It has been several hours since promethius had left a lasting impression on his power in the memories of the canterlot citizens just to leave straight after, straight towards chrissillis's hive. The whole of canterlot is in shock with gaurds on full alert, watching the mass of machine that is promethius move away at incredible spead. The only reason hes still in sight is because his size and the smoke billowing out his chimney.
"Sister, I worry that he will do something to drasticly change the future of every race in equestria." Luna says in an almost whisper.
"I, I am unsure, luna. I honestly am scared by the fact such a creation still exists..." celestia says.
If it wasnt for the fact that they are inside celestias private quarters then anypony outside would have started panicking or questioning why she said 'still exist'.
"I aswell dearest sister. We destroyed all the recorded war machines that were created. But that just means that he had not been recordd at all..."luna says.
both princesses are suddenly startled when a loud knocking echoed through from the door.
"May I enter Princess celestia, princess luna?"came the familiar voice of princess twilight.
the door (suddenly encased in a golden glow) creaked open and twilight entered with a aincent scroll in her own magical grasp.
"I found this in the archives. It lists every single war machine ever created, except it doesnt mention anything about our destructive friend. However it looks as though the last page had been ripped from it early in its public release." Twilight says with a woried expression covering her normaly joyfull expression.
"Dearest sister, you dont suppose that page held information on, him, do you?" Luna says with a deep frown.
"If so then we had better find this missing page before it falls into the wrong hooves." Twilight says with what can only be described as a look of worried determination.
The hallway outside the room is suddenly filled with the sound of armoured hooves galloping towards them. Suddenly the royal gaurd are rushing into the room with an alicorn who looks almost as old as equestria itself.
"Your Highness's, we found this, citizen, at the remains of soft rock mine. He was muttering something about how it wasnt as much damage as he expected from his, son." One of the gaurds suddenly explain while bowing down infront of the royalty.
"I wasnt mumbling, you fool. My son could hear me, even though he was on the side of that mountain with the princesses bothering him! My apologies princesses. My name is, um, well I seam to have forgotten over the many years that have passed since I forced promethius into his cell." The alicorn says doing a slight bow.
"I take it youre the one who tore the page about him out of the book then." Celestia says staring curiously at the strange alicorn.
the strange alicorn simply nods and holds up a sheet of paper in his blood red magic.
"The information on this paper could put the whole of equestria at danger. It holds the information needed to allow him access to his memories, memorys wjich will cause him un fathomable amounts of hate and rage." He explains shortly.
elsewhere
"If you wish to live you will move out my way! I wish to speak with your queen!" The metalic voice of promeathius echoes through the thousands of changelings between him and their hive.
"Say what you will from there, beast!" The voice of chrissillis calls out from behind the swarm.
"So there is a new queen. Maybe we can solve the dilema I had with the previous queen then. I am promethius, I would ask your name but I doubt id resieve an answer. I know how secretive changeling queens can be."
As soon as she hears this, chrissillis gives the order for the drones to seperate a large enough gap to be seen by promethius.
"Ah! So were open for negotiation are we? Good!" Promethius says with a hint of happiness in his voice.
"So youre the monstrosity who sent fear straight into the heart of canterlot. I senced such a drastic change from here.i could of used somepony like you when I attacked canterlot not too long ago." She says with a hint of admiration to her tone.
at hearing this promethius lowers himself to be face to face with the changeling queen.
"The last changeling queen I saw I killed because she attempted to kill my *fssssstttvvvvvspttt*" the last part of that sentence was cut out with the sound of sparks and sizling metal.
At this she raises an eyebrow and smirks. " I dont believe you realy remember youre past that well. Do you, promethius?" Chrissillis says now grinning. "You will do as I say and I will return your memory to you. Dont and I will destroy whats left of it." She growls the last part.
Giving off a very noisy sigh and burst of steam promethius says "what is it you ask of me?"
chrissillis now grinning says "we will take canterlot for the glory of the hive!" She yells and leaps onto the balcony on promethius's head.

back in canterlot...
"What do you mean your son was the heir to the throne!" Celestia yelled in her equestrian voice.
Braking the arguement allmost instantly a pannicked guard rushes in and yells "its comming back! With an army of changelings! What do we do!?"
suddenly the whole room goes silent. Not even the sound of breathing can be heard.
"I will go and try to convince him to stop this madness!" Celestia says but is stopped by the newly found alicorn.
" no. Hes my son. I should stop him. Its my fault he's what ne is anyway." He says but before he can leave the whole of canter lot shakes as a single word is sent reverberating arou d its halls.
"FARTHER!" Promethius's voice laced with pure hatred sends fear into every living creature for miles.
sighing the alicorn in question walks up to one of the windows I the wall and sees womething thought he never would. Queen chrissillis and an army of thousands of changelings marching/flying staight for them.
"And here I was hoping they wouldnt make an allience"
as soon as he says this he immediatly regrets it. He suddenly recieves angered glares from everypony in the room.
"I guess I should explain..."

Promethius's point of view.
"That coward better come face me himslef. I will tear the world apart to extract my revenge from that traitor to the crown and family!" He says in a clearly hatefull tone.
"I knew he was a traitor to his family, but to the crown aswel? Is that why youre so mad at him?" Chrissillis says with fear etched into her voice.
"That monster killed my grand father! King elemental stike! I was the heir to the throne before he framed me for the murder whilest I was at war!" Promethius yells as his body shakes and a large satellite raises out of his back and is launched into orbit around the planet.
"W, what was that?!" The changeling queen asks while watching it fly out of sight with a thick trail of smoke behind it.
"A little suprise gift for my father. I hope he accepts it with open hooves. Either way, he wont escape its power!" He says following it up with loud, almost insane laughter.
suddenly the whole royal guard assembles outside canterlot in an attempt to defend it.
"Realy father!? Convincing the princesses and their guard that youre worth defending after you killed the king in cold blooded murder! Just to frame it on youre own son and true heir to the throne! He was the kindest pony I have ever met and I believe even sister doubted those lies you told everypony! She knew I was in the middle of the battle feild at the time! And yet you still betrayed family and crown!" Promethius shouted so loud that the guard had to cover their ears aswell as causing all the changelings and their queen to fall to the floor.
this caused a huge spark of fury to form inside the aincent alicorns mind. "How dare you reveale the past to them! This was my last shot at taking the power thats rightfully mine! The power I was willing to share with you!" The alicorn yells after telleporting himself infront of his son.
"Now away with you! Go back to the depths of the planet where you belong!"
A large flash as bright as the sun blinds everypony temporarily as promethius is sent into a pit that goes straight to the core of the planet.

3 months later

fires spread throughout canterlot as the trio of princess's battle the evil alicorn who uses both normal and dark magic to repel and deliver powerfull attacks.
no pony notices the huge amount of smoke erupting from a deep, seemingly endless whole where soft rock mine once was. That is until the evil alicorn stops all his attacks to glare at it.
seeing their chance the princesses hit him with enough energy to send him hurtling through canterlot mountain and into the distance.
"Sister, why did he stop?" luna asks with a worried frown.
"Because our long lost friend has returned." Celestia says pointing out the pillar of smoke with her hoof.
with a quick glow of her horn celestia is standing by the top of the pit. She simply waits until the ground starts to shudder with every step promethius makes towards the surface.
after 3 hours of the shudders getting more and more powerfull a great metal limb rises over the edge of the pit, shortly followed by another. She is suddenly greated by the towering body of promethius striding over and past her, towards canterlot.
"And why are you going promethius?" Celestia asks in a harsh tome.
"I have no patience for you, so called princess." Promethius says causing celestia to flich from the hate that still stains his voice.
before she can respond a large red explosion send luna flying from the royal chambers.
"Maybe I under estimated him. I should reveal both suprises he seams to have forgotten the true heir to the throne has." He mutters to himself.
Before celestia can even start asking a question about what he just said promethius starts to give off a very dark blue glow and yells as loud as he can.
"GUARDIANS OF THE ROYAL BLOOD! RISE FROM YOURE GRAVES AND FULFIL YOUR DEBT TO THE CROWN! I ASK YOU NO AVENGE THE KING AND PROTECT THE ROYAL SUBJECTS!"
the grounds all around equestia rumble as giant stone and metal hooves lift giant mechanical ponies with huge axes, swords and spears. All of them have glowing blue eyes and march towards promethius's father, who has now lost all colour to his face at the sight of the aincent golens who only answer the kings call.
however. Instead of giving up on the spot he desides to teleport ont promethius and rip a large sheet of metal from his back.
"And there I was thinking youd never do that. " he says then turns to the soldiers. "Kings ponys! I hereby have decided whom my heir to the throne will be and who you will for ever serve unless they say otherwise. Princess luna, princess celeastia and princess twilight.I bid you all good bye!" As soon as he says this celestia and the unknown alicorn gasp loud enough to make promethius turn around.
Looking up into his father's hate filled eyes he says one last sentence."archimedes test fireing in 3, 2, 1." A huge, blinding beam if light shoots down and strikes promethius and his father causing him to implode.
after the dust cloud clears all thats left is a huge pile of ruble and a skeleton that used to belong to the only other alicorn left to knoledge, other than the princesses of course.
The larger pile of rubble suddenly moves and is knocked onto its side. The sound of electronic motors and groaning an be heard from behind it.
"I cant believe that actualy worked." A chearfull male voice that celestia places instantly.
"Promethius? How did you survive something like that? The energy given off by that, what ever it was, was powerful enough to kill thousands of ursa majors! "
All movement from behind the rubble stops. As if frightened of being seen.
"Please, I dont think youd want to see your uncle like this. Just, just go and forget I even exist." The saddened, less mechanical voice of promethius says.
"Uncle? But, wait. Your sister was my, mother?!" Celestia says on the border of tears.
"Yes. And im proud that you managed to make her proud from beyond the grave. I still regret the day I saw her in trauma after my father claimed I killed the king. The look on fer face will haunt me for all time, even as the, monstrocity I am. Im not even a proper pony anymore." He says. Greif clearly forcing him to remain silent.
The rubble glows with celestias magic and is lifted away to find a pkny with most of its body made up of machinery. Half his head is missing and replaced by a small supper computer.
celestia gasps when she sees the horn thats been severed from his head and the huge wings that are supported by a metal frame with small turbine engines attached to the wings themselves instead of the frame that supports them. He has a white coat with a grey and amber mane and tail. Almost all his body is being supported by a strong metal frame and many small pistons.
"You dont desrve an uncle like me. Im sorry but I must go. Im sure you probably dont want a disgrace such as me around equestria any longer than you have to..."
"Wait! You dont have to go. Please, just listen and maybe wait for my sister to arrive. She could help. We can help you to get along with everypony and you can stay in canterlot with us. But"
celestia never got to finnish because luna hits him with a very powerful blast and the satellite enters the atmosphere, aiming directly for promethius. As its falling it fires in the same direction, leavind nothing remaining of their uncle.
just before the blast hits him though one thought shoots through his mind.
"PREPAIRE FOR UNFORSEEN CONSEQUENCES" he says this outloud as he is utterly destroyed by the satellite that he called down on himself.
the only thing left to show what happened is a grave saying 'here lies the last true king of equestria, king promethius. Died to stop the past repeating itself to destroy equestria.'
Everything else was cleared away and the metal remains where melted down and sold to other countries so they could repair the damage caused by the battle for power.
However unaware to everypony their uncles mind was copied to another satellite which is constantly watching over his neices and their empire. And occaisonaly he will fire his weapon on an unsuspecting enemie who plans to attack those he cares for.
he is now known only as equestria guardian angel. The only ponies who knows that it is him who is doing it and not a spell is princess celestia and luna. His last remaining family.
