Shocking, I know, I updated this. But truth is, i'm sick as a dog and was going through and I suddenly started thinking of this fic and figured, why not? What else is a sick girl supposed to do? Luckily after I get past the next two I've got a really stable idea of where I'm going and have quite a bit of it written. However, don't expect a quick update. And yes, there are some things that are a bit vague but I promise they will be revealed! I may even change a bit of the chaters I don't like and make it so that they focus on answering some questions. Other wise I'm just gonna have everything answered in the end. But either way things will be answered! Don't own DP or ATLA, however I do own Sonya and Kasey.

Danny bowed as Clockwork approached him in his dream from a mist of black "Danny, Aang will go to Roku's home island to learn how the war began, you will use this time to travel with me so I can show you why I brought you here to this world" he said.

Danny nodded "Okay Clockwork" he said before turning over in his sleep.

Line break

The next day Danny sat at the back of Appa's saddle after having explained everything to Sam, Tucker, and Jazz. He smiled nervously as they neared the island "I'll meet up with you guys later" he called out to everyone.

Sokka raised an eyebrow "Where are you going?" he asked.

Danny smiled "To meet an old friend and learn about some history, you know, same as Aang" he said before going ghost and taking off.

For a moment he severely missed his glider as he knew Aang and Jazz missed flying on theirs. Danny flew above the small island before choosing to land on one of the two volcanoes. Danny sighed as he sat down, waiting for the time master to come. He smiled as his ghost sense went off "Hey Clockwork" he greeted as he turned to face the time master.

Clockwork bowed to him "Come with me" he said as the two were engulfed in a mess of clocks.

Line break

Zuko tossed and turned in his bed, not able to get to sleep. He shot up at a noise right outside of his door. He leapt up and ran to the door, seeing a person running down the hall. He went to follow them but paused when he saw a scroll on the ground.

Warily he picked it up and opened it "You need to learn the history of your grandfathers demise, it will help you determine your own destiny" he read.

He stared at in confusion for a while just standing there "Zuko?" a voice asked.

Zuko jumped and turned to face Valerie who was looking at him in concern "Are you okay?" she asked.

Zuko nodded but then caught sight of her tear stained cheeks "Have you been crying?" he asked.

Valerie winced and quickly wiped away the tears "It's nothing, just thinking about my family" she said.

Actually she was thinking of how Danny was gone and she hadn't been there to help, but he couldn't know that. Zuko then held out the scroll for her "Someone sent me this" he said.

Valerie took it and read it "It's probably nothing, didn't Sozen die peacefully in his sleep?" she asked.

Zuko shrugged and carelessly Valerie tossed the scroll onto a lantern. Zuko let out a small gasp as more writing was revealed.

Valerie grabbed it and looked closely "The ancient history resides in the Dragon Bone Catacombs" she read. Both teens exchanged startled looks.

Line break

In just minutes both Valerie and Zuko were at a temple that rested on the outskirts of the city. Valerie moved forward but Zuko stopped her, just as a sage walked out, fire bending a bit to open a secret passage. Valerie watched curiously before hearing a thump besides her.

Startled she looked at Zuko who had sat down to wait. Valerie hesitated before following his example. They waited in silence for a few minutes until Zuko finally rose, motioning for Valerie to follow him. Quietly they crept alongside each other.

Suddenly Valerie stopped and leaned towards him "Your walking to heavily. Try to avoid having you heel touch the ground, it softens the impact and actually makes you a little faster and stealthier" she whispered. Zuko nodded, doing as she said.

They raced over to the medallion that seemed to rest in the middle of the room. Carefully Zuko shot a blast of fire, opening the passage to reveal a small stair case. They quietly made their way down before entering a chamber, lined with what appeared to be dragon bones.

Valerie shivered as they traveled down the hall to a statue of sozin. Carefully Zuko placed his hand on a Fire Nation symbol on the statue's chest, delivering a powerful blast of fire. Valerie raised an eyebrow as it opened "And how exactly did you know about this?" she asked.

Zuko blushed "I had to find some ways to hide from Azula" he said sheepishly. He then grabbed a small lantern from his cloak, lighting it as they stepped inside.

The room was filled with cobwebs and dust but Zuko ignored it, moving to where some scrolls rested under a dragons head "The final testament of Fire Lord Sozin" he whispered.

Line break

Danny looked curiously at Clockwork as the clocks surrounded them "So exactly where are we going?" he asked.

Clockwork smiled knowingly "To take a look at your ancestors past" he said.

Danny felt confused, even more so as the clocks began to vanish "Turn invisible during this" Clockwork said.

Danny did so as the last of the clock vanished to reveal a lush, green courtyard. Danny raised an eyebrow at the sight of two men sparing "How is this my ancestors past?" he asked as one of the men tripped over a root.

The other man smiled "Looks like I win again Roku" one of the two teens said.

Danny gasped "Roku? Avatar Roku?" he asked.

Clockwork nodded as the teen standing held out his hand "Are you kidding?" the fallen teen asked, accepting the hand "The tree root did all the work. Nice one Sozin" he commented.

Danny felt his head start spinning "Roku and Sozin were friends?" he asked.

Clockwork nodded "The best of friends" he said quietly.

Danny then jumped as a figure leapt over the wall, swiftly followed by a girl. The young man in front looked around sixteen and had messy raven black hair that flew all over the place and looked quite matted. His clothes were gray and shabby and seemed just as tattered.

The girl behind him had the same raven hair but unlike her companion it was clean and silky and fell down her back in a cascade of beauty. Her clothes also had the same well kept appearance. Roku and Sozen paused, smiling widely at their appearance "Kasey? Sonya?" they asked.

Both teens looked up and Danny saw strange baby blue eyes that matched his "Who are these two?" he asked.

Clockwork smiled "That is Kasey and Sonya, they were kept hidden from history for many reasons that you will find out in time" he said.

Roku and Sozen quickly climbed to their feet in haste to go to the new arrivals quickly bowing to them. Roku then shot Kasey a grin "I still don't get why your so uptight about everyone knowing who you are" he said lightly.

Kasey's face became hard and Sonya looked away, clearly troubled "You'll find out soon enough" he whispered.

Curiously Danny looked at Clockwork who bowed his head "Danny, as you can see they were all friends and shared many things. Sozin and Roku even shared a birthday" he said lightly.

Danny smiled slightly as clocks surrounded them to reveal some people at a celebration. Danny smiled, the emotions quite uplifting. Suddenly Roku's gaze caught a young girls and he stumbled, Sozin barely catching him in time.

Sozin laughed at his clumsiness and Danny couldn't help but grin. But the mood became somber as a group of Fire Nation sages entered, approaching the two. A worried expression crossed Sozin's face as he hurried down "Did something happen to my father?" he asked in concern.

Danny raised an eyebrow, this was the guy who would wipe out an entire nation? However one of the sages shook his head "No, Prince Sozin. We are not here for you. We are here to announce the identity of the next Avatar" he said wisely.

Roku and Sozin exchanged startled looks as the sages turned to Roku "It is our honor to serve you, Avatar Roku" they said, bowing. Danny raised an eyebrow as people began bowing to the shocked teen. However movement caught his eye and he looked in surprise to see Kasey and Sonya exchange worried glances, bowing hesitantly.

Line break

Zuko paused, looking at Valerie who shrugged. He then looked down and continued reading aloud "Soon the day came when my friend Roku had to leave the Fire Nation and face his destiny as the Avatar. But before he left I had made one last point to visit him and was surprised to find him talking to our good friends Kasey and Sonya. It was then we found out something strange…."

Line break

Roku looked curiously at the two raven headed teens in front of him "What did you two want to talk about?" he asked.

Danny stayed silent, watching as Sozin crept down the hall, stopping outside his door. Kasey side, running a hand through his messy hair "Well, as the Avatar we must inform you of a well kept secret" he said.

Roku frowned "Is this dangerous?" he asked quietly.

Sonya laughed, her voice almost musical. Danny saw Sozin's face light up in a strange blush "No" Sonya replied "It's about the Avatar though and so it's in your best interests" she said lightly.

Roku nodded and Kasey sighed "Along with every Avatar there is a second and third Avatar that pretty much aren't important to history. For the most part they've only come out once and that was to stop the land from flooding. They only exist to help the Avatar but only if needed" he explained.

Roku looked at him in surprise before his gaze shifted from him to Sonya "Are you two the other…Avatars?" he asked hesitantly.

Sonya nodded "Yes, and we are duty bound to protect you but only if the need arises. But if any one asks, I'm a water bender and Kasey here is a fire bender. It's our natural elements" she explained.

Suddenly Sozin walked in "But aren't you twins?" he asked.

The two appeared startled before Sonya smiled "Yes. Our father if a Fire Nation civilian but our mother is a healer from the Northern Water Tribes. She was trying to get a sense of belonging" she said.

Kasey however looked at Sozin with a hard look "You heard, didn't you" he said quietly.

Sozin ignored him, turning to Roku "So how come you haven't packed?" he asked.

Roku lowered his head, depressed "I started packing but then the sages told me I would no longer need any worldly possessions" he said.

Sozin immediately sobered "oh…" he said.

Sonya shrugged "You get used to the fast pace" she reassured.

Sozin then smiled, removing a small crown from his top knot "Here. I hope you're at least allowed to have this" he said, holding out the crown.

Roku looked at it in surprise "But this is a royal artifact. It's supposed to be worn by the crown prince" he said.

Sozin shook his head, offering the head piece "I want you to have it" he said. Roku smiled at him, accepting the gift and placing it in his hair. The two friends stood, bowing to each other.

Sozin then turned to Sonya "I take it you two have to go with?" he asked.

Sonya nodded sadly "We won't necessarily be with but we will be shadowing him. I hope we see each other again soon though" she said quietly.

Sozin nodded and the two moved forward, hugging each other "Hopefully it won't be to long" he said.

Sonya didn't answer but lingered in his arms before pulling away "We should get going" she said quietly. Danny looked at Clockwork who pressed a button on his staff.

They were instantly surrounded by clocks and Danny smiled as they appeared above the earth a small group of scenes passing under them "Roku left the Fire Nation and worked hard to master each of the elements. He started at the Southern Air Temple before moving on to the Southern Water Tribe, and finally the Earth Kingdom. Sonya and Kasey shadowed him dutifully before finally, they had all mastered all of the elements and joined each other" he said.

Danny watched in awe as Roku, Kasey, and Sonya all moved in unison, casting out all four elements in one attack "And after many years of work they finished, they were all fully realized Avatar's" he said. The scene then smoothly faded and Danny blinked as he found himself in the Fire Nation once more.

It appeared to be a throne room. An older Sozin sat on a throne as Roku followed, Kasey and Sonya flanking him on either side. Roku smiled cheerfully "Sozin, or should I say, Fire Lord" he commented, happy for his friend.

Sozin's face remained blank "Customarily, my subjects bow before greeting me, but you're the exception" he said, his blank face melting into a smile as he walked over to Roku and the two embraced each other.

Danny's eyes softened "Even after all that time he didn't change" he said quietly.

Clockwork nodded "They were still best friends, and not only that, they were each others best man" he said. The picture faded once more to reveal a wedding.

Danny couldn't help but smile upon noticing it was a double wedding. Besides Roku stood a hazel eyed young woman and besides Sozin stood Sonya. Danny couldn't help but smile "Wow, the Avatar and the Fire Lord. Who knew" he said softly.

In the back of his mind he truly began to doubt Sozin's participation in starting the war. However after a moment Sozin leaned over and whispered something to Roku. They both looked to their new brides who nodded, scooting closer to talk as their husbands left.

Danny looked curiously at Clockwork who nodded. The two followed as Sozin lead Roku to a balcony. Sozin halted and frowned "I've been thinking hard about the state of the world lately" he said seriously.

Roku smiled "Sozin, it's our wedding. Have a dance with your new wife and lighten up" he said.

Sozin sighed "I know, I know, but just hear me out. Right from the start, I was destined to be Fire Lord. And although we didn't always know it, you were destined to be the Avatar. It's an amazing stroke of fate we know each other so well, isn't it? Together, we could do…anything" he said breathlessly.

Roku frowned "Yeah…we could" he said in slight concern.

Sozin looked out on the Fire Nation from where he stood "Our nation is enjoying an unprecedented time of peace and wealth. Our people are happy and we're so fortunate in so many ways" he said proudly.

Roku began to shift uneasily and Danny fidgeted a bit, feeling the uneasy atmosphere "Where are you going with this?" Roku asked, clearly getting concerned.

Sozin turned to him "I've been thinking. We should share this prosperity with the rest of the world. In our hands is the most successful empire in history. It's time we expanded it" he said.

Roku's eyes widened in realization and Danny's heart fell. The remainder of the argument fell deaf on his ears. So that's why Sozin attacked the nations. To share peace and prosperity?

Danny felt sick and Clockwork placed a hand on his shoulder, clocks once more surrounding them "Roku left after that and thought nothing of it. During that time Sonya had her first child, prince Azulon. But despite that peace Sozin went ahead of his plan, and Roku found out and chose to confront him" he said.

Danny looked down as the clocks vanished. They were floating above the throne room as Roku burst into the room, looking infuriated "I've seen the colony, Sozin. How dare you occupy Earth Kingdom territory!" he said angrily.

Sozin looked at him bitterly "How dare you, a citizen of the Fire Nation, address your Fire Lord this way. Your loyalty is to our nation first. Anything less makes you a traitor" he said, his voice deadly calm.

Danny could feel his shoulders shaking in anger but stopped as the doors opened again and Kasey entered, closely followed by Sonya. Sonya's eyes were puffy but she stood strong "Don't do this Sozin" she said, her voice calm.

Sozin glared at her "If you were loyal to me then you would see this is for the best" he hissed.

Sonya shook her head "I am loyal to you. But it is my duty to be loyal to the Avatar first, which is Roku in this case" she said quietly.

Uncontrollable rage crossed Sozin's face and he moved up, launching a powerful and deadly blast at the three who watch calmly. Danny held his breath as the flames vanished, the three nowhere in sight. Suddenly Roku, Kasey, and Sonya burst out of the ground, using air bending to send Sozin flying across the room.

Kasey wasted no time, using earth bending to raise a pillar towards the ceiling, lifting up Sozin by the back of his shirt. The three then focused, closing their eyes. Danny shivered as their eyes opened again to reveal a strange glow as everything flashed.

Danny covered his eyes from the explosion and when he opened them he saw Roku approach Sozin soberly "I'm sparing you, Sozin. I'm letting you go in the name of our past friendship, but I warn you, even a single step out of line will result in your permanent end" he said.

He then turned to Kasey and Sonya, motioning for them to follow. Sozin met Sonya's gaze for just a moment before she turned away, he heart heavy as she walked away from him.

Danny turned to Clockwork who avoided his gaze "Sonya left with a heavy heart. She still loved Sozin but her duty forced her away. She left Azulon with him and joined Roku and Kasey at Roku's home, living in their small town for twenty five years. And they would have continued living there if disaster hadn't struck" he said.

Danny looked down as a volcano began erupting, the villagers fleeing. Danny flinched as Roku, Sonya, and Kasey stayed back. Quickly they moved in, fighting to keep the volcano under control. Danny watched with bated breath as they fought the volcano.

However as they finally managed to stop it the one next to it erupted. Danny felt a sinking feeling in his heart as Sozin joined. The four of them fought the volcano with skill and Danny couldn't help but smile, Sozin still had a sense of loyalty in him after all.

Suddenly the volcano seemed to explode with energy and lava began hissing angrily, narrowly avoiding the four. Danny stared in dismay as the four figures battled against the volcano.

With a worried glance he turned to Clockwork "Any way I could help? I can't just stand by and do nothing" he pleaded.

Clockwork frowned "You may help but only Sonya and Kasey can be saved, if you save Roku then the balance will break out of place and the Avatar will cease to exist forever" he told Danny strictly.

Danny nodded "As long as I can save at least two of them" he told the elder time master, though guilt hit him like a wrecking ball.

Without a further word Danny swooped down out of the sky and focused on creating a snowball ecto blast. However instead of the snow whirling around his hands small grains of sand built up to become a sand blast.

Danny smirked as he threw the blast down to collide with magma that nearly hit Sonya. Sonya whipped around in shock and stared at Danny with wide eyes as the others turned to him as well. Danny's eyes narrowed "Less looking at me, more fighting the natural disaster!" he cried as he used air bending to freeze some of the magma.

Quickly the others did as was told, although Sonya and Kasey had distinct frowns on their faces. Danny ignored them as he used his air bending to freeze the magma in many different ways to help it flow away from the village.

Finally they managed to get it to a decent extent but could do no more. With a sense of panic Danny turned to them "We have to retreat!" he shouted.

They nodded and the four followed him down the side of the volcano, swiftly blowing away toxic fumes that rose up from the ground. Unfortunately one of those fumes erupted into Danny and Roku's faces. Danny stumbled back in shock, his vision becoming slightly blurry.

Panic began to hit him as hot lava began to bear down on them. With sluggish movements Danny stumbled over to Kasey and Sonya who were looking at him in shock. Soundlessly Danny grabbed their wrists as Sozin took off on a fierce looking dragon.

Danny felt the cool sensation of intangibility flow through his body and the two people beside him just as the lava made contact, completely burying Roku and his dragon Fang who had circled his master. Danny quietly rose above the ground with the two as the rock hardened and cooled at an abnormally quick pace.

Once on the surface he released the intangibility and the two figures dropped to the ground as Danny lay there, coughing harshly from the toxic fumes that he had breathed in. Both figures stared at him, expressions torn between concern and hatred "Who are you? Why didn't you save Roku?" Sonya asked angrily.

A voice above them sighed "Clockwork?" Danny wheezed, his voice sounding weaker than usual.

With a groan he felt his power fading and a blinding light startled the two as Danny unwillingly turned back into Fenton "Who are you?" Kasey asked.

Clockwork then appeared above then, his expression showing pity for Danny "Young Kasey and Sonya, this is the next Avatar after you Kasey, I am a spirit of time and brought him here for two reasons, to show him how this war began and to allow him to save the two of you" he told them.

Both shot a wary glance at Danny who still lay on the ground coughing harshly "Why not Roku? And why us? Why are you even here?" Sonya asked.

Danny smiled weakly "To save Roku would have thrown off the future, I had to save you two to ensure that the Avatars all appear at the right time, we only know one though" he said.

Kasey raised an eyebrow "You?" he asked.

Danny eyes widened "No, I'm just here because I am" he said hoarsely.

He let out another hacking cough while Clockwork turned into a kid and floated over to Danny "Actually Danny you are, the second Avatar, the future life to Kasey and protector to Aang" he said.

Sonya looked at him cautiously "Who's Aang?" she asked.

Danny smiled, before coughing again "Aang is the Avatar in the future, Sozen is going to launch a war but with out Roku you can't do a thing, Aang is destined to stop the war" he said weakly.

Kasey looked down "I guess we have to go into hiding…huh?" he asked distantly.

Clockwork nodded "Yes, and don't worry, your lives will be peaceful" he told them. Clockwork then looked upwards with a frown and Danny followed his gaze, meeting Sozin's gaze. Sozin frowned and looked angrily before looking at Sonya before his face softened and he vanished.

Line break

"It hurt to lose Sonya, who vanished after Roku's death but I tried not to focus on it. With Roku gone, and the great comet returning, the timing was right to change the world. I know the next Avatar would be born an air nomad. So I wiped out the air temples. But somehow, the new Avatar eluded me. I waster the remainder of my life searching in vain, for both him and my beloved Sonya. I know both of them are hiding out there but I can only hope that someday the Fire Nation can find the Avatar. I know he's hiding. The Fire Nation's greatest threat…the last air bender" Zuko finished solemnly.

Zuko then looked puzzled "That can't be it, where's the rest of it?" he asked.

Valerie looked down "I don't know. But I must say, I don't think I've heard of Sonya or Kasey" she said.

Zuko shook his head, his eyes narrowing "Neither have I" he said quietly.

Line break

Later that night Zuko and Valerie crept through the streets towards the prison. Valerie however stood back as Zuko angrily walked up to his uncle "I don't know how you did but somehow you were the one who gave me this note" he accused, holding the note in his hands.

Iroh remained silent as usual "You said to read it to find out how my grandfather died but he was still alive in the end" he said, his tone desperate.

Valerie felt a sense of hopelessness wash over her "No…he wasn't" Iroh said.

Valerie stared in shock, Iroh talked…it was the first time he had talked since his capture, or at least to someone other than her "What do you mean?" Valerie asked.

Zuko stared at Iroh "Prince Zuko you must remember that you have more than one great grandfather, yes Sozen is your fathers grandfather…but your mothers grandfather is Avatar Roku" he stated.

Zuko sunk to his knees in shock, not knowing what to say. Iroh slowly got up and walked to the back of his prison "It is the reason good and evil are always crowding around inside you" he stated.

Zuko looked at his uncle "Did Kasey and Sonya have children? Besides Azulon?" he asked.

Iroh smiled as he removed a brick, revealing a wrapped package "Kasey and Sonya went their separate ways, but both somehow vanished from this world. I managed to talk to someone however who said they were taken to another place, a world entirely different from ours. One that our young fire bender here comes from" he said.

Valerie gasped "Are you serious?" she asked.

Iroh sighed as he walked towards Zuko, a cloth wrapped around something in his hands "The only bad thing is, the second and third Avatar's are passed down through family" he stated cautiously.

He carefully unwrapped it "I don't quite know if any of your friends are who we need but we must have hope. Perhaps the world doesn't need them and can deal as long as it has the proper leaders" he said quietly as he unwrapped the item.

The two stared in shock, somehow Iroh had gotten a hold of Roku's headpiece "Take this Zuko, it is a royal artifact to be worn by the crown prince" he told him.

Line break

Danny let out a gasp as he landed on the rim of the volcano one hundred years later "Are we back?' he asked weakly, the poison was starting to make his head spin.

His vision had already become a total blur. Clockwork frowned "Danny when you did that sand blast, that was a new ghost power and because it dealt with earth that unlocked your earth bending, you are to tell only Tucker of this and he is to teach you earth bending in secret" he explained.

Danny nodded weakly "If I make it long enough to get to them" he wheezed.

His breath was becoming shaky and with tender hands he could feel Clockwork lift him up. A breeze fluttered in his hair and he distinctly heard voices draw near "I'm telling you it was Danny, but he looked in bad shape" Aang was saying desperately.

Danny could feel Clockwork lay him on the ground and whistle. Footsteps distantly seemed to rush towards him "Danny!" Jazz shrieked.

Danny weakly highered his gaze to meet hers "Poisoning, please help" he whispered before falling unconscious.

Preview:

Tensions are high and friendships are tested as Toph begins participating in scams to get money. But with most of the gang backing her up can Danny, Katara, and Jazz show them that it's not smart? Or will Toph just get them into even more trouble? Danny groaned, looking up as Combustion Man approached him "Toph you are so dead" he muttered under his breath. Hopefully they can get out of this in one piece!

Story fact:

In the series it was just Aang and Zuko who went on this parrellel adventure into the past. And also Sonya and Kasey didn't exist. They were added in for some extra flavor to the story.
