Fifty years ago, the sky split open and portals unleashed monsters and chaos upon the world. Faced with this threat, some humans received a unique gift: a player system, with classes and skills similar to a video game. Among them, ten legendary heroes, the Ten Kings, founded the Ten Great Families who carry their heritage and power, passed down from generation to generation. Every child of these great families awakens at birth with an innate class and skills. In the country of Veledris, there are only two of these great families, powerful and influential. Damons Ravencier was born into one of them. But unlike the others, he received no power at birth. Rejected, banished along with his three young sisters who also showed no awakening, he survives in the shadows, working multiple jobs to protect the only people that matter. Then, one day, an ancient demonic system — also rejected — finds him and chooses him as a candidate for a deadly competition: the Throne of Demons. Seven chosen ones, guided by demonic AIs, fight to become rulers of the demons. Damons did not choose this fight out of ambition, but out of necessity. To protect his sisters, he must become the most feared Demon King of Veledris… and perhaps the entire world.

I believe my saving grace was when he wanted our first time to be when I finally had my wolf. “I want to deflower you when you have your wolf and know we're mates. I heard it's a magical feeling. I'd want to experience.” he had said. “What if I'm not your mate?” I asked, but he never answered. I should have known his earlier declarations were false. He won't love me if I'm not his mate. Today is my 21st-birthday. My worst nightmare came. I'm not his mate. But here he was marking me as his chosen mate in the woods at our usual spot.

Will I ever tell him about the son conceived from our first encounter in the woods?

They once called him Ahzrael, the mind behind the infernal legions. Alone, he could bring down kingdoms, scatter armies, and challenge the will of gods.

Cast down, consumed by the very black flames he had taught others to wield. Erased from history. But he is not gone. He will rise again. And this time… no one will stand in his way.

When the sky cracked and death fell from above, cities burned and millions vanished in screams and smoke.

In a world obsessed with strength, he is forgotten—discarded like ash in the wind. Yet from his grief, something ancient begins to burn. Not a gift. Not a miracle. A fire. A vengeance. A reckoning. This is not the story of a hero chosen by fate. This is the rise of the Unmarked—and the world will remember what it tried to forget.

Synopsis Il y a 1 an, les premiers « Portails » se sont ouverts. Le ciel s'était brisé, des fissures s'étaient formées. C'était la "Grande catastrophe". Des milliers de démons sortaient des fissures qui s'étaient créées et commencèrent à massacrer les humains, qui étaient sans défenses, sans pitié. Les humains étaient impuissants face à des ennemis possédant une puissance et des pouvoirs surnaturels. Ils ne pouvaient être que de simple spectateurs, et des victimes. Mais un jour, un certain humain s'est ''éveillé''. Il avait obtenu des pouvoirs spéciaux, des pouvoirs surnaturels qui pouvait lui permettre de se battre d'égal à égal avec les différentes armées. Suite à ça, de nombreux humains se sont eux aussi éveillés. Ce fût le début de la formation de l'armée du monde humain, Terra. C'est ainsi que les préludes de la guerre du 'Ragnarök' débutèrent.

Deep in the Void a universe called the Dream Universe made up of planets called the Realms. A place where all those who cultivate and who strive to ascend into Cosmic God status is the goal. Here the Dream Universe is governed by a Cosmic being known simply as the World. The World crowns kings to rule and chooses only those with the potential to join the Primordial regime. Every hundred years each who are crowned are given something called the King's Test. Since the World does not personally take part in this test they summon a champion from the Realms with the same potentials as the Kings. They are King Slayer warriors with strong power and skill chosen to either die showing a king's potential, or kill the king to make way for a new one. This particular test is different. This is an eradication of King's who have abused power and caused strife among the realms erupting into a civil war. The newest King Slayer is one who is not only powerful, but carries a Thread of Necessity with a destiny to bring great change to the Realms. All the World wants is for the wicked Kings to fall and clean the slate. The King Slayer wants power and freedom. But both don’t realize how different this Test will be. Author Note: First volume I throw you into the story. I wrote it where it builds and the world around it builds as it goes along. You learn the back story of the Slayer in volume 2. I wanted to stand out and immerse you into the world I’m creating.
