Author's Note: After an unamnious vote at Devianart from the fans who read this story over on that site, I've decided to post this story up on . This story is basically all three seasons (and more) of TFA but set in the Warriors book series universe. In the Warriors book series, the characters are cats who live in four Clans- ThunderClan, RiverClan, ShadowClan, and WindClan- in the forest and hunt and fight. Each clan has their own leader, deputy, and medicine cat. Sometimes the Clans fight among themselves, but they try to live in peace by following the Warrior Code. The rest will easily be explained in the story.

Anywho, about fifteen chapters have already been written out and are up on Devianart, as well as many, many sketches and pictures from the story, so go check it out on my profile if your interested (I have a picture of Warrior Bumblebee already on my profile). Anywho, I hope this story will be just as popular on this site as it is on Devianart. Like with my other current story, The Princess and the Spider, this will be updated weekly. Enjoy!

Prologue

A full moon lit the dark skies, shedding its light upon Fourtrees, revealing the four towering oaks that stood guard upon the clearing in the middle of it. The only sound that could be heard was the wind softly rustling the oaks' leaves and the flow of the river but besides that, the night was silent. One would hardly be able to tell that a storm was brewing deep within the forest and, on this night, Fourtrees would become a place blood and darkness.

Shrieks and screams began to fill the once still air as dark forms leaped and tore at each other. Blue eyes glared at red and gleaming claws met head on with white, sharp fangs, splashing the grassy clearing with red blood.

For once, the cats of all four forest clans- ThunderClan, RiverClan, ShadowClan, and WindClan- were fighting not against each other, but side by side, fighting against one enemy. One cat who had betrayed all four clans, even the one of birth, and now threatened to destroy them all with his BloodClan cats in one ambitious, evil effort to rule over all the forest.

Amidst the screeching, battling cats, one cat stood out above them all as he stood alone on top of Great Rock. He was a large, blue and white long-furred cat with solemn blue eyes that searched through the frenzy of cat with great intensity.

"Traitor! Traitorous piece of fox dung!" The blue and white cat hastily jerked his head in the direction of the enraged shrieks. "You BloodClanners will pay, Starscream!"

A golden-furred WindClan she-cat was being pinned to the ground by a vicious looking BloodClan cat with red, black, and purple marking. With a furious growl, the blue and white tom leaped from Great Rock right onto Starscream's back. He bit down deep and hard into the BloodClan's shoulder.

Starscream let out a screech of pain and reared up, knocking the blue and white cat off and spraying speck of blood along the ground. The golden Windclan she-cat hissed and batted Starscream across the face with her claws. With one last snarl, Starscream turned tail and fled from the pair. The golden she-cat turned and stared at the white and blue cat with gratitude in her blue orbs.

"Thank you, Ultra Magnus." the small yellow-furred she-cat thanked the leader of ThunderClan.

"It was nothing, Goldbug." The ThunderClan leader meowed, giving the small WindClan warrior a curt nod.

"Goldbug! Goldbug!" Both cats turned to see two new cats coming towards them. One was a gold tom with black spots all over his pelt- Cheetoh, mate of Goldbug- and the other was the white-furred leader of Windclan- Prime Nova.

Cheetor came to a halt in front of Goldbug and pressed his scarred muzzle against hers. "I saw you with Starscream and I thought…." He was cut off by his mate's soft purring. "I'm fine, Cheetor, you stupid furball. I had some help from Ultra Magnus."

"So we saw." Came Prime Nova's low growl. The white WindClan leader glared darkly at the ThunderClan leader. "Next time, watch out for your own warriors. Ultra Magnus."

Ultra Magnus narrowed his eyes. "Only if you look after yours."

Prime Nova hissed and turned to his two warriors. "Get back to battle! No clan of traitors and rogues is going to take over our forest!"

Goldbug gave her leader a nod and darted back into the mob of fighting cats. Cheetor turned to follow her but not without giving Ultra Magnus a grateful glance. "Thanks." The cheetah-pelted WindClan warrior murmured before following his mate into battle.

"Ultra Magnus! Prime Nova!" The leaders of the other two forest clans fought their way towards the WindClan and ThunderClan leader.

"Has Megatron been found yet?" The new leader of RiverClan, a young red, yellow, and orange furred cat called Rodimus Prime asked the other two leaders. Both Ultra Magnus and Prime Nova shook their heads.

"No, we haven't seen him." Ultra Magnus meowed.

"He has to be close." hissed the ShadowClan leader, a sleek black-furred she-cat named Prima. She swished her tail in agitation. "His disgusting scent is everywhere. All this will end only when he is dead or driven off." She glanced over at Ultra Magnus with knowing eyes. "You do know this, Ultra Magnus."

The Thunderclan leader nodded, determination swiftly covering up the sad gleam that was in his eyes a moment before. "I know this as well as you do, Prima. I will do it myself if I have to."

The ShadowClan leader nodded in approval while Rodimus and Prime Nova gave each other uneasy glances. This battle was the worst that the forest had ever seen. Cats of both the forest clan and BloodClan were being slaughtered on all sides and grass beneath their paws was sticky with blood. Warriors were dying all around them. Already Smokescreen of ShadowClan and Inferno of ThunderClan laid dead nearby, both killed by Nightbird and Bonecrusher of BloodClan. How many warriors needed to fall before all this was over?

Suddenly a loud yowl filled the air and Ultra Magnus' eyes grew wide with horror. "Ratchet!" Without a moment of a hesitation, the ThunderClan dashed forward, fighting his way towards the edge of the four oak trees with the three leaders' right behind him. Ultra Magnus came to a halt at the edge of Fourtrees and gazed into the shadows, fur bristling.

Dark clouds began to gather overhead, sending the first raindrops raining down upon clearing as Ultra Magnus at last found what he was looking for. Half hidden beneath one of the bushes was an old red and white cat. He was crouched protectively over a wounded cat, his fangs bared and his eyes flashing at hidden enemies that dared to come near.

Ultra Magnus took a pawstep forward, relief filling his eyes as the sight of his medicine cat. "Ratchet! You're alright!"

The old cat jerked his head in shock at the sound of his leader's voice. To Ultra Magnus's surprise, horror filled hid friend's eyes. "Get back! He's here!"

"Who's here?" Ultra Magnus' question was answered by a cold, dark voice.

"Greetings Ultra Magnus."

Thunder boomed in the dark skies above and the light shower of rain became a full storm. Both Ultra Magnus and Ratchet whirled around at the sound of the menacing voice. From the shadows, a figure slowly slid out. Though the skies were dark, the cat's glowing red eyes shone through the shadows, filling both cats with horror and dread.

"Megatron." hissed Ultra Magnus, crouching down in a battle stance, his fur bristling with defiance. "Do you really believe that your army of traitors and rogues will defeat us?"

The leader of BloodClan, a large grey, black, and white cat, stood tall in the pounding rain, glaring down at Ultra Magnus with the merest hint of a sneer on his face.

"I believe that that answer speaks for itself. Look around you, foolish forest cat." Megatron swept his tail in the direction of the clearing where sounds of battle could be heard over the storm. "Soon there shall be no ThunderClan left for you to rule. No RiverClan. No ShadowClan. No WindClan. Only BloodClan shall rule over the forest with me as their leader!"

"Over my dead body!" Ultra Magnus spat. Behind him, Ratchet hissed in agreement while still tending to his wounded apprentice, Wheeljack.

A dark smirk spread across the BloodClan leader's face. "For once, we were thinking the same thing." Without warning, Megatron leaped, his fangs bared in a horrible roar. Ultra Magnus jumped to one side, but as Megatron landed, he sharp turned and latched out one forepaw. His long claws managed to catch Ultra Magnus by the haunch and pulled him down. Megatron was on top of the ThunderClan leader in an instant, pinning him down by the neck. Though Ultra Magnus batted Megatron's sides with his back claws, the evil cat's grip held firm.

"No! Ultra Magnus!" Ratchet leaped forward to defend his leader but one kick from Megatron's hind legs knocked the old medicine cat away.

Pressing down heavily upon the ThunderClan leader's neck, Megatron leaned close to his ear and whispered to him in low, menacing voice.

"How does it feel, Ultra Magnus? Leading not just ThunderClan to their deaths, but the other three Clans as well? How does it feel knowing that StarClan has abandoned you to feel death's grip?" His eyes narrowed into glowing red slits. "How does it feel," he hissed in Ultra Magnus' face. "knowing that you are about to be overpowered by your own son?"

"You shall never win, Megatron!" Ultra Magnus snarled, still struggling to escape the dark cat's bounds. "The four forest Clans shall never be defeated by BloodClan!"

Megatron let a chuckle rumble in the depths of this throat as looked down at the defeated leader. "Don't you get it, you old fool? I have already won!" With that, the BloodClan leader raised his paw finish Ultra Magnus off.

Ultra Magnus squeezed his eyes shut, waiting for the death blow to come. Suddenly yowls and screeches filled the air upon him and he felt the weight of Megatron fall from his neck. His eyes shot open and he stared in shock at the scene unfolding before him. All three Clan leaders- Rodimus of RiverClan, Prime Nova of WindClan, and Prima of ShadowClan- were fighting side by side against Megatron. Though he fought with the strength of TigerClan, there was no way that Megatron could win a fight between three Clan leaders. The BloodClan leader was cornered by the three.

Ratchet gently helped Ultra Magnus to his paws and the two made their way towards the other leaders. Soon all five cats were circled around Megatron, claws unsheathed and fangs bared, ready to take on the BloodClan leader together.

Megatron snarled and jerked his head side to side, glaring daggers at each leader, trying to find a way to escape. Ultra Magnus took a pawstep towards the BloodClan cat, his blue eyes as cold as a winter storm.

"You are defeated, Megatron. Call your BloodClan cats off and leave for this forest and we'll let you live. Don't and we'll end all nine of your lives here and now." The other three leaders nodded in agreement.

Megatron bared his fangs at the forest leaders and hissed in defiance. His red eyes were burning pits of hatred as he gave them all one last glare and lifted up his head and yowled in the skies.

"BloodClan! Retreat!"

Instantly, the sounds of battle turned into the sound of surprised screeches and the sound of retreating BloodClanners. Victorious cries rang up from the forest cats. Slowly, Prima and Ultra Magnus moved to allow Megatron to escape their binds. The BloodClan leader padded away with his head held high, his steps never faltering as he reached the edge of Fourtrees. Only then did he turn to face the four leaders. Ever Prime Nova was disturbed by the depths of loathing in his fiery red eyes.

"Enjoy this victory, forest fools." Megatron growled as the last raindrops fell and the dark clouds began to drift away. "For it will be your last. BloodClan shall strike again and when it does, the entire forest shall tremble and fall. We shall make the blood of all your cats flow and turn the river red! We shall return and I, Megatron, shall rule over all!" With that, the dark cat melted into the shadows of the forest, leaving no trace that he had even been there before.

"At last," Prima mewed, "it is over."

"The four clans rule the forest once again!" came Rodimus' victorious meow. He alone, didn't seem fazed by Megatron's dark words.

Prime Nova stood up and gave each leader a curt nod. "The truce is over. It is time for us to return our warriors home to heal."

The WindClan leader's words seemed to shake Ultra Magnus out of his state of shock. The ThunderClan leader gave his head a shake and blink grateful at each leader. "Thank you all and may StarClan watch over you."

As the other leaders mewed their good-byes and left to gather their warriors, Ratchet quietly padded up to his shaken leader. "Are you alright, Ultra Magnus?" He asked.

Ultra Magnus shook his head. "Do not concern yourself with me." The noble leader stood up. "Come. Let's go return our warriors home."

Ratchet nodded and signaled for his apprentice, Wheeljack, to hurry along. The old medicine cat lifted his head to the night sky, the stars now visible with the storm cleared. He sent a prayer of thanks to StarClan that all the clans had made it out of this war okay.

Suddenly, to Ratchet's surprise, one of the stars burst into a infernal of white fire that shot through the skies like a comet. Faster and faster it fell until it disappeared across the treetops and behind the horizon, towards the TwolegPlace. A soft, haunting voice echoed inside Ratchet's mind.

"The Power of the Stars shall fall and bind four into one. Sky shall fill with blood and one paw shall hold all."

"Ratchet, are you coming?" squeaked Wheeljack, staring at his mentor in confusion.

Ratchet shook head and took his gaze away from the star-filled skies to stare at his apprentice in shock. "Didn't you see that?"

"Wheeljack tilted his head to one side in confusion. "See what?"

"See what? The light in the sky, you dimwit!" Ratchet growled. Wheeljack squeaked in fright and rapidly shook his head. "No sir!"

Ratchet slowly followed his leader and apprentice back to the ThunderClan warriors, his mind in a whirl of confusion. Was what he heard and saw really a message from StarClan? A prophecy even? If so, then what did it mean? Was danger really coming to the clans once again even after all this?

"StarClan, what do you have in store for us?" Ratchet whispered, lifting his gaze to the stars above.

The stars only blinked in silence.
