The Crystal King Council and the host, known as Harumi and (Y/N) are in Vengestone's warehouse looking at Lloyd unconscious, locked in a cage made of the same stone.

- So. What are we going to do with this ninja?- asked Vangelis.

- Nothing. The Crystal King has some plans for him.- Harumi announced.

- Is he even alive? He's been unconscious for some time.- said (Y/N) with worry.

- Relax, (Y/N). As long as we need him, he will live.- Harumi replied with a smile.

(Y/N) looked at her with furrowed brows and sighed, crossing her arms. There was nothing she could do. Not now, she has no support. Even if she wanted to attack them, she would lose.

- What are we supposed to do now? Did you summon us for no reason?- hissed Pythor.

- No, Pythor. I have.... The Crystal King has a plan that you are needed for.

- And that plan is...?- sneered Aspheera.

- Patience, damned! Wait to be summoned. The spiders will lead you to your chambers, and now.... GET OUT OF MY SIGHT!- she yelled.

Everyone scowled at Harumi's shriek and nodded their heads frantically. The spiders emerged from the holes in the walls and began to lead the council members to their designated places. Everyone except (Y/N).

- Why don't you go rest? This plan involves you too.- Harumi said, looking at the cage Lloyd is lying in.

- Because...I want to talk to you.- said with a slight hesitation (Y/N).

- About what?

- About...um...because Lloyd said that, how Garmadon lost control of that stone monster and hit the building you were standing on....

- The building collapsed and I collapsed with it and died?

- Yes. How did you survive?

Harumi fell silent for a moment and giggled quietly under her breath. (Y/N) raised an eyebrow at her.

- Please. Did you really think that a person like me. The one who founded a criminal group and awakened an evil lord, couldn't survive such a thing?

- You know.... I don't know. I think you're a.... Too clever.

- I appreciate the compliment. But you're right. It's a fact, I was injured, but I got away before anyone noticed me. I waited for the right moment. Then I started working with HIM. I help HIM rise to power and in return he gives me something I lack.

- I'm guessing this is about your died family, isn't it?

Harumi's eyes widened in surprise and she looked at the yellow ninja with shock written all over her face. (Y/N) smiled crookedly and placed her hands on her hips, directing her gaze to the cage trappted Lloyd.

Harumi nodded slightly and also looked at the cage. The white-haired girl felt a poke on her leg and looked down. One of the spiders was poking her and pointing at (Y/N).

- You know what, go rest, you have a job to do, soon.- she stated and started walking.

(Y/N) looked at her confused. Harumi noticed that, she wasn't following her, so she turned around.

- Are you going or not? Unless you want to sleep in the hallway.- she sneered, giggling.

- I forgot what a mean, sneaky bitch you used to be. - laughed (Y/N) and started to follow Harumi.

Harumi laughed at that and two girls started walking to their chambers.

After walking through the halls for a while, Harumi and (Y/N) arrived at their rooms, which were right next to each other.

- Well, it looks like we're neighbors.- Harumi grumbled.

- So it seems. Just please, don't come to me at night for sugar.- laughed (Y/N).

Harumi laughed and stepped into her room. (Y/N) did the same after a while. The sight of the room shocked her. The room was incredibly well decorated for being underground.

A/N: This is what your room is like, just imagine it's windowless.

(Y/N) walked over to the bed and sat on it, stroking the sheet with her hands, looking around , ''her'' new bedroom. The girl in the back of her mind felt bad for betraying her friends. Still, she denies her thoughts of betraying her people. She is troubled by Lloyd's situation and Harumi's words. What does Crystal King need Lloyd for and what will happen to him, when we no longer need him.

However, she was frightened only by these thoughts.

"What will my friends say, when they find out?", "Is Lloyd in danger of dying?", "How will the knights and mom react?", "What will Aya think?".

Her restless thoughts were interrupted by a knock on the door.

- Who's there? And who dares to interrupt me in my rest!?- she growled.

- Ehhh, ninja! Come out! That Harumi is calling us! It's time for this whole plan!- hissed Aspheera at her through the door.

- Well, let's go now!- she shouted, opening the door.

At the opening of the door, Aspheera flung it at her face. Snake hissed at her, and (Y/N) shrugged her shoulders with an innocent smile. They both moved towards the council meeting room and sat down at the table where everyone was already gathered.

- You are late.- Pythor remarked condescendingly.

- Oh, shut up, Pythor. You can't rest in peace anymore, when someone come into your room with her tail.- told (Y/N), sitting down in her seat.

Everyone at the table snickered or giggled, masking it with a cough. Pythor sneered and shook his head.

- The Crystal King has given us a sign. Now it's time to attack.- Harumi said.

- Attack? Great, just on who?- asked (Y/N).

- Not at who, but at what, (Y/N). You will attack the Spinjitzu Monastery. According to information, HE knows that the ninja and their master are holding the Golden Weapons in the Monastery. Your task is to steal the weapons and bring them to our King. This will give us a great advantage in the battle later.

Immediately, the heart (Y/N) stopped at this information. She's not ready for that, not now! Everyone will think she is a traitor. 

- Does this theft also include destroying everyone there and everything?- asked Aspheera with a smile.

- Whatever you want, as long as the weapons arrive intact and complete. You can even destroy the entire ninja asylum. Or maybe even kill them and all the allies.

The council members almost exploded with excitement and whispered to each other with sadistic smiles. (Y/N) clasped her hands on the armrests of her chair and sat rigidly. She bite the inside of her left cheek and looked at Harumi with shock.

Harumi looked at her with a irritating smile.

- This is your test of loyalty to our King, (Y/N). I hope you pass it without a problem. Remember, HE'S counting on you, princess.- she winked at her, then got up from her chair.

- So, my dears. Let's do it!- she called out and left the room, humming a song to herself.

All the council members rose from their seats and left the room. Pythor crawled up to (Y/N) and put a hand on her shoulder. The girl looked at him with fear. The snake flashed her a smile.

- Come, (Y/N). It's time for our revenge.- he hissed excitedly.

(Y/N) nodded to him still fearful and nervously got up from her chair. They both followed the other council members. They all grabbed their weapons and left the base.

= Skipping Time=

In the blink of an eye, they found themselves in front of the gates of the Monastery. Aspheera without hesitation, with her staff struck the gates, blowing them up. The Council without hesitation and quickly entered the Monastery and they went towards the secret entrance of the garage, while plundering, destroying and partially setting fire to the temple.

(Y/N) first entered the elevator followed by the others. After getting to the very bottom their eyes were shown. Nya, Skylor, PIXAL, Wu and Saber.

- This will be easy.- Aspheera hissed, as they all started walking towards them.

The heroes all gasped, widening their eyes in shock. Not at the evil ones, but at (Y/N), who was walking side by side with them.

- (Y/N)! What are you doing? We were worried about you!- shouted Saber.

- Forgive me, my friend, but.... I'm not here to say hello.- she said with no emotion in her voice, keeping her hand on the hilt of her sword.

- What are you talking about!?- cried Nya.

- I am.... A member of Council of the Crystal King. My companions and I have come for something that belongs to Him.- she said.

- WHAT!?- shouted everyone in shock.

- Aspheera!- cried Wu.

- Hello, weakling!

- What is the meaning of this?!

- I think, it's obvious. - sneered Vangelis.

- We came here for....- started (Y/N), when she was interrupted by Aspheera's scream.

- REVENGE!!!

The other council members slapped their hands on their foreheads and shook their heads.

- No, you idiot! We came here for the Golden Weapons!- hissed Vangelis.

- It's not always about that revenge!- continued Pythor.

- To some extent.- muttered (Y/N).

Wu twirled his staff while the others stood in a defensive position.

- Then take it!- challenged Wu.

- I was hoping you would say that!- said Aspheera and (Y/N).

The two sides rushed at each other with momentum to fight. (Y/N) fought Nya and Saber and the others fought PIXAL, Wu and Skylor.

- (Y/N)! What's gotten into you!-Nya screamed, avoiding a sword cut.

- None of your business, sis!!- growled (Y/N), avoiding a blow from Nya.

- You are not yourself, (Y/N)! They control you!!- shouted Saber, throwing himself at her and knocking her onto her back.

- No one is controlling me! I chose this path myself and now.... get out of my way!!!- she screamed and threw the lion away from her, with her legs.

Nya and (Y/N) rushed at each other, throwing a series of punches, even though she was on the wrong side, she wanted to play fair.

(Y/N) hit Nya in the face with a right hook, forcing her to huddles. Taking advantage of this, the brunette grabbed her adoptive sister by the legs and spun around her and throwing her. Nya abruptly picked herself up off the floor and began to inflict (Y/N) a series of punches. The yellow ninja wanted to kick her in the stomach, but Nya grabbed her foot and pushed her to the floor. She sat on top of her and began to inflict punches to her face. 

Pythor, fighting PIXAL, noticed this and disappeared. He sneaked up behind the Master of Water and grabbed her by the back of her costume. The snake knocked her back hard, knocking her to the ground. (Y/N) picked herself up off the ground and wiped the blood from her nose and lip. 

- Thanks.- she breathed out to Pythor.

Pythor nodded, and (Y/N) leapt over the snake's shoulder, slamming her fist into Saber's mouth, pushing him away. Saber growled in pain, landing on the ground.

- Finish Nya, and I'll take care of the lion. - she instructed quickly, running to Saber.

- Okay, whatever you want.- he hissed and crawled up to Nya.

The groups fought each other fiercely. Saber threw himself at (Y/N), who made an effective avoid, his jaws and wrapped her arms around his body. The lion tried to break free, but (Y/N) squeezed his weak spot near his ribs, knocking the lion out.

The lion fell to the ground, giving (Y/N) a chance to reach the computer. She quickly started typing a special command on the keyboard. And a dresser with four Golden Weapons came out of the floor.

The villains, seeing this, pushed their enemies hard away from each other and grabbed powerful weapons.

Pythor grabbed the Sword of Fire and threw it to (Y/N), who caught it perfectly. She smiled and her eyes flashed yellow.

- Aspheera!! Use an immobilizing spell for five minutes! And let's get out of here!!!- she ordered.

The snake nodded with a smile and she swung her staff, which glowed with a pink aura.

- Stop, when I tell you to. Stand still and don't move, when the magic inside you is slumbering. Stand like a stone statue and be silent.- she said quickly.

An aura shot out of the staff and hit the heroes, effectively immobilizing them.

- Great, now, let's get out of here!!

Everyone rushed to the elevator, and as the gates closed the council began to laugh at their success.

Using her weapon, (Y/N) went into the living room and set the curtains on fire. Her eyes permanently glowed yellow and she laughed under her breath, sinisterly.

On her way out, she wandered the tip of sword across the floor, setting the floor on fire. The fire began to spread quickly through the Monastery. Judging from the various electrical equipment in the temple, one could honestly say that there would be an explosion. 

The council left the building and looked at the burning temple with smiles of satisfaction. The fire had already reached the roof and started creeping up the building.

- Something tells me, there's about to be a big explosion, my companions.- (Y/N) said.

- The time for revenge has come Wu!!! YOU WILL DIE CONSUMED BY HELLFIRE!!- shout Aspheera, laughing.

- Our mission complited. It's time for us to go.- said Pythor.

- Congratulations, (Y/N). We underestimated you.- said Vangelis.

- Brilliantly executed attack.- Aspheera praised her.

- You're going to be evil.- laughed Pythor, patting her on the back.

- And the ninjas don't expect it.- Vangelis laughed as well.

- Yes. FINALLY THEIR TIME WILL COME!!- cried Aspheera.

- Yes.... Time.... The end of their damn glories and victories.- said quietly (Y/N) and the color of her eyes didn't change a bit.

A creepy, sinister smile spread across her face and a sinister laugh came from her lips.

- Welcome, my friends, to my darkside. And you, my dear ninjas... sleep with one eye open.... For your close, has just become your enemy.

She uttered it in a voice as low and cold as ice. The ninja had finally met their equal opponent. She will bring power to this world. The power of vengeance, pain and destruction. She will end the existence of the ninja once and for all. She.... She will bring here and Knighton what she has always hesitated to do.

She.... She will become.... A evil like the kingdoms have never seen.
