Interior: Korriban, Valley of the Dark Lords, Naga Sadow's tomb.
On a joint expedition, Cordova, Cere, Trilla and a CIS archaeologist were deciphering ancient texts.
Sensing someone terrifyingly powerful in the dark side, the three Jedi formed a circle and ignited their sabers.
Exterior: Korriban, Valley of the Dark Lords.
Out of nowhere, multiple Sith Assassins and soldiers appeared and slaughtered most of the expedition's security escort before they could fight back.
Exterior: Deep space.
Interior: Starhawk, bridge.
As he sensed a great disturbance and heard a scream through the Force, Galen, under his breath, said "Trilla…"
Approaching, Tech informed, "We've received a distress signal from an exploration team on Korriban."
Having a very bad feeling, Galen rhetorically asked, "Cordova?"
"Clearly, my Lord."
Removing his helmet, Galen chuckled, "Still getting used to that. Just don't start calling me Darth."
"I assume that's a joke?"
"And a request. I have enough problems with Mace Windu.
It'll be lightsabers out if he hears someone call me that even as a joke or sarcasm."
"Duly noted."
Accessing the holotable, an officer brought up images of darkly garbed humanoids and a broken shell of a man.
Juno asked, "What do the Sith have to gain from Korriban?"
"It is their homeworld," pointed out Visas who'd accompanied Marek.
Immediately thereafter.
Interior: Starhawk, briefing room.
As he spoke with the holograms of the Jedi High Council, Galen said, "If you're going to try and stop me going to Korriban, save your breath,"
Yoda sighed, "Hmmm, deal with this threat, I sense you must.
But beware of the dark side.
The Sith homeworld, Korriban, a dark side nexus, it is."
Weary, Plo cautioned, "I sense a darker hand in this. I'd advise you to be on guard."
"I always am."
"May the Force be with you."
Later.
Exterior: Korriban, Valley of the Dark Lords.
As Galen, Visas, 3 Mandalorian Knights, the HKs, Clone Force 99 and Inferno squad arrived to find a handful of surviving clones held captive, they swiftly intervened.
Igniting the darksabers, Galen gracefully yet fiercely engaged in battle with a dozen Sith assassins who immediately targeted him while the troops dealt with a small garrison of Sith troopers.
As the last of the enemy troops were slain, Galen addressed one of the survivors, "Where's your Jetii?"
"Ori'vod, Prof Cordova, Knight Junda and Padawan Trilla went into the tomb on the far left.
They haven't come back."
"That's the tomb of Naga Sadow, the first Sith Lord to wage war against the Republic.
I'm going in after them."
Approaching one of the fallen Sith assassins, Galen pulled off its mask revealing a bald headed man with blood red skin, yellow eyes and twin tendrils on his chin, triggering his psychometry.
Staggering and leaning on a nearby pillar for support, only for his psychometry to trigger again, Galen clutched his forehead before regaining his composure.
Freaked out, Wrecker looked at the blood-skinned humanoid, and stopped himself from throwing up, "What's that?"
Taking a closer look, Tech answered, "Adult, male, Sith."
"They're creepy."
"They're also native to this desolate graveyard, and were believed extinct until recently."
"This planet is cursed," grunted a wounded trooper, "the sands are said to be so red because the planet itself bled."
"Oh, goodie." scoffed Crosshair.
Interior: Korriban, Valley of the Dark Lords, Naga Sadow's tomb.
Venturing inside accompanied by Visas, Galen sensed the dark taint within the tomb before igniting an ice blue Katana-like blade, revealing two human figures on the ground with BD-1.
As he knelt down by their sides, Galen checked them for pulses, "Cordova? Cere? Hey, wake up."
"G- Galen?" coughed Cere who was dehydrated.
Helping the pair sit up, Galen asked, "What happened?"
"Down the main corridor, there's something there… an artefact of the dark side." weakly said Cordova, "and a sarcophagus in a chamber far to the left."
After healing Junda and Cordova's injuries and giving them a drink of water, Galen said, "I'll take it from here."
"Galen, they have Trilla." informed Junda.
"I'll get your daughter back, don't worry. It's going to be okay."
"Thank you." appreciated Cere.
Turning to the Miraluka, Galen ordered, "Take them outside and stay with them."
"Yes, my Master." obeyed Visas.
Shortly thereafter.
Interior: Korriban, Naga Sadow's tomb, grave.
Having already collected the star map, Galen took the path to the right of the entrance where he found Trilla.
She was bruised, scarred, beaten, stripped, and chained to the stone slab protecting the sarcophagus.
All that remained of her clothes were her black briefs which were pulled down, and a low-cut bra, which was pulled above her head exposing her perky breasts.
Her belt and lightsaber lay on a nearby pedestal.
Rushing to her side, taking off his helmet, and using the Force to heal her wounds, Galen urged, "Trilla, hey, c'mon, please wake up."
Slowly opening her eyes as it all came back to her, Trilla gasped, "Galen?"
"It's me, and I'm here to rescue you."
"He… he did worse than torture me." shuddered Suduri, "a Sith Lord."
Understanding from the context and a psychometric vision, his eyes widened in horror, "That schutta."
As a crimson blade ignited, Galen turned to see the Sith Lord who'd dared harm and defile his friend, and he knew exactly who he was looking at.
"I am Sion, Lord of pain."
"I don't care."
Marek drew his Force-imbued sword which glowed blue, and illuminated the room with the Force.
Fuelled by hatred and anger as was typical of any Sith Lord, Sion attacked the Mandalorian who studied the techniques of his opponent.
Precise and swift, Galen parried every strike as if knowing Sion's moves before he did.
Sion growled, "You will fall, Revan, and I will destroy the Jedi once again."
Galen didn't even bother to correct him.
Through disembodied voice, Meetra cautioned, "Galen, he draws his strength from worlds powerful in the dark side.
You can't beat him in a place like this. And he doesn't die."
"I'm counting on that last part, Meetra," thought Galen.
As he glowed golden with his eyes fiery blue behind his helm, Marek stared into Sion's eyes.
Taking a Mando Juyo stance with his sword, Galen used a variant of Force fury creating an electric judgement aura as he channelled his aura through the blade which surged with electricity.
Suduri could only watch in awe of the fierceness, tenacity and determination, yet tranquil, calm, controlled and graceful movements of the Mand'alor whose presence, in the moment, solely radiated pure light.
Sion cast red lightning, but an unfazed Galen absorbed the power into his blade and deflected it, "I feel your pain, but that anger isn't your own, it's the Emperor's."
"You know nothing of me!" growled Sion as his own attack was sent back at him, half disintegrating his body.
"I know I can't kill you in such an evil place, but I don't have to," countered Marek as he used the Force to heal the red kyber crystal inside Sion's lightsaber, making the hilt explode.
Augmenting his speed whilst the Lord of Pain was distracted, Galen cleanly cut off Lord Sion's head followed by his limbs which dropped to the ground before blasting the pieces with electric judgement, "Try getting up from that."
After processing the fight, Trilla teasingly yet nervously asked, "Not that being bound at your mercy wasn't a naughty fantasy of mine, Galen, but will you free me and whisk me away to safety like a gallant hero? Or are you about to-"
He cut her off mid-sentence, "I'd never take advantage of or intentionally do anything to hurt you, Trilla. You're my friend, and I will always come when you need me,"
"Thank you," appreciated Trilla who shed a tear.
Sheathing his weapons and taking off his helmet, Galen freed his friend who put what was left of her gear on along with his surcoat, then pulled him into a kiss.
Unsure what to do or how to react, he decided inaction was the best course of action.
As their lips parted, he helped her to her feet but she nearly fell back down, so he donned his helm and swept her off her feet before she cried into his shoulder.
Marek carried her bridal style, with a detour back to the Star map, and successfully cast Force light upon it before running like the wind to the exit as the tomb shook and rumbled.
Exterior: Korriban, Valley of the Dark Lords.
Emerging from the tomb as it caved in behind him, with Trilla in his arms, Galen saw the other two Jedi being treated by the medics, "We're done here, let's go."
Cere inquired, "Where are we going?"
"The closest medical frigate where you are getting further medical attention and a full health assessment," firmly answered Galen who turned to the Professor, "that's not a suggestion, Cordova.
That's an order, am I understood?"
"Yes, Lord Mandalore."
"Good."
Concerned, Visas inquired, "What happened to Sion?"
"He's buried and dismembered." answered Galen who held up the cleansed kyber crystal, "he won't be needing this."
Noticing Trilla's state of undress, Cere asked, "Trilla, where are your clothes?"
"Destroyed by that monster."
"Oh, Force, what'd Sion do to you?" asked Cere, fearful of the answer.
"I don't want to talk about it," nervously replied Trilla as her demeanour changed, "not here, not now… please don't make me."
Cere shed a tear, "I won't make you do anything you're not comfortable with, sweetie," and gently hugged her Padawan.
