The Valter Realm.

A Nightmare Realm that was created with the joint support of the four greatest Guardian Houses. Lilith, the mastermind behind this project, went back to the Moonreaver House to facilitate and oversee the construction of this Nightmare Realm.

Like the Moonreaver House's own Nightmare Realm, the Valter Realm was created using a complex array of dimensional magic. Using my blood as a catalyst, Lilith and the Moonreaver House were able to create an entire dimension hidden from prying eyes and provide a magical-rich environment.

The Valter Realm had everything a normal Nightmare Realm would have. A massive size that could easily fit one or two countries. A Vampire-friendly environment where the Blood Moon reigned over the skies. Hundreds, if not thousands, of buildings for the residents of the Valter House. And magical defences to prevent invaders from sneaking into the Progenitor's home turf, detecting and annihilating them before I could even lift a finger.

However, compared to regular Nightmare Realms, the Valter Realm had one feature that set it apart.

The World Tree.

Or, to be precise, a replica of the World Tree sprung out from the nutrient-rich soil and reached for the Blood Moon that hung over the entire dimension. It wasn't as large or powerful as the original World Tree that stood in the centre of the Elven Forest. It was akin to a young sapling that was merely a few hundred years old. However, the essence hidden within the replica was undeniably as potent as the World Tree itself.

Ever since Sora had decided that I was the World Tree's saviour, the Elves and the Shadowgarden House have pledged their allegiances to me. Even if it meant splitting the power of the World Tree in half to plant a part of it in the newly created Valter Realm.

With the second World Tree at its core, the Valter Realm wouldn't have the instability issue other Nightmare Realms might face. Even if I didn't provide my blood as a catalyst, the Valter Realm could easily last thousands of years without maintenance.

However, the World Tree wasn't the only thing special about the Valter House.

Situated on top of the canopy, in the gap between the World Tree and the Blood Moon, there laid a floating castle. Easily five or six times larger than any dwelling in the real world, the palatial mansion towered over the entire Nightmare Realm as an Emperor would.

Ornate pillars of gold held the massive marbled roof together, and the moment one walked into the main gallery, one would have thought that they had entered a video game depicting an ancient pantheon of Gods. Onyx marble laced the bottom floor of the palace, while numerous murals depicting the stars and trees decorated the entire castle.

I could see the influence of the two Houses that built the Valter Realm. While there were hints of dimensional magic in-built with every brick in the palace, I could sense notes of the Shadowgarden House's influence with the numerous flora and natural energy hidden within the walls.

But that was just the beginning.

With over a hundred rooms, the floating palace had more than enough space for my small family of seven. My parents would be living in one of the many chambers of the palace, and it was specially designed not to inconvenience their everyday lives.

On the other hand, my four lovers had their rooms specially designed.

Irina's room was in a cold basement just as large as an underground bunker. As a girl who didn't like the Sun too much, it could be said that a basement was the best room for the Winter Goddess. Not just that, the Everwinter House went to great lengths to build magical Winter elements for their former heir, even sacrificing their prized collections to strengthen Irina's chamber.

Lilith, as one of the creators of the Valter Realm, had spared no expense in designing her own chamber. It was fully fitted with a library, a research room, a laboratory, and other contraptions that would help her progress as a theorist. As for her own bed chamber… Let's just say she added her unique kinks to it. So much so, I was tempted to stop my tour and remain with her for an hour or two.

Ysabelle's chamber was a little less flamboyant. She didn't need much in her chamber as a pure martial artist. Most of her requests were centred around the training hall where she could practise her flashy swordplay and train her body to the fullest extent. At the same time, since the Blackburn House had provided the most manpower to the Valter Realm, she didn't want her room to feel completely different from her subordinates.

Rosa's room, on the other hand, had the most unique design. Contrary to the palatial aesthetic, the green-haired Goddess had decided to make a tree into her living quarters. It was similar to the hideout she'd once brought us back in the Elven Forest, and it had Elven infrastructure blatantly displayed all over the room.

Rosa even added some of her more… mature BDSM tastes to the Elven architecture, but that's a story for another time.

And finally, saving the best for last…

My own room.

Truth be told, my chamber wasn't just designed for me alone. It was clearly evident, based on the large bed that could easily fit ten people. However, moving from the bed, my personal quarters had an array of amenities that were truly fit for a King. My own training centre, research facility, a control room to monitor the entire Valter Realm… The list was endless.

Furthermore, since it was meant to be the centre of the Nightmare Realm, my chamber had the most concentrated magical output of the dimension. Although I didn't need the additional magic power, the fresh air and liberating atmosphere did wonders in improving my mood.

And as we gradually reached the final leg of the tour, our group reached the main hall of the Valter Palace.

There, five main thrones awaited us.

Formed in a semi-circle shape, the five thrones each had a unique charm. The first of which was a throne made from pure ice and snow. Crafted with a magical substance that would never melt, the throne was just as exquisite as majestic. The next throne was a seat carved out from pure astral rock. Imprinted onto the luminous chair was the power of the Moon, an otherworldly power that few could replicate, even amongst the well-researched Moonreaver House.

The following two thrones were equally as majestic. Black volcanic rock ingrained with precious jewels decorated the third throne as an ever-lasting obsidian flame flickered within its crown. It also possessed a mysterious glow that would ingrain fear upon those who dared to look straight at the august throne.

The fourth throne looked fairly simple, but its interior was anything but. A chair made of vines and roots, blessed with natural and elemental energy, made the throne stand out from its ostentatious sisters. Yet, even though it didn't have an oppressing presence, the throne itself was breathtakingly beautiful. As if it would charm those who stared at it for too long, sending them into a dreamland where they could never return.

And finally…

"Jin, you can take your place on your throne."

"Lilith… You really went all out for this."

"Of course I did!" My Bloodmate giggled with her white fangs bared. "It's going to be the seat of the Progenitor, the absolute pinnacle of the world. We can't skimp on its design, now can we?"

"..."

I sighed and resigned to my fate. I knew that my life would have been different since becoming a Progenitor, but actually seeing my throne in person… My mind was now ready to abandon my past as a human. I was no longer Jin Valter the poor human cripple.

But Jin Valter, the Progenitor of Vampires and the world's new sovereign.

I approached my throne and carefully caressed the stitching. Coloured in white, golden and red, the throne was made to fit a King. Its royal colours were striking as they were majestic, and the white cushioned seat was something I could sit in forever. And looking behind the massive throne, I could see the artificial Blood Moon shining in from the outside.

It had been a long time since I'd last seen the Blood Moon.

Smiling, I couldn't help but reflect back on my journey to this throne. What it represented in the present and what it will symbolise in the future.

But… I couldn't have done any of this without my precious lovers.

No, I shouldn't delay it any longer.

"Irina, Lilith, Ysabelle, Rosa… Girls, I know it's a long time coming, but now that we're finally here, I can confidently say this."

My eyes turned red as I stared at the four girls who shivered at my gaze. We were connected in soul and blood. Therefore, they were able to sense my emotions and guess my intentions. Irina, the only one who truly knew what I was going to say, smiled warmly as she looked at me with pure adoration. As for the other three girls, they shot me expectant looks with their fingers interlocked in prayer and their bodies naturally gravitating towards me.

"Let's get married."
