Korra POV
'Looks like this is where it ends huh? I'm sorry mom and dad, I won't be coming home today, and I'm sorry Tenzin we couldn't save Jinora' I closed my eyes as Unalaq came closer, I had no energy left, not even enough to earthbend a small pebble or to shoot a little fire at him. I waited for the final strike, but it never came, instead the sound of ice forming a lightning crackling filled my ears, I opened my eyes. "Nice to meet you Ms. Avatar, unfortunately you won't be dying today, a joy.". The first thing I noticed was a man standing in front of me, he had deep red hair that was tied into a messy bun and a very not Unalaq face.
Third Person POV
Kurenai could be seen standing in front of the Avatar with a playful smirk, "I suggest you get Raava and get somewhere safe Ms. Avatar, things are about to get a little messy." he said. It took a while for those words to sink in for the Avatar but once they did she picked up the small Raava and ran off to her friends. Kurenai could be seen given a soft smile but it immediately disappeared as soon as he heard the idiot who released his dad shouting. "WHO ARE YOU!" shouted the idiot, "I'm the only long haired bastard that has the privilege to piss off Vaatu is who I am!" replied Kurenai. A wave of water was sent his way, so he channeled energy into the ground and a wall of vines sprouted up to protect its master. Once the wave of water passed by, Kurenai immediately jumped back as a flurry of icicles tore through his vines, unfortunately for him more icicles formed from the puddles left by the waves, in a show of speed and agility he managed to dodge the storm of icicles coming his way, once the coast was clear Kurenai retaliated with a flurry of flames, but not just any flames, blue flames.
Unalaq was taken aback by this discovery but quickly shook of his surprise in favor of dodging his opponents strikes. Unfortunately for him the flames were much much quicker then he anticipated, leaving his clothings singed and him with minor burns. Unalaq had no time to voice his thoughts however, due to a huge torrent of flames coming his way, with no possible route to escape or dodge, he quickly put up a dome of ice and prayed to the spirits that it would keep him alive.
The Avatar and her friends were left in utter shock and amazement, not only did this guy have blue flames like a certain murderous princess, but he had skills that could rival said murderous princess! Hopefully those are the only things the two had in common.
Kurenai POV
"Come on, can't you just die already" I whined, forgetting that there was an audience. I immediately turned around and cleared my throat, "The name's Kurenai Shin, 'Son and Avatar of Vaatu' blah blah blah, nice to meet you avatar, scarf boy, and ferret breath" faking a polite introduction. I could see them flinch at the 'Son and Avatar of Vaatu' part with scarf boy and ferret breath getting annoyed with the nicknames I so graciously gifted them. I gave them a playful smirk and turned my attention back to the idiot, "So you going to come out or do you want to get cooked in there, I have all day to do this" I yawned, after waiting for a few minutes I got annoyed and just blasted lightning at him.
I could hear the gasps from the Avatar and her group while I searched through the debris looking for him. "Well I'll be damned he's gone" I said in surprise "That's one win and one loss then huh" I hummed out loud. I walked over to the group and sidestepped as a ball of flame came my way courtesy of the Avatar, "Stay back!" she shouted "I really don't think that's how you should treat someone who saved you and your friends" I said with a raised eyebrow. Right before she sent a couple of boulders my way I restrained her with my vines, "Let me introduce myself once again, the name is Kurenai Shin 'Son and Avatar of Vaatu' and no neither my dad or I are planning to kill you, so what're your names?" I asked.
Third Person POV
"My name's Bolin, and that guy right there is my brother Mako, and that's Korra you have trapped in your vines" nervously said the now introduced Bolin, "Why should we believe you, for all we know you and Vaatu could just want a way out of here and plunge the world into ten thousand years of darkness" shouted Korra while fighting against her restraints, Kurenai sighed at the Avatar, "Well then, there's this girl we saved a while ago wearing airbending clothes, is she one of your companions?" asked the son of Vaatu, "Where is she! Where did you take Jinora!" shouted the Avatar. "Oh shut it Avatar. I saved her from the "Fog of Lost Souls", and she's right here" as Kurenai said that, a rather large vine was seen speeding towards the group with a familiar looking orange and yellow package sitting on top, once it got there the now named Jinora got off and ran towards the group, "Korra!" shouted Jinora while trying to hug the vine wrapped Avatar. "Yes well the reunion is great and all, but I'm sure I've shown you neither my father or I are the bad guys. So can we please just get out of here, I've been dying to see this Republic City" said an exasperated Kurenai as he released Korra from her bindings.
"Fine, but if you or Vaatu try anything" Korra left that threat hanging, but Kurenai was not even slightly bothered which one could tell with his eye-roll at the supposed threat.
As the group walked towards the portal Bolin decided to try and break the ice "So uh blue fire, how'd that happen?" he awkwardly asked, Kurenai hummed in thought before giving his answer "Much like Princess Azula my fire was fueled completely by pure hatred, thus making them blue." he replied in an even tone "What did you hate?" probed Mako, once again Kurenai hummed in thought before answering "Lot's of things, my birth parents for example, certain spirits, the world, so on and so forth really" he vaguely replied, "Your parents? Didn't you say Vaatu was your dad?" furthered Korra "He's my adopted father, my birth parents abandoned me somewhere near that tree and Vaatu merely picked me up and raised me" replied Kurenai as stoically as possible, "How did they even get in the spirit world?" once again asked Korra "Do you still hate them?" asked the now introduced Jinora, Kurenai closed his eyes and took a deep breath "I don't know how they got here and frankly I don't care, as for your question Jinora, no, I no longer hold any negative feelings towards them, if they didn't drop me off here then I would've been a different person, and I quite honestly like this current me." he finished with a small smile.
While the group of humans were talking high above Raava and Vaatu were having their own conversation, "What's your angle Vaatu?" calmly asked the smooth feminine voice of Raava "I have no angle dear, I've lost interest in plunging the world into darkness, I'm only interested in fulfilling my son and I's goal" replied the spirit of chaos and darkness, "That goal being?" questioned the spirit of order and peace "Why, traveling the world of course, there's enough chaos and darkness already so we plan on just seeing the sights" stated Vaatu in a soft voice. The two spirits continued the walk in silence with Raava having many things to think over.
"Here we are, the Northern spirit portal thank you all for visiting the spirit world and I hope you all plan to visit again" said a sarcastic Kurenai as Korra and her group passed by, Vaatu shrunk down in size and landed on his son's shoulder, what could he say being stuck for ten thousand years give makes one quite lazy no matter how powerful, Kurenai gave his father a smile "Life's about to get a whole lot more interesting" said an enthused Kurenai as he walked through the portal.
