Ambition? Loyalty!

What exactly happened during that time?

From the moment Horus Night Haunter, appeared, he has been known as the chief culprit of the Horus Heresy.

But now, with the scene in the Klein bottle and the Night Haunter's detailed narration, even Sanguinius is getting impatient.

When Sanguinius returned to the Imperium, he was personally mentored by Horus, and Horus relationship was the best.

Now, in his original destiny, Horus has unwittingly become the chief culprit of the Horus Heresy.

Of course, the most important piece of news is another one.

The first Primarch to sacrifice himself!

What exactly happened during that time?

Sanguinius needs to know.

"Don't be too hasty, Great Angel. You only guessed half of the riddle correctly. Who's the other one? You can try to guess."

"However, I can give you a reward for the other half. If you can guess correctly, I'll tell you right away what happened to Horus."

"Is it Roboute?"

Um?!

Guilliman couldn't sit still any longer.

You, the universally beloved Great Angel, actually used me as a scapegoat to find out what Horus really did?

But what devastated Guilliman was that not only the Great Angel said so, but others also tacitly agreed.

"Wrong, it's not Roboute," Curze said.

Hearing Curze say that, Guilliman finally breathed a sigh of relief.

At the same time, he gave Curze a grateful look. Luckily, Curze spoke up for him; otherwise, he would be in deep trouble right now.

"Great Angel, you're letting your concern cloud your judgment. Think about it carefully; it definitely can't be Roboute."

"It's hard to say," Fulgrim said. "You just said yourself that in the original destiny, you were also a traitor. Who knows if you were the Corruption Curze?"

Upon hearing Fulgrim's words, the Night Haunter sat down and began to laugh, laughing so hard that tears almost streamed down his face.

"Haha! Fulgrim, I haven't even said anything to you yet, and you've already jumped out on your own."

"Oh my, you're really cracking me up! Alright, since you've made me so happy, I'll be merciful and tell you."

"Listen up, all of you! In the original destiny, among all the Primarch of the Imperium of Man —and I'm Primarch to the Fulgrim was the traitor!"

"On the contrary, Roboute, whom you all consider ambitious, was the most loyal one in his original destiny!"

"Ha! What a damned fate for this son of a bitch, how ironic!"

"And listen to me carefully, Fulgrim."

"Although I'm Horus Heresy like you, I'm a traitor, you're a bastard!"

You're spouting nonsense!

"Your master is right here, just ask him and you'll know," the Night Haunter said nonchalantly.

Then Fulgrim looked at Slaanesh.

"He's right, Little Fulgrim. If Mr. Han hadn't interfered in this destiny, then you would be my Daemon Prince."

"No! This is impossible! The Emperor's Children is the enemy who killed his father! The Emperor's Children will never betray him!"

"Hehe."

The Night Haunter chuckled coldly twice and then fell silent.

You shout slogans loudly, but after the Horus Heresy, you're the most active one.

"Fulgrim, what the Night Haunter said is true," Curze said.

"Curze! Don't be fooled by him! He's a devil!"

"Yes, I am a devil, a devil who crawled out of my original destiny to make you realize who you are!"

"So, my Teacher, is this answer a pleasant surprise or a shock to you? Haha!"

The Night Haunter mocked Fulgrim's flushed face.

"Everything the Night Haunter said is true. Think about it, Fulgrim, before you met your Dad, didn't you notice anything different?"

Curze looked at Fulgrim calmly.

At this moment, Fulgrim was also lost in memories.

He began to see his past self through his current perspective, and then he started to tremble uncontrollably all over.

"No, this isn't real, none of this is real!"

"You noticed it too, didn't you? Before you met Dad, that increasingly intense, uncontrollable Vanity in your heart," Curze said.

"I... I..."

Fulgrim stood there stunned for a long time, unable to utter a single complete sentence.

"What exactly happened? Could you explain in detail?"

"Roboute, the details of this story are going to be very painful to hear. Are you sure you want to hear it?"

"Please be sure to tell us, Night Haunter."

"Although we avoided that fate, it is still necessary for us to know."

Now that Roboute has spoken, no one has any doubts left.

They even hoped that Roboute would speak at this moment.

Because at this point, only Roboute remained loyal to his original destiny.

Half of the others present Horus Heresy, and what happened to the remaining half remains a mystery.

"Since you've asked, I'll tell you. But where should I begin?"

"Let me begin, Night Haunter. I want to know my fate," Horus said.

"Ha, alright then, you can start."

"But you'd better sit tight, because what happened to you after your betrayal and death is truly heartbreaking."

"First, we must begin with Horus being appointed Warmaster after the Ullanor Crusade ended."

"After Horus was appointed Warmaster, the Emperor returned to Terra and began his secret Webway Project. Once completed, this project would starve all the Chaos Gods in the Warp, saving humanity from Warp invasions."

"But with the Emperor's retirement, Imperium power began to be taken over by Mortals. As a result, the power struggles between Mortals and the Astartes increased."

"In addition to Horus's own Great Astartes Supremacy, his prejudice against Malcador, and his affection for the Emperor, this led him to make a wrong judgment."

"A year after the Ullanor Triumph, problems began to arise for Luna Wolves following the death of one man."

Someone died?

"Who died?" Horus asked.

"Sejanus."

"Impossible! This is absolutely impossible! How could Sejanus be dead?!"

Among the Four Kings Council, Abaddon is very capable in battle, but Sejanus has the ability to completely balance the entire Four Kings Council.

During Horus's absence, he was the true commander of the Luna Wolves.

How could Sejanus possibly be dead?

"Heh, that's the truth, Horus. Sejanus, who symbolized your humility and prudence, is dead. No one can now restrain your arrogance and conceit."

"Although Sejanus died, Garviel Loken later took Sejanus place."

"I must say, Horus, your Legion has a lot of talented people."
