and the accounts of ghouls being able to turn into hyenas at will and the song origin of species from Lestat by Sir Elton John.

There is a reference to Lilith here and if you look her up, you'll see she is the mother of monsters and the description of the ghoul is 1 of the references.

Enjoy

Indulge me if you will my friends
For I've a tale to spin
Of all the vampires on this earth
Of my unholy kin
I am the oldest one by far
Marius is my name
When I was born it was the time
The Roman empire reigned

When he was born it was the time
the Roman empire reigned

Unlike you mortals as you age
The weaker you become
For us is quite the opposite
The years just make us strong

But like you we feel pain and loss
And suffer heartbreak too
We ponder our existence
In the same way as you do

We ponder our existence
In the same way as you do

In the myth of your creation
There's poor Adam and sweet Eve
Temptation and you gave us a pair of serpents as parents named Lilith and Satan
And there was the devil's apple tree

We have Enkil and Akasha
An Mesopotanian king and queen
The mother and the father
Of we beastly, bloody and nocturnal fiends

The mother and the father
Of we beastly, bloody and nocturnal fiends

Marius tell us more
Marius tell us more
Tell us more, tell us more
Marius, tell us more

14 thousand years ago before the pyramids were built
Enkil and Akasha ruled with wise benevolence
A splendor of Mesopotanian life was prosperous and good
But in their kingdom enemies were present
And so it happened that a demon in the form of a large Hyena with owl feet and a serpent tail came in to the town
And took a liking to the home of some unfortunate
Who pleaded to wise Enkil for his council and advise
Before his home this demon beast desecrated
The king in all the faith decided to engage the beastly ghoul
In hopes his evil ways by chance he might dissuade
The queen would not allow her king to face this deed alone
And in her choice the hand of fate was played

The hellhound tossed the furniture, snaped, roared and laughed a hellish laughter, malevolence abounded
And while they pleaded to be heard they found themselves surrounded
Assassins of the enemy, their collective knifes gleaming
Hacked and stabbed the royal pair and the creature itself and left the 3 bodies bleeding

As they lay dying on the ground the poltergeist blood from the creature did spill
And entered in the wounds of their illustrious monarchy
Their reanimated bodies bore an terrifying glow
Alive to them but dead to you and me
The demon in their veins, they gained a supernatural power
But one that left them sorely lacking human traits
No longer to partake of food and drink or bear a child
Their hunger only flesh and blood could satiate

They could not face the blazing sun
It's magnficence was blinding and burning
But the power of gods and eternal youth and life
Is a simply wonderful medley

In the sands of the Mideast to this day
Dwell Enkil and Akasha
The rulers of the vampire, werewolf and zombie races
Our beloved mother and father
