It was a night perfect for a camping.

Perfect for a Krogan who would be stalked and probably gutted, eaten or both by nearly all predatory nocturnal fauna in the radioactive landscape of Tuchanka, up and including gigantic acid-splitting Thresher Maws, that is.

And there was an apparently underprepared group of humans sitting near a campfire and toasting marshmallows without a care in the world. Or worlds.

For you see, those are not normal humans, and at least a pair of them could be some of the most deadliest beings present in the planet.

"... Remind me again why we're in the world of the giant earthworms." deadpanned a young woman in ashen blond hair. She had a faint scar under one of her green eyes, more specifically the left cheek, which is partially covered by some bangs of hair. Her clothes seemed to be fine for travelling through the Middle Ages or a fantasy setting. There were two sheathed swords leaned over the rock she was sitting on: one of steel, another of silver.

"And why not? This isn't the only time we came across a nuclear wasteland." another ashen blonde swordswoman replied, but this one had cerulean eyes and Asian factions, as well as a high end ponytail that resembles a pineapple with the exception of a long strand of hair on the right side of her face. She wore elegant red and purple japanese clothes and carried four katanas. "Besides, most of the Krogan clans here are more peaceful, by their standards, due to that Urdnot Wrex guy. And apparently he helped save the galaxy!" she laughed "What a badass! Don't you think so, Sora?"

The one called Sora, who was in the middle of munching his marshmallow, was a 15-year old teenager whose most prominent physical traits were his spiky brown hair, deep blue eyes and a silver crown pendant that he always wear. He wore black, red and yellow clothes that includes a sleeveless t-shirt, a short-sleeved hooded jacket and baggy pants.

"Uh?" said confused the boy "Sorry, Miya. I was thinking about how my friends couldn't come here. I wasn't paying attention."

"You said that they were busy, right?" the first swordswoman asked.

"Yeah." he sighed "Kairi's family is busy with some thing related to the mayors of other islands, while Riku is helping the king with a Heartless invasion that's been happening at some underprepared worlds, and Donald and Goofy are with their families in a cruise they won at the lottery. And I couldn't invite the rest of my friends here for risk at breaking the World Order or just endangering their lives." he shrugged "At least my mother was out this weekend, so I didn't have anything better to do."

"Uh, bummer. That made me wish that I brought someone from Chaldea, but I don't know if Ritsuka and the others are able to come here." the second swordswoman, 'Miya', mused while scratching her head "What about your parents, Ciri? Would they have loved to come with you here?"

Ciri scoffed "Good luck trying anything short of force to convince Geralt. He hates teleporting with a passion. And Yennefer was making plans for their wedding anniversary. She… wouldn't want to celebrate it in a desolate wasteland. She says that she has bad memories about them."

Miya and Sora oh'd at the same time.

After some seconds of awkward silence, Sora smiled "Congratulations for them, I guess. It's a pity that we couldn't meet him. From what you told us about him, he may be harsh but he has a good heart. Maybe he could teach me some trick or two, either with those Witcher magic Signs or the sword." Ciri couldn't help but chuckle. Sora's enthusiasm was contagious, that and she also idolizes her surrogate father.

"Yeah, and I would like to duel him some day." said Miya with a huge grin of her own, her love of sword fights palpable in the air.

"Musashi!" exclaimed Ciri terrified "My father may be a skilled Witcher but you're a monster of the sword and a Heroic Spirit. You'd kill him!"

"Oi, oi, oi!" Miya, or Miyamoto Musashi, tried to calm down Ciri "Don't panic here, Ciri! Besides, I would limit myself and Witchers are superhuman (and I myself faced against Servants while alive, nearly died at those times, but meh), so no one would be seriously hurt, right?"

"Tell that to me." At Sora's grumpy tone, Miya's face adopted an uneasy and strained smile "Even after our spar, I needed some Elixirs as well as various Curagas to recover, and the aches and pains still endured for three days. At least you didn't have magic, like Sephiroth or that armor, or I would be worse."

"Ehehe…" Miya sheepishly rubbed her head under the accusing stares of Ciri and Sora "Well, you were Servant grade so I needed to go all out, so… But that weird armor you spoke of also kicked my ass! Not only it had a transforming Keyblade but was also able to seal my Noble Phantasm and was as fast as a grade-A Lancer. Not to say that it hits like a Berserker! And, and-!" While Miya was trying to dig herself out of that hole, she spotted someone coming towards them and her salvation "Hey, is that Nep here?"

Ciri and Sora turned their heads towards the direction the alternate version of the legendary swordsman pointed at. They saw another young woman, this one a few years older than Sora. She had purple eyes and long lilac hair with a pair of black D-pad hair-clips. She wears a black and purple black parka dress and shoes and no pants. Neither bra. She also wears a black and purple gun holder on her left thigh that was enchanted to automatically fit with any handgun that is holstered there, in this case a M-6 Carnifex.

Right now she was singing some kind of song with only "Nepu Nepu" as the lyrics while jovially walking towards the camping group as if she didn't go for a night walk in what is essentially a death world.

The Krogan would be proud of her or just think of her as a madwoman, and there were justified reasons for those two perspectives.

But in reality, she's just an airhead. An adorable airhead who can kick major ass with a pistol and dual blades and loves bugs.

Oh, and she can somehow summon giant pudding to flatten any incredulous and unfortunate schmuck caught by it.

"Hey! Neptune!" Sora called her, Neptune responding with a cheery wave and came running towards her sitting spot, summoning a stick so she could roast her own marshmallow.

"How was your walk, Neptune?" asked Ciri while shooting a final glare at Miya, who nervously averted her head. "With what we heard about the planet, there would be bound to be something trying to kill you."

"Yep, Ciri Ciri!" Neptune affirmed "There was hell outta monsters out there. Luckily I am a deuteragonist so I kicked their butts. And I could test this new baby." She caressed the Carnifex in her possession as if it were a puppy "Normal bullets and energy weapons are cool and all but the mass whatever ones are the best in my opinion. Who knew a supersonic tungsten sand grain was able to pack that much of a punch? And the ammo can be modded in an instant! Though I wish they could change the thermal venting system, those thermal clips destroy the gimmick of unlimited ammo." she pouted at the end.

"That's because the old cooldown system was too slow and much more prone to sabotaging." A feminine voice came from a purple book that magically appeared to Neptune's side while she was blissfully enjoying her sweet campfire snack "But yeah, is stupid in the sense of nerfing the virtually unlimited ammo."

"But doesn't Neptune's skills give her guns much more ammo than they could hold?" Miya asked with a raised eyebrow.

"That's the point." Neptune adopted Teaching Pose Number XX (waving the index finger willy-nilly with cartoonish spiral glasses that she somehow put on her face) "What could happen if I were to run out of bullets in the middle of a special attack, or if it jammed, that would be silly! Though I think that could probably happen in a parody like Gintama or something…" Neptune trailed off until she remembered something, leaving her with anime white circle eyes "Oh, I nearly forgot! We found a Thresher Maw or something that resembled one!"

"Whoa, did you find one?!" Sora asked with the enthusiasm of a child that discovered something awesome "Wait, what do you mean with something?"

"To put it bluntly, it put any regular Thresher Maw to shame. It was Kaiju size for fuck's sake!" the book answered "If it were to take interest on us we wouldn't have an opportunity to escape away unscathed."

"It seems to me that you found Kalros." an unknown voice sounded out, freaking out our swordswomen(and man).

The owner of the voice was a Krogan, possessor of blue eyes and seemingly young by the race's standards due to the segmented crest of his head and the smoothness of his skin.

"Oh geez! Just where the hell did you come from?!" shouted Miya, who like the others, was ready to bring out her weapons.

"I was just taking a walk when I saw an unarmored human girl." the Krogan said while pointing at Neptune, who had a sheepish face "That would mean she was confident in her abilities or just a complete moron." Neptune's face was now sheepier "So I followed her just in case. By the way, good response, though if it were a more sneakier foe, at least one of you would have died, like many more overconfident Krogan." he commented upon the others' reactive actions while scoffing at the last part. "My apologies."

"Don't worry. Most of us are accustomed to ambushes. Though we are fairly away from any clan territory, I would not have expected any Krogan to show up here, much less a polite one." Ciri said relaxing a bit but not completely in the presence of a possible enemy.

"Hmph! You've done your homework, I see. And you carry yourself like a hunter, and the others as warriors, though I can't say much about the purple one."

"Mou! I am a kickass warrior too! It just happens that there isn't anyone to kick their ass!"

"And yet you act as a brat." the book remarked "Even samurai hobo and keyboy are more mature than you, despite their simple-mindedness."

""Hey!"" Said simpletons took offense at that.

The Krogan took a hearty laugh "What a bunch! Reminds me of Shepard and the Normandy's crew!"

"Wait, you know Shepard?" the swordswoman of the void asked "The galactic hero?"

"Know him? I'll let you know that there hasn't been a battlemaster worthier than him. He not only helped liberate the Krogan of the genophage's curse, victoriously rallied the galaxy against the indomitable might of the Reapers and became brother of Urdnot Wrex in the fires of battle. He helped me dominate my blood's fury and given me a greater purpose. Not even the greatest warlords of the past can come close to that." said the Krogan with utmost pride in his voice.

"Wow, that must have been quite a honor." said Sora awed, and he knew a fair share of inspiring heroes.

"Indeed it was." the Krogan nodded, however his omnitool rang out.

"Where are you Grunt? We're going to start the barbecue and we can't begin with you!" a male and charismatic voice sounded out, like a father would to his son, while the background was filled with laughs, shouts and calibration memes.

"Don't worry Shepard, I'm on my way" the Krogan, Grunt, answered "I'm sorry, but I should go. You're not the only group of non-Krogan crazy and strong enough to camp out in the wilderness that is Tuchanka."

"Oh, don't worry!" Neptune said "After all, the star appearance of a cameo character is always welcome, no matter their screen time! Despite this being a fanfic…"

Grunt raised the Krogan equivalent of an eyebrow and looked towards the rest of the group, who shrugged. That's how Neptune always is, for bad or good.

"Wait!" Sora shouted before the Krogan went his way "We didn't present ourselves. I'm Sora."

"Ciri."

"I am the awesome samurai Miyamoto Mushashi!"

"And I am the even more awesome protagonist Neppppptuuuuuuuune!"

"Oi! Don't steal my thunder, Nep!"

Grunt laughed once more "Then I'm Urdnot Grunt, true Krogan at the service of Shepard's krant and the Urdnot clan. May we cross paths once more, whether in times of peace or together at the battlefield."

And thus, Grunt left, on his way to one of the infamously crazy parties the Normandy ex-crew was known for. Will they meet again with this equally disparate quartet? Maybe, the author doesn't know he will write out something like that or not.

Now at our protagonists camp, the sword fighters are excited. That was the magic of world travelling, you can meet new and varied cultures; rivalries and friendships created in the most varied of situations; and epic adventures as well as nonsensical shenanigans to occur in an infinite of possibilities.

"So" Ciri let out "Who's taking care of first watch?"

Let's say that Tuchanka's landscape gained a few more scars, consequence of a trivial and highly destructive selection match.

Such is the Tuchankan way.

AN: Yeah, I just thought of dimensional travelers and sword users and this came out, so now, the disparate universes of Neptunia, Fate, The Witcher and Kingdom Hearts unite/clash together to create unforgettable relationships and epic battles. This fic will be a series of connected one-shots that treat about those unique verses meeting each other in their own settings or in a completely different universe.

I will be open to ideas that you send, whether is a specific scenario or just characters meeting each other, and there's a huge amount of them.

The timelines of each universe:

-Kingdom Hearts: after KH2 but before DDD.

-Witcher: after the Wild Hunt videogame.

-Fate: the Grand Order timeline, after Shimosa.

-Neptunia: after Megadimension Neptunia VII/VIIR.

Just in case, I didn't play or just didn't finish all of those games, so my main source of information are wikis, fanfics and gameplays.
