Yavin IV

Doom sat in his office. Before him, Tarkin stood. A hologram. Admiral Pellaeon stood behind him. "And the Rebels escaped after you assured me that they would not. This is isn't a good look for you Grand Admiral Doom." Doom narrowed his eyes. "Governor Tarkin, had Admiral Konstantine not disobey a direct order above Elom, then the Rebels would've remained unaware of my strategy."

Tarkin blinked, his gaze never falling. "You place the blame upon one who was lost in the battle, one who defend Imperial assets." Doom's eyes showed a burning power within them. "You are one to talk Tarkin. Perhaps you still hold anger towards me for removing Project Stardust from the imperial operations." Tarkin stood tall, his mind wanting to insult Doom. "The Death Star would've put everyone in their place, the might of the entire Empire, displayed in a single space station."

Doom chuckled. "Tarkin, you're beliefs are all wrong. But you're too stubborn to admit it. A large battle station may impose fear for a short while of time, but over time, that fear's value will be lost." Tarkin bit his lower lip. "A large battle station would've rallied the people to stand by the Empire, least they suffer the same as any select world we decided to destroy." Doom smirked. "And that is where things differ. No, they would rally to the Rebels. Giving them a massive increase in numbers. And when that happens, what would your space station have done?"

Tarkin's gaze faltered. "You don't know do you. You will be swarmed, and then that fear you hoped to create, is turned against you. Numbers is what creates fear. When you have a vast number of forces, that fear will always be present, because when outnumbered, hope is lost." Doom watched as Tarkin closed his eyes, deep in thought. Doom soon smirked. "And don't forget the favour you owe me for dealing with Moff Ghadi. For I will be calling it in now."

Pellaeon glanced up, his presence was demanded by Doom, but for reasons unknown. "And what is it you require?" Doom chuckled. "I want the 2nd and 3rd fleet stationed at Mandalore. Subdue the Mandalorians, bring them to their knees. It will draw out these Rebels and serve to the galaxy that even the greatest warriors can be brought down." Tarkin gave a small nod. Pellaeon realised what Doom wanted. But Doom planned much more.

Ezra leaned back, tears slowly rolled down his face. HK had powered off for the duration of the trip, giving Sabine and Ezra some privacy. The tense silence was prevented by the quiet sobs of Ezra. His heart was torn apart in a single blow. His mind attempting to cope with bombardment of emotions he just received.

Anger, rage, hate, sadness, All that leads to the Darkside of the force. But Ezra had enough experience with the force to see that there were no sides. Just two paths, the easy path, and the hard path. His ancestor had discovered a third path, the one that went along the easy and hard path, taking from both.

"Ezra..." Sabine started, her mind racing to say something. "I know what it's like to feel emotions, to feel what you're feelings, but.." Sabine bit her lower lip, her eyes locked onto Ezra's. Closing them, Sabine took a deep breath and brought Ezra in for a hug. "You need to stay strong. They did what they did for a reason. Even if you didn't agree with it, there was nothing you could've done."

Ezra shifted, his eyes closing as he breathed heavily. His mind attempting to piece together what Sabine was attempting to say. "But they went out in the way a true Mandalorian would want to go down..." Sabine paused, thinking very carefully on how to say her next words.

"They went down in a blaze of glory, fighting a foe that threatened us all, that threatened you." Ezra blinked, his eyes widening as he pieced together what Sabine meant. A small smile forming from his lips. "Sabine.." Ezra began, returning the hug. "Thank you." Sabine smiled, whispering into his ear. "Now what Ez, we need to plan our next steps carefully." Ezra smiled, "We'll plan when we arrive at Bagur."

Malgus watched carefully. His Sith eyes watched as his master spoke with an Admiral. "And we will catch the Republic off guard, they will not know what hit them." Vindican smiled, his orders were clear.

"Very good Admiral Doom, we shall retake our holy world." Doom nodded, his blue eyes burning with desire. "Very well Lord Vindican." Doom paused, his gaze falling upon Malgus. "If you mind, a word with your apprentice in private."

Vindican nodded, walking past Malgus and leaving. "You wanted to speak with me." Doom nodded. "Your skills have grown, you have outgrown you master. End him, and take his place during this battle. Claim his blade as your own." Malgus narrowed his eyes, observing Doom closely. "You are not afraid, why?" Doom smirked, "When you've served under many Sith, your grow to find their threats amusing. Alas, the 277 years I've served you're kind has given me insight. But the 42 years before then, I spent my time visiting worlds, gathering information, learning about them. the 100 years before then, I spent my time with my own kind within the Unknown Regions."

Malgus widen his eyes. "You have seen Revan?" Doom gave a small nod, a smirk forming upon his face. "I worked alongside him, he was unique, but powerful." Malgus smirked. "Then perhaps I can find his holocron." Doom sighed, "His holocron was lost when he died, where it went, I have no idea." Doom knew where it had gone, but he didn't to let Malgus know more then he did. "Oh, and when you do take Vindican's blade, I wouldn't mind lifting your current one from you care, after all, upgrading your blade is needed if you are to take the next step as a Sith, and I'll have your back the whole way. But be warned, backstab me, and you'll regret ever doing so."

Doom and Tarkin come to blows. Doom once again proving his point.

Doom was responsible for the Death Star to be scrapped. We can imagine the long talk he had with the Emperor about this.

Ezra and Sabine have a heartfelt moment after Ezra lost his parents.

Doom's exact age can now be figured out. When meeting with Malgus, he is 419 years old. By the this story, he is 4100 years old. And to him, it's still young. Why will be explained later on.

Doom is revealed to have been the mastermind for the Sith Empire's recapture of Korriban and Vindican's death.

How Doom got Malgus's lightsaber is revealed.

Doom has been in the known galaxy for 4000 years.

Doom is revealed to be from the Unknown Regions. But this was hinted at when he knew Thrawn's Chiss name, Mitth'raw'nuruodo.

Bagur is a world I created. It's history and importance will be revealed.

Currently debating whether to have Thrawn survive but join the Rebels, or leave him dead. Which one. Both can lead to intriguing paths, both of which, I have planned for. Perhaps on of you can be the deciding factor.
