Reality Log 8752'. "Reality Log, 8-7-5-2-dash."-"In this temporally normalized future we arrived in, we ended up bringing Prime Town, the altered version of the past island we resided in days ago, and the Centipex, all adjacent to this MEGA-adorned island that just recently has chunks sunk into a big jungle biome. Our initial alliance dropped across the land masses, and caught wind of the Anti-Life girl, who turned out to be a part of the Order of the Pariah. We met the syndicates, whose recent unity has been experienced to have driven a saboteur away. And of course, a few happened to stumbled upon Dr. Slone - yes, she survived in her tank - and our SHIFTers, who's been missing ever since after the Zerobreaker war. They're all back, and they got involved in our preparations. And of course, not to mention some of those escaped... wait, aren't the SHIFTers in one of those cells? And wait... there is more landmasses and things stick into this place?"
In a terrain cluster mainly shoved with Prime Town, the land of Centipex, and the two Zero islands in one place. The alliance expanded, accepted the syndicates, and camped in two place, between Slappy Shores from original and now-vandalized Cuddle Cross Track and also in the jungle biome itself.
Noah and Mio...
"Help us! Help!" Noah and Mio stuck in an ice land.
"Wait... Noah, look!" Mio showed Noah.
Several beings, one rather familiar, one vaguely familiar, and other strange creatures. All of them entering a portal made of void.
"Could that be... Our child! Entering the portal from..." Noah realized. "A Herrscher of Void!"
The two then ran towards the being, only to glitched out like a super-collider sign of otherworldly travelling glitch. Both drop downs , and misses the portal. *the portal closes*
"NOOOOOOOOOO!" Born screamed in terror.
Suddenly... Noah and Mio both woke up at the same time.
"Oh, you woke up so snuffing early?" Eunie noticed. "I thought you need some more sleep. C'mon!"
"Whew, it's just a dream..." Mio panted.
"I hope you don't bedwet yourself, Mimi." Sena approached. "It may be good-looking afterwards, but that would still be gross."
"Yeah, we gotta gather around." Lanz stocked. "The whole land's absolutely unique. And then, there's the mission..."
Taking off from Shady Stilts, the Ouroboros walked down to Creeky Compound, and finally crossed into the Rumble Ruins, where much has gathered.
"This isn't the first time we casted the sixth rings. This one is more powerful. All thanks to the hopes of our Earth." Some mascots are talking to a man with with samurai ponytail.
"Huh?" Noah heard it. "Who? Wait..."
"Isn't it... our child?!" Mio is shocked. "Ghondor?!"
"This is Reality Zero," Ghondor introduced to the Olympic and Paralympic and World Cup mascots. "The median point of the omniverse. And this island is governed by the Zero Point."
"This is very interesting, absolutely." Miraitowa (Tokyo 2020) replied. "And I wonder what IPs would we spot... wait, there's your parents over there!"
"Hello, Mr. Noah and Miss Mio!" Someity (Tokyo 2020 Para.)
"Mum? Dad?" Ghondor noticed.
"It's you... my child... our child...!" Noah is moved with.
Noah and Mio simultaneously hugged Ghondor. "You're back!"
"Finally, a reunion with you both...!" Ghondor feels very heartwarming.
"After a literal sacrifice and then revival followed by a fight against the fake two, a reborn boy reunited with his real parents!" Zabivaka (Russia 2018) commented. "Isn't that heartwarming? Not to mention-"
"We've already been spoiled of Xenoblade Chronicles 3 and Future Redeemed so talking about it is getting kinda redundant now." Tom (Rio 2016 Para.) cringed. "But it's very good for him to reunite."
"You're grown up to our physical age now." Mio still cares for Ghondor as ever used to be.
"The last time I saw Dad... become a thing the City fought against, but how did you..." Ghondor brought it up.
"Long story short, I and your Mum actually absorbed our Moebius selves to move forward as among Ouroboros." Noah explained. "That contributed to the end of Moebius, and accomplishing what we and you all desired."
"And we are their friends. We're Ouroboros." Eunie revealed. "From a future distant."
"How long?" Ghondor questioned.
"We remember talking to the Founders all as ghosts, before we six returned." Taion noted. "At least a thousand years, after an anomaly in Aionios."
"A thousand years? A millennia?" Ghondor replied.
"After the death of two's grandfather. You appear to be... 'Ghondor'." Taion continued. "N killed Ghondor in front of the two siblings."
"Matthew? Na'el?" Ghondor realized. "You... Isn't that?"
"Oh crap, now we're gotta spoil it to you." Miraitowa facepalmed. "Moebius Z recruited Noah to become N not only to revive Mio into M."
"Dad... you became Moebius just to bring Mum back?" Ghondor is surprised.
"And she didn't like having to drain life for the Moebius." Noah about M. "She even decided to swap bodies with Mio to take her place in the Homecoming."
"...but also to match Ontos, that chose Na'el as the emotional avatar."/"...しかし、ウーシアに合わせて、感情のアバターとしてナエルを選択しました" Miraitowa revealed. "N was commissioned to kill Na'el and put an end to Alpha, the Ontos that lost ít human-like conscience that manifested as a woman simply called A."
"So N... killing Alpha... wait, what's Alpha?" Noah is confused.
"Already told you, Ontos were split into Alpha the heartless machine and A the conscient avatar."/"すでに述べたように、ウーシアは非情な機械であるアルファと良心的な化身であるエイに分かれています" Miraitowa replied. "N tried to kill Na'el to prevent Alpha, allowing Moebius to snuff out that machine for trying to destroy Aionios."
A flashback of N fighting against Alpha in front of the City folks, and then only to be noticed and then interrupted by old Ghondor, as following... *flashback*
"What's that... strange pillar of light...?" Then Ghondor rushed to the City.
The initial City was being ravaged. The City folks is being led by Na'el Doyle possessed by Alpha who wants to destroy Aionios and move the Citizen over to a new world. And when Ghondor finally arrived at the scene...
"Come. Enter the circle, quickly." Na'el tried to persuade Ghondor. "It's just you and Matthew now."
"Na'el...?" Ghondor is confused. "What're you...?"
N arrived at the scene with some Moebius-led creatures that's also ravaging the City.
"You-... Are you..." Ghondor is shocked. "Father...?"
Meanwhile, Matthew Vandham is rushing to the scene.
"...Why are you doing this?" Ghondor questioned N. "But you told me yourself... You told me to make friends... Say something!"
"He doesn't want us here." Na'el is quick to respond. "We're a nuisance."
"Nuisance...?" Ghondor is even more shocked.
"Right?" Na'el is talking to N. "You who've become Moebius. N... isn't that your name?"
"You... Who are you?" Ghondor questioned Alpha. "What've you done to Na'el?"
"Its name is Alpha." N revealed. "An entity that wishes to erase this world."
"Huh?" Ghondor is confused.
"He's wrong." Na'el denied. "I want to embark on a journey, to the future. There's just a matter of unwanted baggage."
"What're you talking about?" Ghondor questioned.
"Lives." N replied. "We Moebius, and...every last soldier on the face of this world."
"I... What are...?" Ghondor is overwhelmed with emotions and shock. "...and that's why, all this...?"
"See?" Na'el (by Alpha) dismissed. "We don't need them."
"I will..." N decided. "I will arrest it." *closes mask* "This moment... This instant!" *stances*
Cue N and Alpha in Na'el fighting in front of Ghondor.
"You're just Moebius..."-"But... what's this power...?!" By that point, N began to overpower Alpha in Na'el.
"You would never understand." N continously attacked. "This is... my choice!"
"So you choose to stay in the now?" Na'el as Alpha trade blows with N. "To abandon the future?!"
"The one leaving things behind... is you!" Then N dodged and knocked Na'el out.
"Granddad, help..." Na'el pleaded as she struggles to get up. "Please help..."
"Na'el..." Ghondor seeing his granddaughter struggle.
"It is done, Alpha." N went for iaijutsu with his Sword of the End.
"Leave her!" Ghondor intercepted.
The killing blow meant for Na'el and Alpha ended up accidentally went for Ghondor instead. Cue a surprised N realizing.
"Na'el is... She's your family..." Ghondor as he bleeds and Na'el gets up. "I can't let you do this... What about Mum... Did she... want this too?"
"...You don't need to know." N started gaining guilt over dealing that killing blow to his son. "The burden is... mine alone to bear."
"Mum would... tell you... to let it go, I'm sure..." Ghondor replied. "I know it... But you... you can't choose... this path..."
"Ghondor..."
And then Matthew arrived. "Na'el! Granddad!" *gasps*
"This is the path... I have chosen." Ghondor gets it. "Matthew..."
"Granddad...!" Matthew reached for his grandfather.
"Take care of... Na'el..." Ghondor activated his Ouroboros powers and initiated his self-Annihilation Event. "...the future..."
"Granddad!" Matthew cried.
"It's in your hands, Matthew!" Ghondor exploded, and then rushed, giving Matthew and Na'el the Ouroboros powers, as well as splitting Ontos.
And then, with the initial City destroyed, N just stood there, grieving. M teleported to this aftermath and clearly realized that Moebius life isn't going to be happy for either of the two.
-*flashback ends*
"Father... accidentally killed me over Alpha..." Ghondor sighed. "At least Mum realized the truth, and I entrusted Matthew..."
"Thank for letting me and Mio realize..." Noah comforted Ghondor.
"And it appears that N casting away his griefs and regrets and M sending off her conscience ended up bringing Noah and Mio back to the cycle." Taion noted.
"So Matthew and Na'el are our family..." Mio responded. "Where are they?"
"Enough of the City story, I met the mascots after Kiana sent me to a terrain-crazy dimension." Ghondor changed the topics. "I reluctantly volunteered to sacrifice myself for them, to revived their friends and back into fighting. A dragon did it."
"It's an alternative timeline Chya impersonating our former enemy, Flamuna, that sent the dragon over." Vinicius (Rio 2016) explained. "15 days ago, we sensed Chya coming, and nearly a week later, we were forced to fight her and her minions."
"And I had the engineers of my realm create a portal device to send the mascots to dimensions to catch up with and fight that xeno and obstacles from her." Ato (Korea/Japan 2002) replied.
"We used the sixth ring to fix the Earth, and then formed it again when all how seemed lost because Chya stole the powers of the first five rings." Wenlock (London 2012) showed the six rings. "Auroral rings, they're powered by inspiration and olympism."
So the mascots explained what happened using the downloaded recaps of the broadcasts from the Earth they went from.
"Blue ring represents Europe and water." Beibei (Beijing 2008) explained.
"Black ring represents Africa, forest and wood, basically plants." Jingjing (Beijing 2008) explained.
"Red ring represents America and fire." Huanhuan (Beijing 2008) explained.
"Yellow ring represents Asia and earth." Yingying (Beijing 2008) explained.
"Green ring represents Oceania, sky and metal." Nini (Beijing 2008) explained.
"And the white ring represents the world, reality and hope." Fu Niu Lele (Beijing 2008 Para.) explained.
"Yes, it's true." Mandeville (London 2012 Para.) confirmed. "These are the rings."
"And we used them to kill that Chya." Ghondor revealed. "Unlike the kind whistleblower of QDOT, the truly Forgotten Four her were driven crazy, impersonated the mascots' enemy-turned-friend with fire powers, and tried to destroy their Earth. She nearly succeeded."
"Oh, hello... wait, this kid's all grown up?" Lanz noticed a grown-up SCP-239.
"Sigurrós Stefánsdóttir." Kiana Kaslana (K-423) responded.
The response from the Herrscher of Finality suddenly struck the modern Ouroboros.
"Kiana too? Wait... weren't you fixed with the real... what?" Lanz is confused.
"Sorry. Turns out that the one who made appearance in P-1 Grand Prix Cross Edition is converged, just like Chya." Kiana confessed. "The real Kiana is currently busy. I'm the clone K-423, who's now basically a goddess, dedicated to protect all that's beautiful-"
"What!?" The modern Ouroboros are shocked.
"Hello, everyone." Spider-Man 2099 (from Earth-928) appeared. "I'm Miguel O-Hara, the Spider-Man 2099, and I protect my multiverse through canon events."
"I watched Across the Spider-verse last night, so I already know. Canon Events are basically what's to happen to a timeline." Eunie briefly gets meta. "Patching anomalies, even at the cost of innocent's lives throughout your multiverse? Damn!"
"I don't always like what I have to do. But I know I have to be the one to do it." Spider-Man 2099 told Eunie. "I've given up too much to stop now."
"So you're from 928B, not the normal 928-" Eunie took that-
"Mr. O'Hara, this is Reality Zero." Ghondor introduced to Spider-Man 2099.
"I know it from Earth-616 Spider-boy's experience of this kind of reality." Spider-Man 2099 responded.
"You never knew Reality-616 is basically Earth-616." Taion noted. "The Continuum Exploitation Authority told us about Reality Zero. And then some."
A woman with Akatsuki cloak and blonde hair walked by. It's Ms. Continuum herself.
"Oh, isn't it Ms. Continuum of CXA." Noah noticed. "Ghondor, greet her friendly."
-*yawns* "People's gathering, so I've got to get up and get here. Hello..." Ms. Continuum greeted.
To be continued...
