Book II: Spirits
Chapter X: Darkness Emergence
Unalaq looks at Vaatu with awe, his plan has finally bore fruit. He turns to Wan and Korra, who glare at Unalaq. "Raava," Vaatu starts, "Nothing could have stopped this moment, not even your precious humans could keep me in my prison forever. Harmonic Convergence is upon us once more and this time, I will end you and the humans!" Wan clenches his fists as he steps forward, "Think again Vaatu! You're going right back to your prison!" Wan yells.
Vaatu rushes to Unalaq, and the man offers himself with his arms open. Wan enters the Avatar state, blasting fire at Vaatu and Korra catches Unalaq using airbending, he is lifted off the ground and is thrown out of the spirit world via the portal.
Wan looks at Mako and Bolin, "Don't let Unalaq back into the spirit world at all costs!" Wan commands, the bending brothers nod and run to the portal.
"Great, now I have to deal with Vaatu again." Wan mumbles as he and Korra turn to Vaatu.
"We fight once again Wan, don't think you'll be lucky this time!" Vaatu roars as he charges Wan and Korra, who charge forward in the Avatar state. Wan attacks in the air blasting fire at Vaatu who dodges, Korra attacks from behind with earth. Vaatu blasts his beam at Wan who avoids it, and Wan hits Vaatu with another round of fire and water.
Korra blasts Vaatu with a powerful gust of wind, and the spirit is pushed back. Vaatu grabs Wan by his ankle and flings him, Wan catches himself with his airbending. Korra, now leading the charge, shoots a stream of fire that penetrates Vaatu, Korra goes through the opening using air as a projector, and prepares another attack.
However, Vaatu slams the earth to knock Korra back and uses his energy beam to blast the female Avatar away.
She screams and is slammed into a nearby rock. Korra takes the hit hard, and as a result she is weakened by it.
"Korra!" Wan yells, he glares at Vaatu, who begins to focus on him. Wan enters the Avatar state once more, he sends several hits at Vaatu pushing him back and effectively weakening him. Wan throws two earth columns and a fire strike at his opponent.
Wan rises in an air tornado, and begins to trap him in an air sphere with rings of all four elements. "I'm locking you away for another ten thousand years, Vaatu!" Wan proclaims with Raava behind his voice, Wan lowers himself and begins to guide Vaatu to the Tree of Time. Korra gets up, and smiles at Wan. she rushes up to help him. The two are near the tree and Vaatu is almost in, but before Wan can deliver the final thrust of air, they are both blasted away by water.
Vaatu busts free from his cage. Wan and Korra get up. Seeing Unalaq prepare another water stream, Wan jumps down, pulling earth from his feet and with a kick throwing it at Unalaq, who tries to reflect with as much water as he can. When Unalaq looks again, Wan and Korra are gone. Unalaq turns his head, he is hit by a gust of air and he is thrown back with a yell.
Before Wan can make the next hit, Vaatu blasts both Wan and Korra. They are slammed back and they roll on the ground groaning. Wan, panting, gets up, Korra struggles but does so as well. Vaatu approaches Unalaq, Wan attacks again with a blast for fire, but Unalaq blocks with water. Vaatu dives into Unalaq, who screams.
He grins and chuckles darkly as he stumbles before standing up with the sigil of Vaatu on his chest, and his eyes glowing red. Unalaq approaches the Northern portal and touches it. Unalaq is engulfed with purple energy, he screams and lets out a blast of dark energy from his mouth. A blinding light shines from his body.
Wan and Korra shield their eyes and look in horror as purple smoke comes from Unalaq's body, he laughs maniacally as he opens his eyes, as his eyes are dark red.
The dark avatar is now born.
"Korra," Wan turns to his partner, "We need to kill him, He's too far gone."
Unalaq tilts his head, "Mumbling amongst yourselves? I am unstoppable, Dual Avatars." Unalaq says with Vaatu. Wan and Korra prepare themselves for battle. Unalaq's hands rise as the earth rumbles, Wan glances down to see vines trapping them both. The two gasp in shock, Unalaq steps forward, each step brings destruction to the earth. Wan and Korra struggle to escape, "Wan it's too strong!" Korra cries out, Wan pulls on it.
Then he enters the Avatar state breathing fire at Unalaq who screams in pain, then breathes fire at his binds. Korra frees herself as well, Unalaq glares at Wan and Korra- his flesh is charred horribly, but then it regenerates before their eyes.
"Okay, killing him isn't going to work," Korra mumbles. "Then we destroy him." Wan retorts as he enters the Avatar state, Korra joins in. The dual Avatars attack and so does the dark Avatar.
Unalaq chases Wan and Korra. Wan attacks with firebending on his cloud, which Unalaq neutralizes with large ice walls. They are now in the physical world as they exit the portal. Korra attacks Unalaq with a sharp air disk, but misses. Unalaq attacks Korra and Wan with ice shards, which Korra blocks. Wan however is hit. He falls to the ground, Unalaq throws Korra off toward the ground and uses his newfound vines to trap Korra and he makes it tighter and covers her mouth. Unalaq exits his waterspout and traps Wan in a fissure. Unalaq begins to close it with his bending, Wan begins to faint as the walls get tighter and tighter.
"Give in, Your time is over!"
Wan closes his eyes as the light grows dim, and he begins to fall unconscious.
Wan, This fight is not over.
"Raava..." Wan mumbles.
Do not give up hope, Vaatu cannot win. Do not give in to ten thousand years of darkness. You are the Avatar.
Wan's eyes open, pure white, as Unalaq tries to crush Wan, fire erupts from the fissure, knocking Unalaq off and freeing Korra in the process. Wan emerges from the fissure with airbending, he is surrounded by white light and the four elements.
"You will not win!" Wan and Raava say. Wan attacks Unalaq, Korra attacks Unalaq with a fire blast. The two begin to chase after Unalaq, giving everything they got at the Dark Avatar.
Korra and Wan, in sync, use a water whip to trap Unalaq by his hands, they pull him at the same time freezing his hands. Unalaq uses this to his advantage and pulls them in. Wan and Korra enter the Avatar state. As Unalaq enters his Avatar state, Wan and Korra get closer to Unalaq, his head twists and turns violently, Vaatu emerges from his mouth. Korra and Wan try to attack with fire but Vaatu thrusts himself into Korra and Wan's mouth, nose and eyes. He forces both of Raava's halves out as the Dual avatars scream in agony. Unalaq slams her together making her whole again. Wan and Korra watch as Unalaq traps Raava in a water bubble. Unalaq grins victoriously as Vaatu goes back inside him.
Bolin and Mako are running, now free from Eska and Desna, "He got the light spirit!" Bolin screams, the brothers attack Unalaq, but the Dark Avatar easily defeats them and knocks them unconscious with ice spikes from the ground.
Wan tries to reach out to Raava, stretching his hand as far as he possibly can. Korra lays on the snow completely weak, helpless as Unalaq starts to unleash his dark bending on the light spirit hitting her. Wan feels the first hit to his soul.
Aang.
Korra feels it as well, her eyes widening at the short but painful stab. However, Wan feels the full blow, he is trembling in the agony. Unalaq delivers another blow, Wan can't take it. He tries to get up however the pain hits him again ten fold. He collapses as he feels another piece of himself vanish.
Roku, Kyoshi.
Wan screams, enraged, The First Avatar stands up again, once more he collapses at the sheer anguish he feels from his soul.
Kuruk, Yangchen, Jung, Lu Lin, Ashita, Salia.
So much knowledge and power is gone.
"STOP!" Wan wails to the top of his lungs, tears falling from his eyes. Unalaq keeps going, getting more relentless, smiling sadistically at Wan's suffering. Wan feels his soul being ripped apart. Unalaq then summons a whip of purple water. Wan rushes over to save Raava trying to summon every piece of strength left. Unalaq strikes Raava with all his might, Wan's eyes and mouth go agape as he sees his oldest friend die in front of him.
Wan's soul shatters as he feels the last one left, the second Avatar. Her silver gaze and her small sad smile crushes him, she vanishes into golden dust. Wan goes limp as tears fall from his face.
Raava is gone
Unalaq laughs victoriously, as he sees the golden dust fade into nothing. His laughter turns into madness, "We did it Vaatu, We destroyed Light!" then the man stops, his limbs stiff. "W-What?"
Thank you human, you've performed a great service to me, but unfortunately however, you are no longer of use to me.
"What, after all I have done?!" Unalaq doubles over as his skin begins to peel, he screams and begins to cry as he feels an overwhelming heaviness in his soul as Vaatu sucks the life out of it. "I've been loyal to you! I've done everything you've asked me!" Unalaq screams, as his black substance reaches his eyes. Tears begin to fall.
Vaatu just laughs at him, No, you wanted to use me as a weapon for your petty human needs. I read your deepest thoughts, you really think I would let a human like you to be my Avatar? Foolish Man, you think that you could control my power?!
Unalaq lets out a high pitch scream as his mouth begins to bubble up with foam like blood. His bones begin to show through his skin. His skin rapidly turns pale.
Korra, still weak from the assault, looks on in horror at the disfigurement of Unalaq, his limbs twisted unnaturally, skin peeling and blood dripping, the man being destroyed both inside and out.
"Our deal! You owe me, you were freed by me!" Unalaq screams, his voice hoarse as his physical body is pushed to unimaginable pain. Ah, how curious. Since when have you ever been in control?
Unalaq screams as his soul is fully corrupted, Unalaq's husk of a body plummets to the ground. A huge burst of black skinny tendrils from his back bursts, as blood and some of his organs fly out a monstrosity arises unlike anything the world has ever seen, it rises and grows. Desna and Eska, who exit the portal to find this thing rising, back up in horror. It was pitch black, they can hear the screams of Unalaq as his corrupted soul and Vaatu are transforming into something diabolical.
Into a monstrosity.
A freak of nature, Wan and Korra are lifted up by the shoulder with the help of Mako and Bolin who watch in terror. The monstrosity rises then it speaks, "N̸o̷w̸,̷ ̶t̸e̸n̶ ̶t̵h̸o̷u̴s̷a̵n̵d̵ ̴y̸e̷a̴r̴s̶ ̵o̶f̵ ̷d̴a̴r̴k̴n̶e̸s̸s̶ ̶b̶e̷g̵i̵n̴s̴!̶ ̴" (Now, ten thousand years of darkness begins!) The monster declares as it reaches up at the portal transporting itself, leaving a huge shock wave that throws everyone behind, making them fully limp.
