Chronologically, this falls 5 years after the defeat of Cozy, Tirek, and Chrysalis. And also 5 years before Earnest Empathetic Change begins.
Just like the story where Nova Spark met up with Geniequestria Starlight, this serves as a B-canon in that it's canon if you want it to be. But won't likely effect stuff outside this story. We brainstormed and wrote this together, while my friend did all the supporting art for this))
Sunset would be able to hear Nova and Fury gasp at their new appearance.
Nova: (W-woah! We got more traits than expected! I think we look pretty good! And even though neither Fury or I am in control… I feel more powerful than ever! Look, even our cutie mark changed, remarkable! This is less assimilation and more of a fusion!)
The senses that were now returned to Sunset for the first time in years, combined with their newfound magical power. It was as if they were a brand new pony!
Nova: (Hahaha! We're so happy for you, Sunset! I told you it was possible to make this work!)
Nova: (Even… if I was on the verge of almost giving up. We pulled through in the end! Hah, place your bets, who will freak out first when they see us. Twilight or Starlight? My bet's on Twilight considering Starlight hasn't met us yet.)
Sunset didn't have much reason to doubt Nova as she mentioned it in their discussion within the mind. But to actually feel blood coursing through her veins again, real skin and flesh. It felt odd after being a spirit for so long. But it nonetheless felt great. There was one thing she had to do now...
Sunset walked on over to the section covering her death. Looked at the figures of her murderers, and conjured a five fingered hand. Flipping the bird at them.
Sunset: HA! Take that, you good for nothing flankholes! I'm back! Hahahahaha!
She knew it wasn't really them, and she thanks goodness it isn't. But it was satisfying nonetheless
Both Nova and Fury were somewhat taken aback by Sunset's first action in their body, cursing out her murderers. But considering they got to feel her emotions and pain not too long ago, this was understandable.
Fury: (Ha! You tell em! You can now come back and they NEVER will! Oh and Nova, I'm jumping in on that bet, Starlight will freak out first. I mean she'll actually get to hug her mom for the first time even if it's a different body. I think that holds more precedence.)
Sunset: (A bit of a correction there, Fury. Starlight was able to hug me as a spirit, but our first actual hug in real bodies will certainly be... something special.)
Fury: (Ah I see, well my point still stands though!)
Sunset herself begins to get a feel for the power. She shivers with the magic coursing through her body.
Sunset: Wow... how strong are we now...? I've felt what it's like to have power... but I could almost swear this dwarfs even my own power in my prime... You don't think... that this fusion made us a... half-spirit like Twilight. Not exactly a genie since the 'vessel' is you Nova, but still some of the same abilities. If it's true, we might have the ability to shift our backside into a ghostly tail and fly like that. Do you girls want to give that a try to test it out?
And if that works... even wishes might be on the table!
Sunset does raise a good question about their power. It doesn't just feel like one was added to the other, rather it felt like it had multiplied! So it's no wonder why Nova had struggled to hold it in. Nova paces around in their mind to think.
Nova: (I...suppose the process is far more in depth than we could have realized. This is new ground for all of us. I hadn't even thought we'd have magical power like this. But just look at our mane for example, it moves like Celestia or Luna's does! If we're half spirit in the technical sense... )
A wide grin comes across her face as Sunset is also putting things together.
Nova: (It's a shame we don't get the attire but being an equivalent to a genie!? Hahaha! With spiritual power and potentially wish granting abilities!?! You think either of us are going to say no to some test runs?! Fury, you ready to show the world what we're capable of?)
Fury gives as big of a grin
Fury: (Are you kidding? I'm more than ready, though just remember, it's ultimately up to Sunset as she's the one in control. But you can deal with that, can't you?)
She asks in a teasing tone
Nova grumbles, knowing that the lack of control does usually bother her.
Nova: (Hmph! I-I'll be fine! We can still feel all the power from within here so it's fine, especially with Sunset at the helm! I'm sure we uh… we'd be quite reckless with it. Though I won't lie, I do want to know what our maximum power is right now, this just feels incredible! Nothing like what we've ever felt before!)
Sunset: If this works, I'll only do a quick fly through the museum. Don't want to freak out all of Sire's Hollow with a random pony they might not even recognize that it's me and/or Nova right away. But alright, let's try this...
Sunset takes a deep breath focusing some magic, something of a spiritual aura seems to surround them as they get to use the magic of a spirit for the first time. Sunset levitates off the ground, and mid-air she places her hindlegs parallel to each other.. She then gently moves them up and down, simulating a bit of a wave, soon her tail and the end of her hooves give way, starting to merge and stretch. Slowly moving up until it stops at just below their hips. A relaxing feeling washed over all three of them inside as they use their magic to defy gravity.
Sunset: Well, would you look at that! It worked!
Sunset flies around the museum exhibits. Her life flashing before her eyes... in a literal sense. As she circles pass her life's memorabilia over and over again.
Nova: That sounds reasonable, and there's more than enough space for a test flight.
Both Nova and Fury seem excited to see if this will work, but what they didn't expect was that the magic Sunset was channeling would affect them within the mindscape! They gained an aura around them as well as Sunset used their magic. A blue one for Nova and a red one for Fury, they too began to levitate as the magic coursed through their body!
Nova: (W-woah! Fury, we're flying!! And uh oooh, this actually doesn't feel too bad! Is this what it's like to be a spirit? The lack of hindlegs takes a moment to get used to but… I don't hate it!)
Like Sunset was doing on the outside, Nova and Fury began to fly around inside their head.
Fury: (This is insane! I feel lighter than ever and yet so relaxed too. Look at our auras!)
Fury said in an amazed tone
Fury: (Sunset, this is incredible, our body is holding up just fine too, yeah? Hey see if we can go through walls like you did!]
Going past all of the exhibits once more, a thought popped into Nova's head
Nova: (Hey, you think with the discoveries we make in the next few days, we'll have to add a new section to your museum? I mean these findings are going to be massive for all of Equestria! If this is what's happening to us, we may have just stumbled onto how ponies can use spirit magic for themselves!!)
Sunset stops herself to think about what Nova said.
Sunset: That seems like something we'd have to be careful with however. We can't just let EVERYPONY get a spirit inside them. They'd have to be trustworthy, on nearly the same level of making sure they'd be responsible like how genies of Saddle Arabia in the past vetted ponies that would use their power responsibly.
And even besides that, Dragon Tears are still rare. It's not even a 100% guarantee that a dragon who dies will drop one.
That said, I suppose I wouldn't mind an eventual ‘Sunset returns!’ section eventually.
Nova: (Hmm… that's actually a fair point, if everypony had unfiltered access it could lead to the rise of a more powerful villain and we don't need any more of those. But it's still something worth looking into. From what I've been told about the other elements of harmony bearers for example. I believe the element of Honesty, Applejack, would find this to be beneficial. But as much as I don't want to admit it. We'd probably need to run this by Twilight to prevent spirit magic from getting into the wrong hooves. And also make sure with the summoned spirits that it's not a permanent revival either. I don't think there are many other ponies like us either that understand their own heads and mindspaces. It could get sticky fast....)
She sounds disappointed at first but perks up moments later
Nova: (But just imagine the possibilities!! And we're going to see her right now anyway so I guess we'll know how she feels soon enough.)
As Nova suggests going through walls, Sunset remembered that she could touch the wall earlier when she was first trying out her new live body. She knows she'll probably crash if she flew into as she is now. Sunset's happy to be alive in some capacity but she's not looking forward to feeling pain again. And she should also be careful because this isn't her own body. However, with the power coursing through their veins. She thinks of another way. She charges her horn, enveloping herself as her opaqueness fades into transparency. THAT'S when she tries to go through a wall. And it works perfectly.
Sunset: It takes a bit of 'Going Ghost' first but we certainly can!
Nova and Fury internally brace for an impact, they do trust Sunset, but given that she's still getting used to a body and the fact that they weren't sure if this would work, they wanted to be careful. But they look in awe as Sunset cast a spell allowing them to phase through easily
Fury: (Watching Sunset in action like this it's incredible. I didn't even know such a spell existed. Look at that, you're still able to teach us new tricks and with our own body too!)
Nova: (I KNOW RIGHT?! Fury, we need to be sure to take note of all these spells! It doesn't matter if we will or won't be able to cast them ourselves when we separate but it's something to work towards! Hehehe actually… you wanna give the receptionist one more jolt before we head out, Sunset?)
Sunset giggles about spooking the receptionist again.
Sunset: As fun as that would be, I think I'll be nice and spare her another scare. It might even be worse since she might not even recognize us now. She's willing to forgive me... most of the time... but not if she doesn't recognize that I'm half of what's scaring her.
Sunset also flies back down onto the ground. Reverting the ghostly tail back to her and Nova's tail and hindlegs. Satisfied enough with that test.
Nova and Fury sigh, but Sunset is right. The receptionist didn't seem too fond of them already so to scare them now that they're unrecognizable seems like a poor choice. When Sunset undoes the magic that allowed her to fly, both Nova and Fury find themselves back to normal as well.
Nova: (Huh, that's interesting we've got our legs back. Fury, you're used to being in here more than I am. Is this normally what happens to you when I take on a new form?)
Fury: (Kind of? Honestly, with Sunset in charge it feels different. Not bad, but just different.)
Sunset: Say I wonder when Twilight's coming ba-
As if on cue, a portal opens up not far from where Sunset was standing. Twilight has her eyes closed with a smile.
Twilight: I'm back Nova and Sunset! I checked on Spike and he's holding up pretty well, I'm so proud of my boy! What have you two be... en... up... to....?
She opened her eyes as the end of her sentence trailed off. Immediately, seeing not two ponies. But just one, her eyes widen as she can clearly tell there's both Sunset and Nova traits... And her right eye twitches....
Sunset: (Oh boy... incoming Twilighting!)
When Twilight pops back into the museum, Nova can't help but cheer that she's seemingly won her little bet.
Nova: (HAH I CALLED IT! YES! I love it when I'm right! She might try to undo this by the way, but....actually we're kind of on an even playing field with her now aren't we? Hehehehehe!! That look on her face, oh I will not be forgetting it any time soon! Oohh ooh Sunset, you should try acting like me, go along with the bit! I haven't told Twilight anything about this experiment so she probably thinks I'm still in charge. Just make sure to call her by her last name to be convincing!)
Fury rolls her eyes, but she can't help but laugh along with Nova as well
Fury: (Alright alright, you win but who knows, Starlight could come in any second and we get the student teacher freakout!)
Twilight: WHAT THE ACTUAL HAY?! Nova! Did you just... ABSORB Sunset?!
