Hero of Darkness

Rathnaar Whitlock, the Peak Saint who was once the most feared entity in the world of Vantrea; the one who slaughtered chosen Heroes like cattle and even killed a Royal Dragon showed a temperament of pride while introducing the dungeon boss' real identity.

"The Lightning Dragon Emperor, Vildred."

His words echoed on this floor while everyone was simply too gobsmacked by this fact.

As the words exactly meant… the being in front of them was the Emperor of the Dragon Empire, the strongest empire in the entire world.

[What the shit?! That's the ending arc plotline main boss of the story! Why did such a being appeared out of nowhere?] he asked in a baffled tone.

"What is that child talking about?

Ending arc plotline main boss, what gibberish is he spouting?" asked the humongous and titanic Royal Dragon who was even taller than Blackwall's mythical rank form.

"Ah, don't mind him. He's an otherworlder like all the summoned heroes.

I never understood half of the things they said. Their knowledge and choice of words are confusing." spoke Rathnaar, still showing an unnerving expression.

Even though the Dragon Emperor showed hostility towards him, the former peak saint showed no interest.

"I see. Listen, otherworlder summoned hero.

My name is Vildred Xyvsor Gown Ivrar Mortelix." introduced the dragon emperor in a majestic voice.

"Too long. Didn't read."

Responded Kahn to this unnaturally long-ass name.

The dragon emperor's chest constricted after hearing this unexpected response. This was the first time someone didn't show awe or a respectful tone after he took the liberty to introduce his name.

Although he could kill Kahn for this ill-mannered response… the golden dome made by Rathnaar was impenetrable to the current him.

"So tell me… why are you tied to a chosen hero, Rathnaar?

I thought you hated them and the gods as much as I did." he asked, still leaking his vengeful aura.

"Well… all my descendants are dead and he happened to be the one to find my sealed remnant soul in my empire.

Things led to other things and now we're here. Besides… I hated being confined for a century, all by myself." said Rathnaar using Kahn's body.

Just then… Kahn also spoke using his own body's mouth.

"Can somebody clear out a few confusions for me?"

"How do you two even know each other?" Kahn queried openly now that their situation was at a standstill.

Sigh!

Rathnaar regained control and sighed.

"Listen kid… hear very carefully.

Vildred and I… we were enemies." he revealed.

"Back when I was only an 8th stage saint and just created the Rakos Empire, many chosen heroes and empires associated with Gods were insistently attacking my empire since they couldn't have an existence that didn't worship the gods.

Although I killed few of the chosen heroes who were just as strong as me in those times… they kept coming after me and my people.

Thus, the dwarven blacksmiths who served me asked for a Royal Dragon's horn to forge a sword that could help me kill all the other heroes and even withstand a frontal clash against multiple 8th stage saints such as the Emperors and Empresses of those empires.

So with no other choice left and the fate of my empire at stake… I went to the Dragon Emperor." iterated Rathnaar.

His expression turned somber right after revealing this information.

"Kastvabaan is one of the four regions protected by Dragon Kings." he spoke.

"Wait… there's a Dragon Emperor and a Dragon King?" asked Kahn.

To his question, it was Vildred who responded in a dreary tone.

"In my empire… the strongest Royal Dragon of that generation gets to become the Dragon Emperor.

The others who are in the line of succession but failed are titled as Dragon Kings.

And there were 5 Royal Dragons at that time.

I was the reigning Dragon Emperor and my brothers and cousins were the 4 Dragon Kings." he explained.

From here on, Rathnaar continued again…

"Kastvabaan was the western region of the dragon empire. In a way, it was similar to Verlassen fiefdom.

Unlike the other empires… It's very big and thus, one Dragon King was appointed to protect the 10 thousand kilometers of that part of the region.

I chose that place because it was the closest to me. And there…" he spoke, his expression turning heavy.

"I challenged the Earth Dragon King, Svatlforkin." he stated.

"If I won… I would get one of his dragon horns and if he were to win… he'd get to make me his slave via a Core-binding ritual." he stated, but soon… he let out a smirk while trying to hide his laugh.

"That idiot, who was too overconfident since he was a royal dragon, fell for it and lost. Ha ha!" he laughed openly.

Rumble!

Vildred let out his wrathful aura again but couldn't help but keep listening.

"When the time to honor the deal came… Svatlforkin attacked me instead.

So one thing led to another and I ended up killing him." revealed Rathnaar as if he was greatly wronged.

"And after his death… this lightning bolt of a dragon here reached the site of the battle.

I left since my goal had already been realized." spoke Rathnaar in a chivalrous tone.

"Left my buttocks! You ran like a coward!" shouted the dragon emperor in rage as he remembered their fight, his blood boiled from rage after reminiscing the old hatred.

"And don't trust this lying scum, child. This bastard never tells the whole truth.

He actually attacked Svatlforkin with the full intention of killing him.

Just to make a statement to all the other empires and deter them from attacking his own empire for a while." rebutted the dragon emperor.

"Hey hey! What's with that language?

We could be said to be peers. So please refrain from spouting such lies." spoke Rathnaar as if he was wrongly accused of something he didn't do.

Kahn, Vildred and even all his subordinates rolled their eyes, none believing his righteous words. All of them were fully aware of what kind of lying and cunning man Rathnaar was ever since they first met in Rakos Empire.

"Peers my claw nails!

I'm a thousand years older than you. Show some respect, you buffoon!" exclaimed Vildred in fury.

"Heh? Why would I be respectful to someone who couldn't beat me?" taunted Rathnaar.

"Beat you? I remember we fought for a few hours and you ran away. He he!" the dragon emperor made a questionable claim.

"As I recall… you were screaming in anger because you couldn't catch me even while I ran away with your cousin's corpse with me. Ha ha ha!" mocked Rathnaar in return.

"Ha! Do you want to go for another round, you impertinent trash?!

Oh wait… you can't.

Because you're dead! Haha ha ha!!" laughed Vildred, his laugh leaving shockwaves after shockwaves in the 20 kilometers radius.

"Whatever. It's still better than being sealed in a cage for a thousand years.

If I was in your place…

I would've committed suicide out of shame." said Rathnaar as he flipped a middle finger to the Dragon Emperor.

Dozens of minutes passed and both peak existences kept insulting the other side in one way or another while name-calling and hurling profanities at each other.

Kahn understood one thing clearly. That two of the supposedly strongest beings in the world…

Were actually just the Strongest Nutjobs.
