Interior: Concord Dawn, Mandalorian Knights enclave, briefing room.
Bardan showed Galen an intercepted and garbled transmission.
Appearing via hologram, King Dendup of Onderon said, "Onderon… needs… help… stop… Sith… inva-"
"Shall we warm up our basilisks, Lord Mand'alor?" asked Bardan.
"Yes, and contact the Jetii Watchman of the sector, if he or she is still alive, assuming they have one."
"Master Vos is there on assignment."
"Oh, wonderful, he's probably what drew the Sith there in the first place."
A few hours later.
Exterior: Onderon, Iziz, merchant square.
Onderon militia General Tandem called, "Lt Gerrera, on your left!" whilst shooting at stormtroopers.
Using a vantage point, Steela sniped a pair of bucket heads, "Saw, you in position?"
From a rooftop a few blocks away, Saw Gerrera lined up his shot with a rocket launcher, "Target acquired," and blew up an Imperial troop carrier.
Helping get civilians out of the crossfire, Lux Bonteri asked, "Did the call for help even get through the blockade?
I hate to say it, but if we don't get reinforcements soon, the city may be lost."
Assisting the resistance alongside Sugi, Embo, Dengar, Aurra and Seripas, Fennec provided cover fire for the militia, "He will come, I can already hear intense theme music."
"He who?" asked Saw, over the radio.
"You'll see."
With a sonic boom, several objects descended into the atmosphere and began obliterating the Sith's air support.
Dozens of Mandalorians emerged from several troop carriers all over the city, bringing the battle to a stunned pause.
"It's the Mandalorians!" exclaimed several civilian onlookers.
"For Onderon!" called Mandalore, who'd repainted his pauldrons dark green, as he held aloft his white blade then charged the Imperial ranks.
Within the hearts of the Onderon militia, the fires of hope blazed anew, rekindled as the powerful presence of Starkiller became known to them.
On the other hand, the Imperials who crossed his path fell in droves before him.
Sith forces were powerless before him, and their troops were outclassed by the superior soldiers and warriors of the Mandalore clans.
In the skies above Iziz, Fenn Rau, Carth, Juno, Iden and Asajj provided air support with their squadrons.
Exterior: Space, Onderon.
Starkiller's fleet, under the command of Admiral Dodonna and Commander Sato, battled the Imperial fleet.
Soon thereafter.
Exterior: Onderon, Iziz, palace courtyard.
Standing over King Dendup and an unconscious Quinlan Vos, Sion raised his crimson blade to strike them down, but stayed his hand as he felt a shift in the Force.
"The Republic's Dark Knight," snarled the Sith Lord as he turned around, "we meet again." while the King got to his feet and backed away, dragging Vos with him.
"Darth Sion. Who else of the old Sith has the Emperor revived?"
"You've seen one more, he consumed Taris while you played with Dooku's droids."
Firing his Westar-34s, Galen knew they wouldn't hurt his opponent, he only sought a momentary distraction for the King to get further away with Quinlan.
Firing so fast they were about to explode from overheating, Marek threw the pistols at Sion who cut them in half at the same time as their explosion, damaging his hilt, destabilizing the blade.
Enraged, Sion readied his juyo stance.
Taking the stance of vaapad as he drew the starsaber, Starkiller immersed himself in duelling Sion whilst subconsciously using battle meditation to strengthen the resolve of his allies.
30 mins later.
Disarming Sion, Starkiller cast a wall of light upon the walking husk, cutting him off from the Force, reducing the body to dust.
Though he figured that wouldn't stop him for too long if the Emperor had anything to say about it.
Force healing Vos who woke up, Galen asked, "Sleeping on the job, Quinlan?"
After rubbing his temple, Vos looked up, "When did you get here?"
"In time to save your life," answered Galen.
As the King looked at him, Galen asked, "King Dendup, are you alright?"
"I am, thanks to you, my friend."
Exterior: Onderon, Iziz, palace courtyard.
Standing at attention with a cheering public watching, Starkiller shook hands with the King who awarded him a medal.
"For your bravery and courage this day, I thank you on behalf of the people of Onderon, Mandalore," said Dendup who held out a small box revealing a beautifully crafted pair of blaster pistols, "Please accept these as a token of our gratitude, and put them to good use."
Studying the guns, Starkiller's HUD searched his database for and found a match before he had a psychometric vision which went unnoticed.
Later.
Interior: Starhawk, briefing room.
Via hologram, Galen folded his arms to the Council, "You do realise the King gave them to me, expecting me to use them?
Not to let you lock them away in your vault of Sith artefacts?
And I do need a new pair of pistols, since I sacrificed the ones I was using."
"You're planning to use these dark side artefacts in the field?" asked Obi-Wan, "and Jedi aren't supposed to carry blasters."
"We're not supposed to take military roles either." pointed out Depa, "General Kenobi."
