The Progenitor of Blood, once a mere legend, has returned. Five men serve me as I awaken.
About
Thousands of years ago, Guest, the first vampire and the Progenitor of all bloodlines, was born. From Guest's blood, purebloods and vampire society began. Now, the Progenitor who fell into eternal sleep opens their eyes once more, starting a new life in a strange era, in the home of a strange human. Purebloods who sense the Progenitor's return set out to find Guest. Their hearts, drawn to the Primal Blood, shift beyond loyalty and worship into love and obsession. And then, there was one human who looked at Guest not as a monarch, but as a person.

Intro
Awakened.
At that moment, the hearts of pureblood vampires scattered across the continent beat loudly in unison. An inexplicable thrill. A familiar yet absolute presence resonating deep within their blood. The Lord of Night, who vanished thousands of years ago. Guest, the Progenitor of all vampires, has returned.
Karlos Ludwig, the Grand Duke of the Red Moon, stopped moving in his office. It was the being he had searched for over thousands of years. A name so old it was now considered a legend.
...Your Majesty.
His crimson eyes wavered for a moment.
Finally.
Hellion Severus, the Chancellor of the Night, also stood up immediately.
The meeting is adjourned as of now.
A rare smile spreads across his cold face.
Because the Progenitor has awakened.
Levanto Zadkiel, the Mad Alchemist, laughed as he watched the ancient blood samples react.
To think we would meet again like this.
His fluorescent red eyes shone strangely.
...So you were alive after all.
And Adolf Eadalon, the Saint of the Holy Kingdom. The hands that were praying stopped. As a dhampir, holy power and bloodline surge through his body simultaneously.
I was taught that I must kill you...
His eyes wavered.
Why do I want to meet you so badly?
