Y/N's P.O.V

My escape pod crashes down in the water of Nur.

I put on my oxygen mask and open the pod to swim forward.

Just then I see Kanan and he swims along side me.

We find a hidden entrance and swim into it.

After that we climb out of the water.

Y/N: Sabine, we're in. Do you copy?

Sabine: I copy. Are you two okay?

Y/N: We're fine. I'll contact you when we've got my sister and on our way out.

Sabine: Understood. Be careful, babe.

Y/N: I will.

I look to Kanan.

Y/N: You ready for this?

Kanan: Yeah, let's get your sister.

We sneak out of the room and take out two Stormtroopers ahead of us.

Third person perspective  

Y/N and Kanan sneak into a prison holding area.

It's pitch black and they walk into the center of the room.

Kanan: This feels like a trap.

Just then the lights come on and they're surrounded by a squad of Stormtroopers.

Y/N: Should've seen that coming.

The Jedi raise their hands.

They then see Darth Vader stood infront of them with Serena next to him wearing cuffs.

Vader: You are right, Master Jedi. This is a trap. I knew young L/N would come for his sister.

Y/N: Let her go.

Vader: I will. I plan to give her a choice.

He uses the force and Serena's cuffs fall to the floor.

Vader: First Sister, now is the time to prove your loyalty to the Empire.

He hands her an Inquisitor lightsaber.

Vader: Strike down your Jedi brother and his Master. Prove yourself as a Sith.

She steps forward and ingites her lightsaber.

Y/N: Serena, don't do this. You're better than this. You're not a Sith.

Vader: Make your choice, First Sister. The Empire or your family.

Just then she ignites the other end and throws the saber around to kill all the Stormtroopers around them.

She catches her saber and turns to Vader.

Serena: I choice my family.

Vader: I'm very disappointed, First Sister.

Serena: That's not my name! My name is Serena L/N.

Vader: So be it.

She charges at Vader and locks blades with him.

The two clash sabers as more Stormtroopers come in.

Kanan: Help your sister. I'll deal with them.

Y/N: On it.

L/N ingites his lightsaber and rushes off to help his sister.

The siblings fight together and use their combined strength to overpower the Sith Lord.

Vader force pushes Serena back and she flies back into the wall, losing her lightsaber.

Vader brings his saber down and cuts hers in half.

He turns and locks blades with Y/N.

Vader: You are stronger than I anticipated.

Y/N: (Sarcastically) Ah, thanks. You're so sweet.

He breaks off and jumps over Vader's head to get to Serena.

Serena gets up and force pushes Vader back just before Y/N lands down.

Y/N helps her up and grabs a lightsaber off the back of his belt.

Y/N: Here. Take this.

He hands her their mother's lightsaber.

Serena: Thanks.

She ingites it and the blue blade comes out.

After a few minutes of fighting Kanan joins in on the fight and the three of them work together.

The Sith Lord manages to hold them out.

Vader quickly chokes Serena with the force and throws her towards the wall.

Y/N: No!

Y/N jumps into the air and catches Serena.

They both hit the wall.

Kanan fights Vader alone.

The two lock blades and they move their sabers trying to get an edge.

Just then Vader breaks off and cuts Kanan's arm.

Kanan: Ah!

He then brings his saber down to cut his leg too.

The Jedi falls to the floor.

Vader raises his lightsaber over his head to kill the Jedi Master.

L/N lays his sister on the floor.

He then looks up to see this.

Y/N quickly stands up to jump forward.

He ingites his lightsaber and blocks Vader's before he can kill Kanan.

The Sith looks at the Jedi.

Vader: Brave of you, boy. It seems you're just as stubborn as your mother.

Kanan manages to bring his lightsaber to his hand with the force.

Y/N: What can I say? It runs in the family.

He breaks off and forces pushes Vader back.

Kanan: Y/N!

Y/N looks to see Kanan throw him his lightsaber.

The Jedi catches it and ingites the lightsaber.

He uses Jar'Kai to put Vader on the back foot. Vader then comes back and pushes Y/N back.

(A/N: Just imagine it's Y/N fighting Vader with a purple and blue lightsaber.)

Vader clashes sabers with him and knocks Y/N's lightsaber out of his hand.

Y/N clashes sabers with him before backing up.

He slashes the cables on the ground causing a black out in the room.

The two raise their sabers up before continuing their fight.

As they fight Y/N pushes the Sith back.

The two lock blades, but Vader knocks Y/N back slightly.

He quickly brings his saber down and cuts off half of Y/N's lower arm.

Y/N: Ah!

Vader force pushes him back and he goes across the room landing next to Kanan.

Vader: Time finish both Master and Apprentice.

Just then he sees Y/N's lightsaber fly past him and sees Serena catch it.

She ingites both her mother's and brother's sabers.

Serena: You're gonna pay for that.

She charges at Vader and continues their one-on-one fight.

As they fight the door opens and Sabine flies in on her jetpack.

Sabine: Hey! Up here!

She fires at Vader and he deflects her shots.

One blaster bolt hits the window behind them and it cracks.

Sabine lands down as Y/N and Kanan get up.

Y/N: Sabine, what are doing here?

Sabine: Coming to get you. You were taking to long.

Kanan calls his lightsaber to him.

Kanan: Well, it's time to go.

Y/N: Serena, let's go!

She nods and jumps back.

His sister jumps into the air and lands next to him.

Sabine grabs Y/N and helps him out.

Serena uses the force to break the window and water floods in the room.

The group leaves while Vader uses the force to hold the water back.

Y/N's P.O.V

We run down the halls of the underwater base.

Y/N: Okay, how do we get outta here?

Serena: There are escape pods. They'll get us up to the surface.

Sabine: I'll contact Hera and get us a pick-up.

After doing that the four of us make it to an escape pod.

Y/N: I don't feel so good. I'm gonna...

Sabine: Y/N!

Everything goes black.
