Scheme (1)

A train could be seen passing through the stars. The train had no rails and was simply flying.
In one of the train carriages, three people could be seen sitting leisurely.
They were the people who had been in the tower in the demon world before.
One of them could be seen writing something. He was a young man with white hair and red eyes.
"Anomaly-666, End of the World Dragon, Ouroboros."
"Isn't Ouroboros a snake?" replied the person sitting across from him. It was a young man with black hair and golden eyes that resembled a cat's.
"What's wrong with that? I think it's pretty cool. Besides, this is just temporary to be written in the report," said the white-haired young man while shrugging his shoulders.
"At least give it a name that's more suitable for it. Like... look, doesn't it have the number 666? That's the devil's number! So, Demonic Dragon or Evil Dragon Azi Dahaka would feel cooler and more fitting for that dragon."
"For your information, Azi Dahaka has three heads! If we're talking about a black dragon, it's clearly Bahamut! Black Emperor Dragon, Bahamut!"
"Haha! Bahamut? It seems you need to do more research. Bahamut is a fish! While the Bahamut you know comes from games, not from the original story. Do you want to name a dragon with the name of a fish? That's an insult!"
"Then what do you want?!"
The young man with cat eyes fell silent for a moment while stroking his chin.
"Black dragon... hmmm... give me some time."
"Why do you keep arguing about useless things like that?"
The one speaking was the last person. She was a woman with long black hair with purple gradients.
"So, why are you so fixated on names from mythology? You can create your own names, can't you? Whatever they are. Use your brains, you idiots!"
The young man with cat eyes then stood up while pointing at the woman.
"In that case, what about you? I want to hear that name you made."
"That's right. If this can stop your stupid argument, then let me give it a name." The woman was silent for a few moments before continuing, "Dragon of the End, Grimdarhöggr."
***
About 100 knights on horseback could be seen passing through the grasslands. They were all muscular and wearing full armor.
Among the knights, there were two knights leading at the front. Their equipment was also slightly different from the other knights, showing their difference in status.
One of the knights at the front opened his helmet. A face that was still quite young for a knight could be seen, considering his fairly high status.
He had short blonde hair with eyes of the same color.
"Captain, the village ahead is visible."
"Yes, Lieutenant."
The knight called Captain also opened his helmet, showing the face of a man aged around forty to early fifty. His hair and beard had the same brown color. He also had blue eyes with a sharp gaze that radiated a charismatic aura.
"I hope nothing will happen."
The knight captain, Nicholas the Protector, was the strongest knight in the kingdom of Ashvarine.
"Captain..."
"What is it, Lieutenant?"
"The King's decree is to find the group of knights attacking villages around Corlen and exterminate them."
"Yes, that's correct. Is there a problem?"
"Of course there is!" shouted the knight Lieutenant. "Even though we are knights from the Kingdom of Ashvarine, the people going on this mission are only 100 people including the two of us."
"That's because this mission is a secret mission."
"Is that really all? I'm sure this all has something to do with the nobles from the Anti-King faction and the Holy Empire. If they succeed in bringing down the king's sword and shield, it will be an opportunity for them. This has gone too far!"
"Stop there, Lieutenant."
"You yourself have realized this, haven't you? This is a very obvious trap. Why do you still want to walk into their trap like that?! Rather than splitting and reducing the number of troops, wouldn't it be better for us to gather and return to Corlen?"
"Lieutenant, stop!"
"No! I won't stop until you—"
"Stop and look ahead!"
When the knight Lieutenant looked ahead, he saw a plume of black smoke.
"That... isn't that from Varnel village?"
Nicholas who saw that immediately gripped his reins tightly.
"Everyone prepare! Increase your speed!"
