We're back on chapter 13.

REMINDER: I DO NOT OWN LEGEND OF KORRA OR ANY OF THE CHARACTERS.

Vaatu hovering above the Tree of Time looking down at Korra, Mako, and Bolin. Unalaq, looking up at Vaatu in amazement. Unalaq turns to the Avatar and the two brothers, who are standing behind him.

Korra starts addressing the light spirit within Korra. "Raava and Korra, nothing could stop this moment. Harmonic Convergence is upon us again." Vaatu said.

"I'm not going to let you fuse with Unalaq. You're going right back in that prison." Korra said. "Wait, fuse with 'him'? What?" Vaatu quicky asked.

Korra enters the Avatar State and uses large blast of fire at Vaatu. She catches Unalaq with airbending, lifting him off the ground, and flings him back through the portal.

Korra out of the Avatar State and turned to Mako and Bolin. "Don't let Unalaq back in the Spirit World."

"We're on it." Bolin said.

Mako and Bolin run through the portal, and Korra turns back to Vaatu, who is charging right at her. Korra reenters the Avatar State and charges at Vaatu with a thrust of firebending.

Meanwhile, Tenzin, Kya and Bumi walking through the Spirit World.

"Jinora. Jinora's spirit, do you hear me? It's your Uncle Bumi."

"Ah, this isn't working. We can't just randomly wander the Spirit World, call out for Jinora, and expect to find her." Tenzin said.

"We just need to employ the simply rules of tracking." Bumi said before he kneels down. "First, we locate her footprints... then we follow them."

"Do you even know what spirit footprints look like? Do spirits even leave footprints? Face it, your tracking skills won't work in the Spirit World." Kya said before she sits down on the ground in a meditation position. "Let me try something." Kya is performing mantra meditating. "Jinora is over there. I feel a lot of spiritual energy coming from that direction."

"We're in the Spirit World. There's spiritual energy in every direction." said Bumi said.

"Enough! We can't do this by ourselves. We need a spirit guide." Tenzin said.

Tenzin walks away followed by Kya and Bumi. They approach a hole in the trunk of a large tree with a glowing star inside.

"There." Tenzin looks into the hole. "Spirit, hello. I'm sorry to disturb you, but I am in need of your assistance."

"You dare wake me, human? Humans in the Spirit World belong in one place only." said the voice inside the hole.

A dark spider spirit emerges from the hole and charges at the three humans. The spirits perspective. Bumi and Kya run away, followed by Tenzin; the spirit chasing them. The three at the edge of a cliff as they jump off and land below, dazed. Tenzin airbends everyone to their feet.

Bumi starts brushing off dust. "Well, that didn't work. Now where are we?"

"We're completely lost." Tenzin said.

Back at the portals, where Korra is using all four elements to launch several attacks at Vaatu, only to have Vaatu dodge them. Korra enters the Avatar State and charges at Vaatu, and using airbending and firebending, destroying parts of his essence in the process. Korra propels herself over the ground with firebending, while Vaatu attacks her with his tendrils. She breaks his hold on her and charges at him with firebending, obliterating a large portion of him. Vaatu turns back to Korra and knocks her off before slamming her against a rock with his energy beam. He ensnares Korra with vines, incapacitating her.

"No!"

At the South Pole, where Mako and Bolin are in vigil and in fighting stance. Followed by an unknown portion of the forest where a mysterious assailant attacks them with rapid ice spikes. Mako gasps while his brother protects him with an earth wall. Mako firebends from behind the wall, while Bolin earthbends in the direction of the assault. The brothers look on in silence, before they were interrupted with a barrage ice spikes from the opposite direction. The brothers manage to dodge the attack by separating. Mako attacks with firebending, while Bolin somersaults while earthbending. When he bends another rock, he is struck by an ice spike. The rock managed to protect him, but the impact threw him toward Mako.

"I don't know if we can win this fight." Bolin said.

"We don't need to win, we just need to stop Unalaq from getting back in the Spirit World." Mako said.

The brothers are attacked with another barrage of ice spikes, but Bolin stops the attacks with an earth wall.

In the Spirit World, Tenzin, Kya and Bumi wander about a mysterious spirit forest, completely lost. When they walk past a spirit mushroom, Tenzin turns are look at it. "We're walking in circles." he said before he points at the mushroom. "I've seen that same spirit mushroom five times."

"That's not the same mushroom." Bumi said. "Yes I am." said the spirit mushroom.

"See? Even it knows we're lost."

Bumi gets annoyed. "Oh sure, listen to a fungus over your own brother. Shame on you."

Kya walks up to her brothers; suspiciously. "What's that?"

"Mushroom? Is that you?" Bumi asks.

"No, wasn't me." the spirit mushroom answered.

A figure approaches the siblings, causing them to gasp in fear and caution. The mysterious figure, who turns out to be Iroh and a knowledge seeker.

"Iroh?!" Bumi went in surprised mode. "How...? Where...? It's been so long." Tenzin said.

"Almost forty years. It's nice to see you again." Iroh said.

"How did you know we were here?" Tenzin asked.

"My friendly spirit fox told me you were lost, I came to show you the way out." Iroh answered while stroking the spirit.

"Iroh, we are grateful, but we're not looking for the way out. We're looking for my daughter." Tenzin said.

"I'm sorry to hear that, Tenzin. But you shouldn't be here, Vaatu has escaped and darkness threatens to take over."

"I'm not leaving until I find Jinora." Tenzin determined.

"I understand. But I beg you to be careful, if you travel too deep into the Spirit World, you could end up in a place where only the lost will ever find you."

The siblings look at each other in confusion. As they turn back, they noticed that Iroh had disappeared. Tenzin tries to catch up, but stops and contemplates.

"A place where only the lost can find you...?" Tenzin gets an idea. That's it! I know where to find Jinora!"

Back at the portals, Korra struggles with the vines. She takes a deep breath and enters the Avatar State, breathing a large breath of fire at Vaatu. She frees herself by breathing fire at the vines before resuming the battle, where she attacks Vaatu with air, water and fire, before knocking him with two earth columns and a water blast. Korra approaches Vaatu on an air spout before trapping him in an air bubble, a ring of water, fire and earth, similar to what Avatar Wan did 10,000 years ago.

"I'm locking you away for another ten thousand years, Vaatu!" Korra said with the voice of her past lives and Raava's. Korra prepares bringing Vaatu into the tree.

At the South Pole, Mako and Bolin are kept in vigil, with two earth walls to protect them.

"Unalaq?" Bolin is peering over the rock. "Are you out there? He must've gone home?"

As Bolin peers over the rock, his ex-girlfriend peers over from the other side. "Hello, my feeble turtle duck."

Bolin is shocked at his discovery before Eska knocks him off with waterbending. Mako turns to look at Bolin but Desna emerges behind him. Before he could retaliate, Desna knocks him off with waterbending toward Bolin. When the brothers have recovered, a large water blast knocks them off, unconscious.

Unalaq rides a wave. "Don't let them escape this time."

Unalaq walks into the portal, with his children looking at each other with unsure looks.

Back at the Spirit World, Tenzin, Kya and Bumi are standing outside the hollow of the tree where the dark spider scorpion spirit resides.

"Are you this is the best way to find Jinora?" Bumi asked.

"Trust me." Tenzin said before he attacks the spirit with an air blast. "Hey, you! Spirit! Wake up!"

"You again?!"

The spirit emerges from the tree, attacking the trio. The trio who are captured by the spirit in a web. The large spirit is dragging them to an unknown location. The spirit soon stops and swings her prisoners for them to look at a place. The place, which is a canyon with sharp rocks. Inside of the canyon is obscured by a thick fog.

"I thought we were gonna be taken to a prison?" Kya said.

"This is a prison."

"Welcome to the Fog of Lost Souls. You will never escape." the spirit said. As it walks away, it throws the trio into the canyon, who scream in the process.

Meanwhile, at the portals, Korra is nearly successful in locking Vaatu into the tree. As the ball glows, Korra is attacked by a water blast, allowing Vaatu to break free. Korra looks on to see Unalaq preparing another water stream, which knocks her out.

At the South Pole, Eska and Desna are dragging Mako and Bolin away. Unknown to the twins, the brothers soon regain consciousness and look at each other before nodding in agreement. Mako kicks a blast of fire at Desna to free himself, before throwing another blast at Bolin and Eska, separating them. Bolin run toward his brother, earthbending two earth columns to knock down Desna and Eska. The brothers run into the portal, where they see a free Vaatu and an unconscious Korra. Desna and Eska run through the portal.

"Stop!" Eska shouts before she bends out two streams of water and traps Mako and Bolin in ice blocks.

Korra stands up to see Vaatu approaching Unalaq. Mustering as much strength as possible, she throws a fire blast, which Unalaq blocks with a blast of water.

"Vaatu, it is time." Unalaq said. "Destiny awaits."

Vaatu stood there in silence. "Umm… what destiny?"

"We are supposed to fuse as the Dark Avatar and change the world." Unalaq said.

"With YOU?" Vaatu asked before he bursts with laughter. "You only have one element. You can't be an Avatar without other three bendings. The Avatar mastered all four elements. And that is what I want. Besides, I have a different and better idea in mind."

Vaatu flies over and enters Korra, who stumbles and struggles before standing erect again, with the imprint of Vaatu on her chest, and her eyes glowing orange-red. Korra approaches the Northern portal and touches it. The overlapping portals energize, engulfing Korra with purple energy, who lets out a blast of dark energy from her mouth. A blinding light shines from her body.

"No!" Unalaq shouts in disbelief.

As the energy dissipates, Korra opens her eyes, which glow orange-red, creating the Dark Avatar.

"We are now one! Now, a new era of darkness will begin! And I will rule the universe. But first, I'll destroy you now. You and Azula served your purposes." Vaatu said in Korra's body.

"I wished to lead a new era for spirits and humans! I wanted to change the world. And you took it all away from me! Now, you will pay!" Unalaq said.

"Oh, I like to see you try, Chief of the North."

Unalaq and Korra charge toward each other.

Meanwhile, Bumi, Kya and Tenzin in the Fog of Lost Souls, where they wander aimlessly.

"What kind of prison doesn't have any bars or walls? We can walk right out of here." Bumi said.

"The Fog of Lost Souls is a spirit prison for humans. I read about that in ancient text. The fog is actually a spirit that infects your mind and slowly drives you mad, imprisoning you in your own darkest memories."

Kya turns to Tenzin with an uneasy look. "How long can we be trapped in here?" As Kya asks, Zhao, who has grown old since the time of Aang, walks by them.

"I am Zhao the Conqueror." Tenzin's and Kya's eyes widen in surprise and turn to see Zhao."

"I am the Moon Slayer. I will capture the Avatar. I am Zhao the Conqueror. I am the Moon Slayer. I will capture the Avatar."

"Hopefully we're not trapped in here as long as that guy." Kya said.

Zhao notice Tenzin. "You, you're him. The last airbender!" He grabs Tenzin."

Tenzin gets terrified. "Ah, no! Get off me!" Zhao drags Tenzin toward him.

"You've grown, Aang. But I will still defeat you." Kya and Bumi drag Zhao away with Tenzin staring at him in horror, Kya and Bumi push him away with Kya waterbending, the group ran away hastily and fearfully. "Come back, Avatar. Face me! I am Zhao the Conqueror. I will capture you! Victory will be mine!"

Zhao fades into the fog. After they escape Zhao, the group's waists being tied together by Tenzin with a rope.

"If we stay together, we'll find Jinora and make it out of this fog." Tenzin said.

Meanwhile, at the South Pole, where Unalaq and the Dark Avatar emerge, with Korra chasing him. Korra attacks with firebending, which Unalaq neutralizes with large ice walls. Both make their way out of the encampment. Unalaq attacks Korra with airbending, but misses. Korra attacks Unalaq with ice shards, which he blocks before gaining altitude and assaulting Unalaq with large rocks. Unalaq breaks the rocks with two water whips and direct them toward Korra. Korra stops the whips with a large ice disc, and throws Unalaq off toward the ground. Unalaq lies there, looking at Korra.

"I'm as stronger as ever in this body. I cannot be beaten. You lose, Unalaq. Now, die." Vaatu said.

Korra, inside her body attempts to struggle free from Vaatu, but her spirit soon weakens and faints. As she nearly passes out, the light spirit inside her begins calling her out.

"Korra, this fight is not over." Raava's voice said.

"Raava." Korra's voice said.

"Vaatu cannot win. Do not give in to ten thousand years of darkness. You are the Avatar."

Korra's eyes light up. She stands there with a golden glow around her and the golden glow turns purple. Unalaq tries to attack her, but his water blast is dodge by purple glow around her body. Korra stood there, mindless with orange-red and white eye glows.

back at the Fog of Lost Souls. The siblings continued searching for Jinora.

"Jinora! Jinora!" Tenzin called out.

"Wait a second." Bumi said.

"What, do you hear something?" Tenzin asks.

Bumi stares around in morbid fear. "Yes. They're all around us. The cannibals, my God, they're everywhere."

"Bumi, you must focus your mind. Right now! There are no cannibals." Tenzin said while Kya looks suspiciously at herself.

"Yes, there are! They're gonna eat every last one of us!"

Kya screams, startling her younger brother. "Who the hell are you two? She prepares to untie herself.

Tenzin stops his sister. "Kya, we're your brothers. You must remember, before the fog infects you."

"No, you're just a vision. I have no family. You can't tie me down."

"They're closing in! I gotta get out of here!" Bumi said before he unties himself and runs away, screaming. As Tenzin tries to catch up, his sister unties herself and runs in the other direction, screaming before disappearing in the fog.

"No! Bumi! Kya! Come back!"

Tenzin airbends the fog away at both directions. As the fog returns, he doubles his power to dissipate the fog, but it still returns, leaving him alone before he is obscured by the fog.

Back at the portals, where Desna and Eska approach the frozen Mako and Bolin.

"Please, let us out." Mako begged.

"His grovelling is pathetic." Desna said. "But I do enjoy the sweet scent of desperation." Eska said.

"Come on, your dad has become an evil monster. He's gonna bring on eternal darkness." Mako said. "Why the hell would you protect someone who doesn't care about you at all?"

"Father was going to let me expire when we tried to open the northern portal. Perhaps we should rethink our position." Desna said

"Yes! I know you'd listen." Mako said.

"No. Don't listen to him. His words are poisoning your mind." Eska said before Bolin weeps bitterly. "What's with this outburst of emotion?"

"I'm sorry, I can't help it. It's just so sad that I'll never be with you again." Bolin said while weeping. "What? Explain yourself further." Eska ordered.

"Eska, I've always loved you. And I always wanted to be with you. But now that the world is ending, I'm never gonna get that chance."

"We could have been together, but you left me at the altar." Eska said angrily.

"No, I was scared. I was scared of my true feelings for you. Gah, I should have never left you. I'm sorry. And I'm sorry that we'll never have the chance to rekindle the dying ember that was our love into a big fire of love flames."

As Bolin continues weeping, Mako looks on with unsure looks. Eska looks at Bolin with confusion before kissing him. The ice around the brothers melt. Eska stops kissing Bolin.

"You'll never defeat my father. But, should you survive, perhaps we could spend eternal darkness together." Eska said.

Mako taps Bolin on the shoulder before both brothers run away.

"Wow! That was the best acting I've ever seen. You completely fooled her." Mako said.

Yeah right, huh. That was acting." Bolin said before he wipes a tear.

The twins watches them. "They will certainly perish." Desna said.

As the brothers run out of the portal into the South Pole, they witness Unalaq and Korra. They run to them and Mako sees Korra's eyes glowed red-orange and white eyes and her purple body.

"What did you do to Kora, you bastard?!" Mako yelled at Unalaq.

"I didn't do this. Vaatu betrayed me!" Unalaq said before he uses waterbending to knock out Mako and Bolin, but they dodged. The brothers prepare to attack Unalaq, but he easily neutralized their attacks and sends out a large ice spike, knocking Mako and Bolin unconscious. Desna and Eska enters the portal and run towards their father. They stopped when they see Korra's body being possessed.

In Korra's mind, where Korra, Raava and Vaatu are ready to fight.

"This body isn't big enough for the two of us, Raava." Vaatu said wickedly.

"You can't win, Vaatu!" Raava said. "Yeah, we'll kick your butt out of my body and back to your prison." Korra said before she uses firebend on Vaatu, who dodges the fire and grabs her neck. He throws Korra on the ground, leaving her unconscious.

At the Fog of Lost Souls, Tenzin is trying to keep himself sane.

"You must stay focused. Remember who you are Tenzin. You are the son of Avatar Aang. You are the hope for future generations of airbenders. The fate of the world rests on your shoulders. But what if I fail? Then your father's hopes of the future dies with you. I can't fail. You will."

Tenzin covering his ears, while sagging to the ground, arguing with himself. "Ah, stop it! I am the son of Avatar Aang. I am the hope for future generations of airbenders. I am the son of Avatar Aang." He starts hallucinating, he looks up to see an image of his father standing before him.

Aang's image appears from the fog. "Hello, my son."

"Dad, I've failed you. I am no spiritual leader, and I've let the world down. I'll never be the man you were." Tenzin said sadly.

"You are right. You are trying to hold on to a false perception of yourself. You are not me and you should not be me. You are Tenzin."

A puff of smoke engulfs Aang, when it disappears, he becomes a reflection of Tenzin. Tenzin stares at his reflection and gives a determined look before standing up.

"I am not a reflection of my father. I am Tenzin. I am Tenzin!"

As Tenzin speaks, a glow of light illuminates the sky, dissipating the fog. Tenzin looks on in amazement and scans the surroundings for his daughter.

"Jinora!"

Tenzin hugs his daughter, who was kneeling dejectedly before carrying her. He finds his elder siblings, who have succumbed to the effects of the fog, and leads them out of the valley. When they exit, the fog returns.

Bumi gets gazed and confused. "Huh? What happened?"

"I think our brother saved us." Kya said.

"Dad." Jinora hugs her father.

"You'll be okay, sweetie. I'm here." Tenzin said.

A light butterfly spirit flies onto Jinora's arm. "What happened? The last thing I remembered was dark spirits taking me away."

"You were trapped in the Fog of Lost Souls. And I wasn't going to let you stay there." Tenzin said.

"I'm so happy to see you, Dad." Jinora said.

Two more light butterfly spirits fly onto Tenzin and Jinora. Bumi and Kya join in the hug. They are prepare to leave. Jinora, however, stops and turns back. "The world is in trouble."

"What are you talking about? How do you know?" Tenzin asked.

"I can feel it." Jinora answered. "What happened?" Bumi asked.

It's Korra. She's been possessed by Vaatu." Jinora said before her father, uncle and aunt went in shock. She passes a light butterfly spirit to her father. "This light spirit will guide you out of the Spirit World. I have to go help." She fades away.

"Jinora, wait!" Tenzin reaches out for Jinora, but she disappears before he could. Bumi and Kya look on in surprise.

Back in where Raava and vaatu are locked in battle. Vaatu knocks Raava down.

"You lose, Raava! Now, ten thousand years of darkness shall begin! And I will put an end of all these love and peace."

"Not if I can help it, Vaatu!" Korra stands up. Then Aang, Wan and all the previous Avatars appeared. The Avatars and Raava charges at Vaatu.

Unalaq watches Korra's mindless body, her mouth blasts a purple beam to the clouds, creating a storm and an impact that tossed Desna and Eska away but Unalaq. He picks up a walkie-talkie.

"Azula, come here quickly! We have a problem."

Two spirits in Korra's body! Can she survive that?!

Let's find out on Chapter 14.
