Chapter 6: Harbinger

White Lotus temple. Northern Water Tribe

Korra just stood in sudden shock, confusion mixed with fear as she watched a woman that could bend all the four elements and go into an avatar-like state. Something she was capable of doing as the mysterious woman's eyes glowed, but felt dark spiritual energy coming from her. Energy she suddenly sensed that resembled a deep connection of the time her corrupt, and power hungry uncle Unalaq when he bonded with the evil spirit Vaatu. The unknown woman then sent all attacks straight at the White Lotus fortress, with the impact of our four elements beginning to affect the guards defending it as the Order charged forth. Korra's eyes glowed as she went into the avatar state deflecting the remaining bending attacks. Gushes of wind and hurtling boulders took out a charging garrison from the Order. Order tanks fired off spirit energy from their cannons as they delivered an area of explosions, leaving Korra to sent a colliding force of ice and earth toward the tanks. White Lotus members began evacuating people since the attack started while Korra head into confrontation the mysterious woman accompanied by the Anarchist Order.

The unknown woman launched hail of ice and earth at the Avatar who evaded the incoming attacks in the air. Korra conjured snow and air at the woman, follow by fire as mysterious woman deflected the fire using air along with fireballs and an earth column to collide with the other incoming attacks. The no named woman took huge amounts of ice and compact it into tiny flakes of hail, then bent it into the sky and has it fall on the Avatar. When one of the bits of hail cracks open on impact; all the compact ice exploding into pieces that tore a piece of her parka and scraped her cheek in the process. Snow struck Korra down before she could retaliate as the woman formed a sharp ice pike, hurtling it at the Avatar. Luckily Korra used firebending to rapidly melt the ice away before launching an earth column, as she was sent flying back only to land on her feet. The mysterious woman in the avatar like state flew in the air as she charged directly

Lin grabbed a White Lotus guard by the collar. "Make sure every refugee in the temple is evacuated!" she ordered. "Move it!"

"Right away, Ma'am!" the guard said as he carried out Lin's order, issuing the evacuation for the refugees in the war with the Anarchist Order. "Begin the evacuation!" he shouted to his fellow white lotus guards

"Is this a dark avatar? Like Vaatu?" Raiku asked

"No, it's not. I can't tell how, but this is different." Tenzin aid seeing the Avatar the mysterious woman of the Anarchist Order. "It's as if this is something or someone we don't know about. Something Korra has never encountered before."

Raiku took a step forth and closed his eyes."Can you feel the same way I do right now, Uncle? Her being the same level as Korra?" he asked with his eyes glowing green as Raiku stared at Korra's fight against the mysterious woman

"I do, and I feel Korra will need help." Tenzin had a troubled look shown on his face watching the battle in the mountains. "Since she's occupied with whoever this woman who can bend the four elements like her and go into another state, it is up to the rest of us fend off the Order until everyone is fully evacuated from here." he declared

"Is there a secret entrance out of the fortress?" Li Mei asked

"The only ones alive to know about it are me and Tonraq. We can evacuate the people away from the battle." Tenzin suggested. "I'll send someone to inform you when it's done."

Raiku nodded. "Good. We need every refugee to flee into the secret entrance."

"We'll stay here and hold them off to buy you some time." Mako declared as he and Raiku head over to Bolin, Asami, and Li Mei's aid

Bolin blocked the gate with a stone wall ten stories high as mechs and Order troops rolled in from the side. Li Mei and Asami started firing at the troops with six guns and sub-machine gun they wield. They began to take cover when a spirit cannon aimed its way at them as Asami and Li Mei along with Bolin jumped away from the incoming blast. Troops stormed the temple only to be blow away by gushing winds and repelled by scorching flames.

Raiku and Mako arrived to assist them. "Need help."

Asami electrocuted a nearby soldier with her electric glove. "That would be an understatement."

Li Mei pointed at the mountains. "Those mountains. We can set off an avalanche if we had something with a lot of kick to make that happen. But we need to get everyone out of the fortress using the entrance."

"While fending off an entire invading garrison. Easier said than done." Raiku said in a nonchalant tone creating a funnel which trapped Anarchist soldiers

Asami ducked Li Mei's head from an incoming spirit shot. "As long as we stay alive." she replied as her and Li Mei fired back with their spirit guns

Li Mei heard the sudden roar with her ears as she showed a cautious look. "Please tell me i'm not the only one who heard that?"

A mysterious creature soar through the fortress, spewing out flames that burned both barracks and guards defending the temple. A giant claw which destroyed an outpost along with killing the men posted there pummeled in the rubble. However, there was one guard being held by the claw as the creature flew up in the sky before releasing him to fall to his death. It was nearly twenty feet tall, scales along with wings and a maw. A broken horn on its left side, as it charged a few guards in flight with fire and earth colliding toward the flying beast. Growling was heard from its maw before a sudden glow started to appear inside the mouth as it slowly opened.

"DRAGON!"

The dragon started spewing fire from its mouth as refugee with a few being injured while the rest of the guards were caught in the flame. This transcend to their deaths for some while only a couple were injured as two rock boulders collide against its face, courtesy of an earthbender guard. The guard screamed and was sent flying away with a hit from its tail straight into a burning hut. The beast grabbed a guard in its claw as it stared deadly at Raiku and the others, with the four backing away while they eyed the dragon. Its maw wide open as an orange light emerged from its mouth, leaving Mako to ready himself while Raiku took a defensive stance to prepare for the attack. A blaze of fire came from the dragon's maw as it began to spew out fire, leaving Raiku and Mako to repel the attack while Bolin hurtled a boulder across catching its attention.

"That has to be the most scariest dragon I have ever seen tonight." he said bringing up a wall of earth from the ground to shield him from the dragon's fire

they dived away from the dragon's fire and went into cover. "What kind of dragon is that? I've never seen a kind like it before." Raiku said. "Looks like one from back in the old days of Lakogi before they were extincted. The only dragon we know is around is Fire Lord Zuko's."

"I'm pretty sure we don't want to find out while we wait for that thing to pick us off." Mako looked to the coming garrison coming inside the fortress, then turned to the dragon.

"Li Mei and I will help with the evacuation."

"We'll be fine. Bolin, go with them." Raiku said as he and Mako bought time for Asami, Li Mei, and Bolin. "Whoa!" he avoided the incoming dragonfire, along with a mid-air of dodging the blow from the dragon's tail.

Mako launched lightning from his hands as the dragon flew away from the attack. "Someone has to distract that dragon. I'll volunteer while you guys hold the defense." he ran launching fireball to get the dragon's attention

Raiku glimpsed to see the garrison rammed themselves inside the White Lotus fortress. "He's definitely going to need help." he said blasting a few Order soldiers with a gush of wind

Mako launched a flurry of fire at the dragon with collided with its own flame as it dived forward in the air toward him. It again spewed out fire from its mouth before attempting to capture the firebender in its maw. Fortunately, Suba tackled Mako and held him in the air while Raiku flew using airbending. Mako launched small ballistic balls of fire, striking at incredible distances at the dragon that evade and deflected it with its wings as Mako dodged the impact. He used two fingers pressed together as a string of electricity came out of his fingertips and shot out. The shot impacted on Lan Du who absorbed the blow as the commanding member of the Anarchist Order redirected at Mako and Raiku.

They evade the blast of lightning as Lan Du formed a whip to send hurtling toward his two opponents summoning a storm as their around his arms. Raiku proceeded to launch a barrage of air fists at following Order soldiers that headed to Lan Du's aid. He began to use combat energybending to deliver pummeling blows at Lan Du evaded and countered using his lightningbending. He launched a hurtling lightning strike at Raiku hat sent him flying back, managing to land on his feet but fall on his back in a quick slide. Lan Du set the fortress in a blaze to cover his escape while Anarchist soldiers providing assistance against the former detective now bodyguard and the snow-haired Arishiakage. Mako lashed out in a fiery spin, before striking a few soldiers using his lightningbender while Raiku let out a funnel that sent them flying and spinning toward the wall.

"Find the others and get out of here. I'll go look for Korra."

"When we regroup with everyone else, I'll give you two a signal. Just look to the sky." Mako said as he went to find the others

Raiku dodge and evade incoming attacks, from benders and spirit weapon gunfire from non-benders as gushes of wind sent them flying at every turn. Unleashing flurry upon flurry of air punching winds to Anarchist soldiers that had them scattered as Raiku dodged a hurtling boulder, before seeing the dragon. Using a funnel to redirect it from the bender who launched it, he used the funnel to shot out boulder across the dragon's face. Raiku suddenly a distant boom as he caught a glimpse of something heading directly toward his way. He prepared himself as the object became closer to see, widening his eyes that it was not an object but Korra. Raiku released a funnel to kept Korra hovered in the air as he caught her in his arms, a monstrous roar followed suit which came from the dragon before it descended between them. The mysterious woman as Raiku fired a blast using combat energybending.

The woman caught the blast in her hands shocking Raiku and Korra ."Enough!" she hurtled it back at Raiku who blocked the attack, but was sent flying back to a wall

Korra ran over to Raiku, but was stopped when an emerging flame and earth wall blocked her way. "Who are you?"

"I am Chaos and Anarchy. I am darkness and bringer of havoc. A destroyer of peace and harmony. I am Fisiuli. I am the Harbinger." she pointed her finger directly at Korra as her deadly gaze grew. "You will kneel, child."

"Why are you doing this? Why start this war?" Korra demanded

"Pure chance. What I seek is something valuable upon the stars that comes on the promised day. I cannot have you or anyone else attempting to stop me." Fisuili paced back and forth. "As long as there is light in this world, there is also darkness. Like there is peace and harmony, there is hatred and war. And like Wan himself, you have the ability to acquire that power within you. To acquire that from the star I seek, but no way of using it."

Korra showed a sudden puzzled look on her face. "How do you know Wan?"

"I know he stopped me from taking what was rightfully mine. I can see his essence from within you and many others."

"Whatever you're planning we will stop you."

Fisuili smiled evilly at the Avatar. "You are not the first to make that declaration and you certainly will be the last, Korra."

"You know my name. How could you even have-" her eyes widened upon realization. "That was you. In that dream! Before you started the invasion!"

Fisuili walked toward Korra before the Harbinger grabbed her by the wrist as they hovered in the air. A funnel forming under Fisuili's feet that kept he afloat. "Indeed I was. Through the life forces of those I consumed upon my resurrection, I realize this world has changed. The reincarnation of every new Raavani. The hundred year war. A city of formed nations into one. I have missed much in time, but utterly pointless." Fisuili kept her eyes focused on Korra with a cold stare. "Beg that I do suceed. For I have endured darkest depths into the shadowly abyss of the spirit world and became the most powerful being this world has never known!" she said tossing to a broken wall near the downed Raiku

"That's not going to happen. I refuse to let it happen!"

"You will try, child. And you will also fail. It's pointless to continue resist." Korra and Raiku looked above the Harbinger to see a fireball in the night sky explode, realizing it was the signal Mako shot out. "You will die on this day, Avatar. Just accept your fate of the fact that you will simply lose."

Korra glared straight at Fisuili widening her stance. "Not here. But that's not why I kept you talking. Enjoy your victory, now here's your prize."

Korra used the seismic sense technique of earthbenders to find the metal ore stored inside expand out as it steamed in whitet hot fire. She pulled out metal from the potentially stone source nearby as the ore she collected was generally refined due to her having the Harbinger speak. She was lucky enough to stall her, but Korra gather a bit of information on what the Harbinger was searching for. For what she wanted to obtain as she shot the white hot iron into the mountain as it came crumbling down. Korra and Raiku ran away from the incoming alvanche while Fisuili fled away on her dragon, as the incoming wave of snow headed their way. Korra would have stopped the alvanche if she could, but was weakened with her battle against the Harbingers as both her and Raiku fall into a hole. This hole lead to an abandoned section of the catacombs underneath the White Lotus fortress. They impacted on the ground along with Raiku's staff, which broke off in half as Korra noticed something between the two halves of the staff.

Korra stared down at the betrothal necklace, then back at Raiku's unconscious form. "You were going to..." she trailed off, hearing a groan come from Raiku as she placed the necklace back inside his staff

"We were not prepared for that."

"No we weren't. You okay?"

"Yeah. That woman... she-"

"I know. She was powerful. Even powerful than me."

"Looks like this Harbinger thing gets more involved than we ever thought. Where are we anyway?" Raiku asked, as Korra's hand lid on fire show where they currently were

"I think we're in the catacombs underneath the fortress." Korra stated. "These look like they haven't been used in a long time."

"Surprised we ended up here to begin with and survived that confrontation."

"Let's find a way out and regroup with everyone."

Campsite

The wandering duo continue on forth, searching for a way out of the catacombs. Forty stories below filled with abandoned graves of those that protected and served the White Lotus. There were insects crawling on deserted skeletons and the roar of the dragon echoing out through caverns. Korra narrowed her eyes to glimmering light, spotting the way outside the cave as her and Raiku. They venture out of the cave, flakes of snow hitting their faces as they covered them except for the eyes while dragging their feet from off the snow. For a few hours, they have been walking through winter storm until their feet eventually started to wore down. The last thing they heard before kneeling in the snow was a sudden screech by a creature with a pair of familiar wings, as their eyes closed while fading into a state of unconsciousness. Both Raiku and Korra felt the feeling of sudden warmth over their bodies as their eyes slowly opened.

"Korra! Raiku!" Bolin exclaimed as he roped them into an embracing hug. "Am I glad to see you two awake!"

Mako grinned as he let the tent open for a bit. "They're up." he shouted out

"Where are we?"

"At a temporal campsite. Good to see you two made it."

"Everyone got out okay?"

"Some of the refugees got out safely, but most of the White Lotus guards from the temple."

"What happened to you two?" Tenzin asked

Korra sat up on the cot she rested. "That woman, Fisuili. She happened. She's something called a Harbinger and she knows Avatar Wan."

"How is that possible?" Mako asked

"I don't know. That's something I have to talk to Wan about. But not right now."

Tenzin understood nodding his head. "I understand. We'll give you two a moment to yourselves."

"Thank you." Tenzin along with Mako and Bolin took their leave as the hyena spirit Aye-Aye suddenly appeared in front of them. "Aye-Aye."

"It is good to see you two are alive." Aye-Aye said genuinely as he stared at Korra. "Your encounter with Fisuili must have difficult. To be honest, I was not expecting her."

Korra glanced at Aye-Aye. "What do you know about her?" she asked

"She was the daughter of a powerful Harbinger equivalent to Avatar Wan during the coming of the Wudai star." Aye-Aye stated

"When Wan was the Avatar? And what is the Wudai star?"

"Yes." the hyena spirit answered. "And as for the Wudai star, it is a legendary star that comes out every 10,000 years. To the point that can enhance a bender's power."

"Like how?"

"The same way Sozin's comet enhances a firebender's ability. This would do the same to any other bender."

"But...?"

"But it can enhance a energybender's five times the power. Make them possibly more powerful than any other bender." Aye-Aye explained. "As for the whole story on how the war between Avatar and Harbinger started, that is something you should ask Wan for yourself."

"This could've been stopped. Why didn't you say anything or tell anyone about this?"

Aye-Aye moved his head down before looking up. "Because of the same reason why harbingers that converted to avatars who sided with Avatar Wan thought. Fear. Loss. Death. Those who respected and admired Myriana, stood by Wan's side in the war. Many of them did not want a repeat of it 1500 years later. Which was why they removed any knowledge of it."

"You made sure no one would ever know."

"In doing so for the betterment of both the physical and spirit world, erasing all secrets of bringing about a harbinger." Aye-Aye stated. "The only way I saw that can make history repeat itself."

"So you and Hop-Hop were the only ones that knew?"

"Only I did. If I had not cloak Fisuili and the discovery of the Harbinger, your uncle would no doubt acquire the secret. Or if any of your enemies had knew of this, they would create an entire force of Harbingers at their side."

Korra narrowed her eyes in a determined gaze. "How can I stop her?"

"You will need what he has." Aye-Aye said referring to Raiku as he pointed at the silver haired airbender. "The combat form of energybending. Either by training to reach that peak or at the very least passed on you if all else fails. We may not have time for you to fully master it."

Korra crossed her arms as she quirked her eyebrow at the hyena spirit. "You do know that I mastered metalbending in Zaofu five years ago just in the span of a few days? I can handle this. If Raiku mastered it for three years while it takes longer than most, so could I."

"That will not be easy for easy for you, Avatar." Aye-Aye stated. "This may prove to be a difficult challenge. But for now, these refugees would need somewhere safe to stay. Away from the Order's thrall and absolute rule."

"And where's that?"

Aye-Aye looked forward ahead over the mountains while he sat. "North in the Earth Kingdom." the hyena spirit stated referring to the current Earth Sovereign before getting up from the snowy ground. "There is where hope will be rebuilt and rise over fear itself."
