And now, once more, I come at you with another idea!
A crossover in fact!
One with a world divided by light and dark, but muddied by the greys between.
A world divided between a Gardener and a Winnower.
A world divided by a Traveller and its Witness.
A Hero's Destiny
(Inspired by Destiny)
In the distant past, something happened.
No one knows what it was. No one knows why either. So much of humanity's history after the Quirk Awakening a thousand years ago had been lost to them, gone and forgotten. All that is known is that something happened, something triggered the quirk awakening...
And before that, the three races that make up humanity, Human, Exo, and Awoken, were protected from malevolent forces of darkness by mythological, undying heroes of legend.
The Guardians and their Ghosts.
Now is the modern day, and the age of All Might reigns across the world, ushering in a new age of peace and prosperity to the planet of Earth.
But there has been an awakening, deep down in the earth and across the solar system.
The forces of light and dark are beginning to move into play once more.
And it all begins with Izuku Midoriya, a quirkless boy in the midst of being bullied by his former childhood friend, Bakugo Katsuki.
Their day in Aldera High School is the same as any other, and events soon begin to follow as canon would, all the way up until the moment that All Might tells Izuku that he cannot be a hero and leaves with the Sludge Villain, leaving Izuku to himself.
This time, when All Might loses the Sludge Villain, it does not attack Bakugo, and Aldera is not attacked.
Not by the Sludge Villain, at least.
Because the Sludge Villain is killed in an alleyway by a monster with four arms.
The next day, everything is going as usual for Izuku, with Bakugo and his cronies still tormenting him, and his dreams now shattered and broken thanks to All Might's words.
But then, he looks out the window, and sees a lumbering brute of a creature breaching the school gates.
A four-armed beast covered in boils and rotting flesh, covered in old metal and drapes and holding a massive cannon.
It is Ra'tixx, the Awakened. It is a Chieftain. It is an undead Eliksni.
It is a Scorn.
And it opens fire.
Izuku Midoriya is caught in the first blast.
Izuku Midoriya is killed.
And the school is thrown into chaos as the Chieftain summons its hordes of Lurkers and Ravagers and Raiders and Screebs and Stalkers and Wraiths and Abominations, and the Scorn swarm the area like a horde of locusts.
The heroes are quick to respond, and they are able to drive Ra'tixx and its fellow Scorn into a retreat, but Aldera is left in ruins, and almost everyone inside has been slaughtered, with the sole exception of Bakugo, who was barely able to defend himself from the Scorn before All Might jumped in to save him.
But in the aftermath, a little light bursts out from the darkness. A small machine-like device floating through the air.
It calls itself Mikumo.
It is a Ghost.
And it raises Izuku from the dead, as the world's first Lightbearer in a thousand years, with no memory of his previous life, and no understanding of what is going on around him.
Mikumo leads Izuku underground and out of the eyes of the heroes, and reveals that he is just as confused as Izuku. He has only just been brought into the world as well. All the two of them know is that Izuku has no memory of who he once was, he is a Titan, he can wield the Light, he cannot permanently die, and Mikumo is the key to that resurrective immortality.
But as they stay underground for the next ten months, Izuku - now calling himself Deku, as it is one of the few memories of himself that he can barely recall - begins to hear reports across the news of the Scorn, led by Ra'tixx and its Chieftains, attacking random locations across the city, abducting dozens of heroes and innocents with each attack and killing dozens more, he feels the itching, desperate need to intervene.
And so intervene they do.
Tracking down the various hideouts of the Scorn, Deku and Mikumo discover that the undead Fallen have been performing gruesome rituals on their captives, experimenting on them with dissections and attempting to harvest their quirks, filling them up with Dark Ether to turn them into Ether farms, and sacrificing them for their dark gods. Resolving to stop them, Deku finds their lair underneath the ruins of Aldera and confronts them, freeing the captives and confronting the Scorn, taking them down one by one with his new Super ability, Ward of Dawn, and then coming face to face with the head Chieftain behind the operation, Ra'tixx the Awakened.
(This would be the Destiny equivalent of a Strike, essentially.)
It is a long and gruelling duel, but eventually, Deku is able to defeat it, giving the monstrous Scorn its second demise and ending its demented rituals.
However, all of this is interrupted by All Might, who finds him in the old ruins after receiving reports of a fresh wave of Scorn and violence erupting from the destroyed school. Upon seeing the boy that had been killed, the boy that he had let down and let die, up and about once more, and upon hearing the thankful words of the people that he has saved, All Might finds himself unable to arrest the boy.
Instead, he takes him to Nezu.
Upon seeing the Lightbearer, Nezu tells Deku that he has only ever heard of them in legend, and is himself unsure of how he can help the Risen in mastering his new powers, but he will certainly try.
And he can start by enrolling him into U.A.'s Hero course.
Deku and All Might are surprised by this, but are also grateful, and thank him for the opportunity.
And when they leave, Nezu contacts someone on his personal communicator, and tells them to inform Caiatl that a Guardian has been risen.
As the new year begins, Deku and Mikumo begin to acquaint themselves with their new classmates and peers, and we begin to see several changes in them thanks to the fusion of these two universes. For instance, Ashido is an Awoken instead of just a mutant, and Ibara, Aoyama, Shinso, Koji, Momo, Monoma, Yui, Reiko, and two of the teachers Midnight and Eraserhead are all Awoken as well. However, since Exos cannot reproduce, none of the children are Exos, though in this reality some of the teachers and heroes are Exos, like Gran Torino, who is Torino-43 in this world, whilst the likes of Power Loader and Thirteen are Maijima-13 and Kurose-11 respectively.
Whilst he is at U.A., Deku and Mikumo begin to make friends with some of the people around him, such as Jiro, Iida, and Ochako in his class, Yui and Tetsutetsu in Class 1-B, and also Shinso from General Education and Hatsume in Support, who begins to help him with developing his tech and equipment-
(In this universe, Hatsume is fascinated by the old stories of the Guardians and their Ghosts, and has begun to develop an obsession with unlocking the secrets of a fabled species known as the Vex, and the old legends of the Black Garden...)
-However, he begins to grow a dislike to one Bakugo Katsuki, who apparently knew him in a past life and is really annoyingly rude about it.
Meanwhile, Deku and Mikumo soon become famous for their exploits across Musufatu and their takedowns of the Scorn, as well as being the first fabled Lightbearer and Ghost pair in a thousand years. Because of this, and because of their rapidly growing skills with their powers, Deku soon starts to grow a sense of arrogance in his skills, believing himself to be much better in terms of skills and power compared to his peers.
This will come to bite him later, as when the USJ comes to pass and all of Class 1-A are gathered outside the entrance to the building, when Shigaraki, Kurogiri, and the rest of the League of Villains step out to face them, the two villains don't bring street thugs and brutes.
They bring Cabal.
A remnant of the Red Legion from a thousand years before, hired on by the League as mercenaries and led by the self-proclaimed Valus Ca'lall, an Incendior with high aspirations and low options, believing his unit and himself to be destined for greatness, and in killing All Might they would accomplish that.
At first, Deku would move to take down as many of the Cabal mercenaries as he could, but would soon find himself overwhelmed by the sheer amount of fire that they were throwing out at him as they were scattered across the USJ.
But then, tragedy would strike, as a group of students, under Deku's protection, would be cornered by a group of Cabal, led by Valus Ca'lall, and Deku would declare that the students were under his protection.
It was then that Deku notices the necklace of dead Ghosts around Ca'lall's neck, and the brutish Incendior decides to challenge that...
By grabbing Jiro, throwing her to the ground, and stomping on her head, flattening it into a red paste and killing her.
Ca'lall has just murdered Jiro, and Deku could do nothing about it.
The Lightbearer is enraged by this and goes in for the attack, but is beaten down by the self-promoted Valus' forces, shield-based by his Phalanxes, pummelled by his Legionaries, slashed at by his Gladiators and blasted by his Psions' Void abilities. He is killed and revived by Mikumo over a dozen times, and by the end of it he is left bloody and beaten, now hiding behind his Ward of Dawn from the Cabal with the other students that had sheltered away with him.
But then, soon enough, All Might arrives in the USJ to defeat the villains, and he and Ca'lall go head to head with each other, the two of them duking it out before Skigaraki's Nomu joins in on the pummelling, its body covered in runes and symbols that seemed to have a glowing yellow resonance to them as it joined Ca'lall in beating down All Might, and even when the other heroes arrive, the fight between them and the League's Cabal and Nomu is still one-sided in the Cabal's favour.
But then, just as all hope seems to be lost, a new light is risen in the chaos.
A Ghost by the name of Jackie enters the USJ, and revives Jiro, turning her into the second Lightbearer to see the world, once more with no memory of the life she once led beforehand...
But when she see the chaos around her, she knows immediately what to do, and gets to work.
Picking up a discarded Projection Rifle from a dead Centurion, Jiro the Hunter summons her new Super, Blade Barrage, and takes down several of the Cabal before moving to challenge the Nomu. Ca'lall, realising that the odds have now turned against him, retreats himself and the rest of his forces via transmat, and Shigaraki and Kurogiri are forced to retreat as well, but not before sending the Nomu after Jiro and telling it to kill her.
It is a long and drawn-out fight, but eventually, after many deaths and revives, Jiro is able to bring down the Nomu and kill it, finishing the fight and defeating the villains, leaving only the corpses of fallen Cabal and a dead Nomu in her wake.
In the aftermath of the battle, U.A. is placed into lockdown and the corpses of the Nomu and Cabal are dragged away by the authorities. Meanwhile, Jiro is questioned by the police but is left confused by their questions, as she doesn't remember anything before being risen by Jackie, not even how she died. The only reason she knows that her name is Kyoka Jiro is because they were telling her it was.
Later, Deku approaches Jiro and tries to apologise for letting her die, but Jiro waves it off. She doesn't remember it happening, so no harm no foul.
The other members of their class do not feel the same way.
However, there is little time for them to dawdle, as Musutafu is placed under lockdown. In the aftermath of the failed assassination attempt at the USJ, Ca'lall has shifted his tactics and decided to lay siege to the city. Soon enough, his forces begin their invasion of the city, throwing a Cabal Carrier up into the air and launching their assault from the flying platform, sending multiple drop pods and Threshers down to shuttle their troops down to the surface and lock down the city.
However, not all of Ra'tixx's Scorn were killed by Deku, and now they are coming out of the woodworks to begin their own takeover of the city as well. Now Musutafu has been locked in a turf war between the Cabal and the Scorn, and has to be entirely evacuated before the heroes can begin their own operations on them.
Essentually, Musutafu has been turned into a patrol zone.
U.A. is turned into a fortress for the evacuees, and in the middle of the chaos, Deku and Jiro are called up by Nezu to the main office, where he introduces them to two people that may know how to train them to wield the Light.
Empress Caiatl, Princess-Imperial of the Imperial Cabal, Mithrax, Kell of the House of Light, and Queen Mara of the Awoken.
They transmat out of U.A. and are taken to Neptune, to the alien city of Neomuna, and begin their training with the Corsairs and the Cloudstriders.
Meanwhile, back on Earth, the students of U.A. and their families remain locked in the bowels of the school, and Hatsume, feeling guilty for what happened during the USJ and for not being able to properly help Deku with her gear, becomes more and more absorbed in her research into the Vex and the Black Garden, spending day and night looking into them as a way to distract herself from the crushing guilt...
Until one night, she wakes up to be greeted by the mechanical frame of a Goblin, covered in moss and overgrowth.
It is a Vex of the Sol Divisive, and it invites her into the Black Garden.
Elsewhere, many students of 1-A, traumatised by what they have seen at the USJ and embittered at Jiro's death at the indirect hands of Deku, begin to suffer from whispers and visions of pyramids, one on the moon, and one on the icy world of Europa...
And Bakugo, resentful of Deku's accomplishments and how he had got into U.A., as well as traumatised by the events of the USJ himself, would be approached by a trio of figures in chitinous armour, promising him the powers necessary to make him a hero if he would stand with them. He would reject them violently, but the words of the emissaries from the Lucent Hive would continue to linger in his mind.
With Deku and Jiro, the Titan and Hunter duo begin to hone their skills with the Light on practice foes and old Frames salvaged a thousand years ago. Whilst they are there, Deku is given a severe dressing-down by Caiatl, who chastises him for his arrogance, as that is what got Jiro killed in the first place. Suffice to say, Deku is humbled by the experience.
Elsewhere, Hatsume continues to be absorbed into the inner workings of the Sol Divisive, and would begin to explore the Black Garden, coming across the old ruins of the place where the Black Heart once was, before coming across the statue of the veiled woman in the depths of the garden.
In a trance, she would place her hand on the statue, and would be overcome by visions of a world all of her own, of one built of the strength of her creations and inventions, of one where Vex of the Sol Divisive bowed to her as she made herself into their new Black Heart, into their new Queen of Final Shapes...
Hatsume would return to Earth as a changed woman. In her hands she would hold a Splinter of Darkness, and she would use it to slit the throats of her parents and siblings in their sleep, destroy their bodies, and begin construction of not only a lab dedicated to the study of the Vex, the Sol Divisive, and the creation of a gateway made out of their technology, but also the study of the Darkness objects and how to replicate them, spreading them out to various other students and heroes in the school.
With these new deaths to her name, the construction of her throne world would begin.
After a while, Deku and Jiro return to Earth, alongside Nezu, friendly forces from the Imperial Cabal and Eliksni Splicers from the House of Light, and begin to run operations in a coalition with the heroes in Musutafu, taking down various opposing Cabal and Scorn operations in the city and clearing out multiple lairs and champions belonging to the two sides, demolishing their command structures before eventually moving on to the Cabal Carrier up above (in the Destiny equivalent of a Dungeon) to confront Ca'lall once more alongside a cadre of heroes, Imperial Cabal, and House of Light Splicers.
Eventually, they would succeed in their mission. Ca'lall would be felled by Deku and Jiro, his Red Legion forces ravaged by the heroes, and the remnants of his army of Cabal would surrender, forced into prisons seen over by both heroes and Imperial Cabal, whilst Eliksni Splicers and engineers would disable Ca'lall's Carrier for parts and assist in supressing and driving back the Scorn.
Musutafu would be saved, but it would herald a new age as the Imperial Cabal, House of Light, and Reef would be forced out of hiding and into the open of Earth's geopolitics and hero society in general, reopening the age of Intersolar travel once more, albeit in shaky, unstable legs.
As Musutafu begins to rebuild and the geopolitical landscape of the planet shift around them, the students of U.A. would be joined by Deku and Jiro once more, and they would begin to repeatedly be whisked away by their new Intersolar allies in training their new allies, as well as teaming up with the likes of Eido and Petra to investigate what happened a thousand years ago, as even the likes of Mara Sov does not know what happened.
One second the Traveller and the Witness were about to go head to head, and then the next... nothing. They were gone. As was every other Lightbearer across the system. All that was left were people on Earth, all with new powers to themselves.
However, back on Earth, Momo and several others in her class would begin to receive strange visions of a Pyramid on the moon, and would begin to grow obsessed with discovering what they are and what they mean.
Meanwhile, Hatsume would become a serial killer in her efforts to bring more of the Sol Divisive Vex into the world, construct her throne world, and advance the creation of her technology, eventually creating a splice between U.A.'s tech and Darkness splinters that she called the Resonant Generators. She even goes as far to drown one of her peers, Bibimi Kenranzaki, in a pool of Radiolaria to corrupt and turn her into a Vex Hydra frame known as Hḗphaistos, the Transformative Mind.
Soon enough, in an effort to boost the morale of both their students and all of hero society, U.A. would host the Sports Festival sometime after Musutafu's rebuilding, though there would be much tension in the way of jurisdiction, as both the Imperial Cabal and heroes of U.A. and the HPSC would claim the rights to security for the event, a legal battle that U.A. would win out.
However, at the Sports Festival, Deku and Jiro would come into direct conflict with not just their fellow sort-of peers in both the hero course and the other courses, but also Hatsume, who has now been thoroughly corrupted by the Darkness and the Sol Divisive, and has been handing out her Resonant Generator inventions to dozens of her peers, corrupting them in turn. Now, in the middle of the Sports Festival and during her round with Deku, Hatsume activates the generators across the stadium and summons forth her new Sol Divisive minions to attack the heroes in the arena. The fight between her and Deku is long and arduous, especially since they keep jumping between their current dimension and Hatsume's Throne World in the Ascendant Realm-
A throne world of which is microcosmical when compared to the likes of Eleusinia, the High Coven, or High War. It is more comparable to the Oversoul Throne, Toland's sliver of a Throne World, or even Hirak's Ascendant Plane. However, hers is riddled with plant overgrowth from the Black Garden and Vex constructs spliced with Darkness/Pyramid architecture and Human technology, and is riddled by puddles and pools of Radiolaria.
-But eventually Deku and Jiro are able to defeat the Sol Divisive and repel their attack, and send both Hatsume and her Vex minions, including Hḗphaistos, the Transformative Mind, into a retreat to both the Black Garden and Hatsume's Throne World. However, in the attack, many heroes and civilians have been killed, including Shinso, who was found by a Ghost by the name of Sarudahiko and revived into a Warlock with the Super of Stormtrance.
Then, U.A. and their allies receive reports of Sol Divisive attacks, not just in Japan, but across Earth, Mars, and even Neptune as well, all of them using the Ascendant Realm as a jumping off point to do so.
Now with Hatsume gone and at the head of a massive threat via the Sol Divisive, Shinso is kept behind by Nezu to begin his own training on how to handle his Light abilities, while Deku and Jiro travel to the time-displaced Mars to find answers as to how to get into the Black Garden once more, exploring the derelict Braytech facilities and battling through hordes of time-displaced Grasp of Nokris Hive, Virgo Prohibition Vex, and Red Legion/Blind Legion Cabal, only to find that the gate to the Black Garden has been destroyed a long time ago.
Then, the new Vanguard that is forming around them remember of the old gate that had been used by the Vex to get onto the Moon during the Scarlet Keep debacle, and they head to the moon, only to find that it has been dramatically changed since the last time that anyone stepped foot on it. Since the end of the age of Guardians a thousand years ago, the Leviathan exploded and left hundreds of shards of itself scattered across its desolate landscape, all the while the Scarlet Keep, fuelled by Egregore has grown in size and power according to the power of the Hive of the Hidden Swarm, and the Nightmares of the Lunar Pyramid have grown outward to spread across Lunar as well. Now the moon, from its surface to the Hellmouth and the catacombs below are infested with not just the armies of the Hidden Swarm, directionless and split between a hundred different warlords trying to claim Crota's legacy for themselves, but also the mindless, braindead armies of clones of Cabal Loyalists from the aging cloning vats from the old shards of the Leviathan, and the Nightmares that plague the dreams and lives of those who walk Lunar's surface, led by the phantoms of past regrets.
Deku fights his way through the ruins of the Lunar surface, and finds the gate below the Lunar surface, broken and defunct, but still relatively intact. At the same time, Queen Mara directs Jiro and Mithrax's Eliksni Splicers into the Ascendant Plane to attack the Sol Divisive directly, cutting off their pathways through the Ascendant Plane and into the material realm, forcing the Vex to halt their invasion of the planets in Sol and confront the Coalition directly.
Meanwhile, Deku and the House of Light would get to work on rebuilding the gate to the Black Garden, but the former would find himself hunted and haunted by deadly apparitions. The Lunar Pyramid would pluck the Nightmares of Ca'lall, Ra'tixx, and Hḗphaistos out of his mind and manifest them into the real world. Worse yet, Hatsume has become aware of their plan and, through her new connection to the Darkness and the power that it grants her, manifests herself as a Nightmare and begins to taunt Deku, diverting the Nightmares and Cabal Loyalist clones to kill him and impede their efforts to breach the Black Garden.
And worse problems would begin to arise.
Back on Earth, as the heroes and Imperial Cabal continue to bloody themselves against the Sol Divisive, U.A., with the Risen Shinso at their side, and the HPSC would finally fnd the time to dissect the Nomu's corpse, and would learn that the runes carved into its alien skin had the same resonance as the technology that Hatsume was using. Worse yet, they would learn that All for One had used the body of a Tormentor to make the Nomu.
Meanwhile, Momo and several other students of U.A., either corrupted by Hatsume's Resonant Generators or tempted by the whispers that they have been hearing in their sleep, would sneak onto and hijack two Eliksni ships leaving for the moon.
One of them would travel to Europa, to the icy moon filled with cranking Vex and age-old Braytech ruins and a rusting A.I. and the shambling remains of a Fallen House still clinging to lost dreams of vengeance through their use of Stasis. These children would be met by the Archon Aspirants of their House, but instead of killing them, these Eliksni would instead lead them to the Europan Pyramid, to the Ziggurat, and to the Cruxes of Darkness that would give them the powers of Stasis that they desired so.
Through these Humans, these children, the dreams of House of Salvation would be realised.
The other ship, the one that the likes of Momo and several other students of 1-A that had been touched by Darkness would takeover, would complete its journey to the moon, where they would in turn be met by the trio of Nightmares known as the Drowned, the Forgotten, and the Sunken, all three of them controlled by Hatsume (and through its newest Disciple, an enigmatic Voice in the Darkness), who would lead them around the ravenous hordes of the Hidden Swarm - hungry for sacrifices to their dead gods Crota and Oryx - soaking them in the fields of Egregore all the way and drowning them in their miasma, before finally bringing them to the Lunar Pyramid, and the veiled statue inside.
They would commune with the statue, and would take from it the knowledge on how to use the Darkness.
And around them, the Nightmares, Scorn, and Taken that had gathered in the depths of the Lunar Pyramid would bow to the newest avatars of Darkness in supplication.
Down on Earth, the Sol Divisive's assault on Earth would continue, and other forces in the background would begin to make plays of their own.
Stain would happen upon the stragglers of the Red Legion in Musutafu and impose his will upon them. The Cabal remnant surrenders themselves to him as he becomes an unwitting and unknowing agent of darkness, and become his newest tools in culling the undeserving from hero society.
The Shie Hassaikai would come into contact with an entire Fallen crime syndicate known as the House of Spiders, who would begin to supply them a new variant of Trigger. One mixed with their own Ether.
The leaders of the Meta Liberation Army would be approached by a strange alien figure in chitinous armour. The Acolyte of the Hive would compliment them on their philosophy of survival of the strongest, and would offer them the weapons (of Sorrow) and tools they would need to succeed, so long as they give themselves to the way of the sword. Soon enough, a dozen of the MLA's finest members would begin to eat and ingest the worms that it gives them, and begin to acquire demented power for it, along with the need to tithe blood to their new parasitic embryos.
Bakugo would continue to ponder the words of the emissaries of the Lucent Hive, and would end up working with them to investigate a series of heroes being corrupted into Wrathborn by a strange Cryptolith. As he worked with them, he would slowly become more obsessive with proving himself better than Deku and the other Lightbearers, and would listen to more of the Lucent Hive's words as he began to consider their offer.
The teachers at U.A., in the midst of the Sol Divisive's assault on Earth, would begin to encounter Cabal from the Shadow Legion, and, alongside Shinso, would unearth a desecrated Pyramid underneath Earth's surface, covered with overgrowth made from the Light and housing not just remnants of the Shadow Legion and their Tormentors, but the corpse of a God of Pain inside.
On I-Island, Melissa and the other scientists there would continue their secret study of not just Braytech equipment and technology, but also the remains of the uprooted SIVA manufacturing complex that they have kept hidden away from everyone, they would be unaware of the threat looming on their doorstep, of not just Wolfram and his goons, but also a reborn, and fully robotic Taniks and his army of Exo Fallen.
All the while, as the children of Light and Darkness begin to pick their sides and wage their war against each other, the League of Villains begin to lick their wounds and seek to find an advantage in the chaos, and All for One would introduce their newest member to them.
Fikrul, the Fanatic, Archon Priest and Baron of the Scorn.
And as he gathers his forces, All for One would order more Nomu grown from the corpses of the Tormentors he has gathered, and summon forth not only the Taken, but his corrupted army of Ghosts to his side, twisted plans forming within his Darkness-fused mind.
And as the new Children and Disciples of Darkness returned to Earth, armed with new powers of Stasis and Nightmares, and as many more across the world are either risen as Lightbearers or tempted by Darkness, Deku, Jiro, and Shinso must rise as Titan, Hunter, and Warlock respectively, and become the new Vanguard for a new generation of Guardians.
And as a dozen new threats - Hatsume and the Sol Divisive, Momo and the Nightmares and Cabal Loyalist clones, the Hidden Swarm, the stasis-infused 1-A and House Salvation, Taniks and his Exo Fallen, Stain and the Red Legion, the MLA and the Hive, the Wrathborn heroes, Bakugo and the Lucent Hive, the Shie Hassaikai and the House of Spider, the Shadow Legion and the Tormentors, and the League of Villains and their Scorn, Taken, and corrupted Ghosts - step out to face this brave new world, all of them aligned to the cause of Darkness, whether willingly or not, our heroes and Guardians must ask themselves a simple question:
What happened to the Traveller, to the Witness, and to all the other Lightbearers that came before them?
Eyes up, Guardian.
A new legend is rising.
I don't think there are any fics at all out there where Mei Hatsume has been one of the central villains in a story, but hey, to each their own.
As always, if you want to use this idea, then send me a PM, or just leave a comment. After that, it's all yours.
