As I thought of how to begin, I remembered when Spike found out about my human and old pony life as Twilight Tempest Sparkle, Daughter of Luna and Selene Di Amour.

My human soul had not yet entered Twilight's body, but Truth transferred my human memories into the new vessel so that it could adjust to the transfer. This is why I could tell Spike, who I would become in the first place.

The day was June third, according to Equus’ calendar, not Earth's. Spike had just made breakfast when my memory entered Twilight's body. As the day wore on, some of the memories which had been blocked in Twilight began to leak through as the human soul began integrating with Twilight’s body This caused me to start acting differently as some basic form of my consciousness began to awaken in my new body.

"Hey, Twilight are you okay? You're staring at the hourglass pretty hard. It’s as if you see something in the reflections that I can't ."

Spike was right. I could see things in the reflections, while he couldn't. Aunty ‘Tia and my Moms had used the hourglass before my Moms fusion and fall. ‘Tia had brought it with her when she moved as it had a shit ton of their magic absorbed into the frame and the sand inside of the hourglass and as such it could show any member of their immediate family thing they couldn't see anywhere else.

What I saw was my human soul slowly filling in my new body, but that wasn't the only thing going on at that time. I watched as my memories from when I was a human play before me, from the moment I left my human mother’s womb to Truth transferring my incorporeal self into Twilight’s body. It’s strange and not a little confusing, having multiple personalities. You wonder which is the original personality of the body in which you reside and other questions such as the other personalities being real living beings that somehow got trapped in your head, or if they’re not ‘real’ but coping mechanisms produced by a broken mind. Was I Twilight receiving the human memories into my body? Was I, the human, invading Twilight’s body and receiving her memories? Had either of us been real? Or were we just fictional personalities produced by a broken mind? I didn’t know the answer to these thoughts I had been having, but real or not, these memories were being integrated and accepted into my new body. As I watched the film-like memories, I told Spike I would show him what I was seeing.

Casting a slight variant of the image projection spell I had learned to help me study, Spike saw my old lives as I had seen them in the hourglass. We both sat there watching for hours as my human and alicorn lives played on the glass first my human life as that was the shorter of the two personality memories which was played. It took approximately an hour for my human soul to complete the integration process and filling my body. When that finished my human soul fell into a sort of hibernation as it adjusted itself to its new home. This caused the scene in the hourglass to Shift to my earliest memories, the ones of my birth and my alicorn life of 1,500 years.

The whole thing flashed by for us both, but it was just my memories returning to their home, not a movie production from Hollywood.

When the last images played out on the glass surface I sensed Spike's questions.

" I can tell what you're about to ask me, my son," I said before he could start to pelt me with his queries. "What we just saw was my past lives and the memories of both lifetimes returning to me."

Spike just sat there, his jaw dropped at my use of formal language and the word ‘son.’

"Y-you just called me 'Son,' not 'Little Brother,' not 'Your Number One Assistant,' but 'Son'! he shouted at me "Who are you and what have you done with my big sister! Where is Twilight, huh!? Where! Tell me! Tell me before I send a letter to the Princess reporting you! You bucking imposter!" Spike’s body grew with his fury and started glowing as he summoned up his flame, to which I called out:

"Spike Alabaster Crone Sparkle! Watch your fucking language!" I started shifting into my alicorn form and grew to match his 6' height as my backpack appeared on my back and I pulled out my dual load pistols. I clicked my safeties to tranquilizer darts and aimed for his chest if I couldn't calm him down.

But it seems the rage dissipated when I used both his middle names "Alabaster Crone Sparkle, only our family knows that name," he said remaining his current height despite him not being filled with rage at the moment. I suspect he did like I did when I was human, he put anger on a low simmer to keep up that size. "Okay, you really are Twilight, but somehow you're also a lot older than you look."

"Hey," I scoffed as I lowered my guns and switched the safeties back on, "Rude much? I'm still only 23 in this body! It's my souls that are older."

"Souls?!" he asked, "You have more than one?"

"Five of them actually, I have the human, Dakota, and me, Twilight Tempest Sparkle or Tempe for short, Nightmare Nova, and Cristal. Each soul looks different in life and I can Shift between them or combine them to increase my abilities, though Shifting past this state, is dangerous. Even here, Aunty Tia could sense the Flare in power it takes for me to shift further. The only reason I'm like this now is that over there." I pointed to the hourglass with my thumb. "That hourglass was once in the old capital Cantorlot in Moms' and Tia's office when the two would switch shifts one would flip the glass over using magic. Over the centuries, this went on, until this absorbed so much of their magic that all they needed to do was think of the glass flipping and it would on its own. the glass frame and sand inside still hold a shit ton of their magic. This imbued magic creates many interesting effects," I paused to take a breath before continuing. "Such as the memories we saw playing on the glass' surface and a damping field that covers this tower and that hides most of my magic from being sensed by anypony, even Aunty Celestia. I'll have to recast my old glamor before we leave on the 20th. I hope it's still as powerful as I remember."

"Woah, woah, woah! Wait for a just a second! Your aunt is Celestia?" Spike asked bewildered. I nodded "If that's true who are your original parents?"

“Luna and Selene Di Amour, the Night Alicorns,” I stated plainly as I put away my pistols thankful of their dual ammo typing. The .22lr ammo would have just bounced off his hardened scales.

"Night Alicorns?! I thought Celestia ruled over the night and the day. how can there be Night Alicorns?"

"How much history have I taught you?" I said as I checked my bag for my phone and my radio.

"Not much. But what does that have to do with all of this," Spike said as he gestured at me and my bag. "And what is that?"

"This is what humans call a backpack. Mine is an A-frame type made for camping and carrying a large amount of stuff inside." I said as I rummaged around inside said pack finding things I never put inside. 'Huh, what's this? Did Truth leave me a note? That cheeky bastard.' I thought as I found the note in the inner pocket next to a pill case filled with different types of things I collected over the years.

Dakota/Twilight Aurora Sparkle,

If you're reading this then you've received my gifts. Good, the items inside here have been placed inside for both of you.

Dakota, you know that any who enter my realm have to give something to leave. in you case, I removed the limiter on the human magic and the blockers that kept you from using said magic to its fullest.

Twilight, I also took something from you, but like Dakota it was actually a benefit. Instead of you freaking out over little things you will now deal with problems and crises better. That's right I took Twi-crazy from you. Along with something else that was limiting you. Literally. I took your magic limiter so now you can access all magic as your Elements were meant to do.

I only took these things because yours was a special case as you both were already aware of me and the fact that Dakota is a fucking brutal bargainer even with divine beings like me.

The items I placed inside your bag are as follows:

One miniaturized library of hand casting spells, a laptop that connects to the Omniversal internet, a bunch of ammo of various types for your guns, some meat cooking implements, a book on Caribou anatomy, magical resistances, and how to counteract them and my personal favorite a book on alchemy as used in FMA.

Have fun and tell your family I said hi,

Truth

Ps. I'll drop stuff in the bag from time to time so look inside often.

'So that's why he sent me the hand casting spells. In case I find unicorns without horns they can heal themselves.'

"Twilight, Twilight you there!" Spike said as I stood there reading the note. "You still haven't told me about Night Alicorns yet."

"Oh sorry, I just got some news that pertains to that," I said as I placed the note back in the pocket I found it in.

"Back before the summer sun, there were two sisters who had ruled the land together, Celestia and Luna. The two sisters were both alicorns, one of the sun and one of the moon.

One night the younger sister Luna was raising the moon when she felt another help her bring the moon to its zenith. At first, she thought her sister was the one to help as she still had trouble with the moon alone sometimes, so she dismissed the strange occurrence, but the same thing happened the next night and again the next. Luna knew her sister wasn't the one who was helping her by the sixth night as she had Celestia raise the moon while she guided it that night and still felt another help. she had told Celestia that she would be gone for a time as she needed rest for a long journey. Celestia knew Luna asked for help that night for that reason as she was still young for an alicorn and needed rest more often because of it. What she didn't know was the real reason for the request was so Luna could track the other being who had helped her for the last six nights.

When Luna left the Everfree castle to find whoever helped her she took no guard as she wanted to meet this pony alone. And a contingent of guards would be in the way no matter how far they strayed from her." I paused to take a breath and to make sure my son was still awake. To my surprise, he was still 6' tall and wide awake. I thought me lecturing him on how my parents met and how Nightmare was formed would at least calm him down enough to cause him to shrink, but I guess he could stay that tall if he wanted to indefinitely.

"Go on," he said as he did that same gesture with his right claws. "You're clearly not finished telling me how the two met, so go on."

"Ok, okay," I said before I continued. "Luna followed the magic trail created by this mysterious Alicorn as to move the sun or the moon alone or with two ponies needed alicorn magic. What she found was a black coated Alicorn mare about her size and height. Her mane and tail were black with stars inside looking like deep space and they flowed like water in a nonexistent current not too dissimilar to her own mane and tail's breeze-like flowing but smoother almost as if they were made of true liquid instead of hair.

As Luna flew in closer she noticed that her earlier observations had been mistaken. The mare's coat wasn't a true black but a very deep purple that from a distance appeared black. But on closer inspection was, in fact, was the color of the sky in the darkest parts of the night.

When she landed Luna noticed more about the mare. her eyes were a deep cerulean green. Her Cutiemark was a full moon with six-pointed stars surrounding it. Though Luna originally thought the mare was her height she actually appeared slightly taller and heavier in a muscular kind of way and she also seemed to have longer wings as well.

When Luna approached the mare she smiled showing canines and omnivorous teeth to which Luna smiled back showing her own omnivorous set. Knowing they both could control the night they introduced themselves. That's when Luna learned the mare's name 'Selene DI Amour, the lost Alicorn of the Night.'

As Luna and Selene talked they both learned things about each other. Luna stayed with Selene for a fortnight, but she soon had to return to the Everfree castle.

In that time the two had fallen in love and couldn't bear to leave the other alone so Luna brought Selene with her. But before landing, she hit Selene with a powerful invisibility spell as she was worried about what Celestia would say. Celestia had just broken up with her coltfriend a few months before and wasn't taking the pain well so Luna thought that her finding love would hurt her heartbroken sister worse at that time.

For a couple of years, both Luna and Selene had a happy life but then he came and created the worst Nightmare ever.

Discord had landed on Equisian shores and found harmony everywhere. This disgusted him and made him mad with rage. He started small changing one or two ponies at a time to increase his magic but Selene wasn't having it. When she dream-walked into the mind of a pony Disord had changed her rage didn't just match Discord's but overpowered it. She brought her findings to Luna, but Discord had tracked Selene through the mind of the pony and appeared before both of the night alicorns and used his magic to fuse their bodies and minds into one being thus creating his own downfall as Selene knew his weakness was harmony.

As the two recovered, Disord took over Equestria and Celestia tried to talk to him. For a time it seemed like it would work but then Disord just threw the three alicorns out of the Everfree with his magic. When Luna, Selene, and Celestia landed, Discord's true takeover took place.
He spread his influence over most of the planet and by then I had started forming from the leftover magic and mass that the fusion created.
(the rainbow maned alicorn construct in rainbow rocks)

Celestia and the fused lovers had almost reached the Tree of Harmony by this point. Where I lay as the Elements of Destiny and Magic linked to my soul. When the Alicorns entered the cave with the tree I used my power to hide inside the element of magic until they used them to seal Discord in stone.

When that happened, the Chaos magic that fused the two Night Alicorns together became unstable and caused both Luna and Selene to start falling into a depression leading to insanity.

After the battle, I found myself as a newborn filly in Luna and Selene's room. My mind was wiped of anything prior to the employment of the Elements, which had given birth to me, but I remained an alicorn. When Luna and Selene returned they found me just sitting there looking at them then I said my first word, 'Mommas?'

The rest you've seen, Spike. I think you get now why I have been acting strange today."

“That still doesn't explain much. Though I did see your past lives so you don't need to explain much more anyway. but I still have one question."

"Oh, and what's that?"

"Why did you call me son?”

"Well, I hatched you from your egg. Kinda makes me your mom now doesn't it?"

"True. But it makes me wonder am I your son or your little brother?"

"A bit of both I think. Seeing as I was only 8 when you hatched."

"Yeah, eight is kinda young to be a full-fledged mother, huh?"

“Yeah.” I chuckled.

Over the days following I told Spike more things about my human and alicorn lives. I relearned old spells and combat techniques I had forgotten in preparation for the Caribou landing in Equestria. As nopony but I and Spike knew of my alicorn form at this point, one of the spells I relearned was a glamor I used whenever I had to leave moms' room back in the day it was so strong it hid my alicorn power and wings from even Tia's Sight. Though it turns out I had somehow cast a sealing spell on my wings as a kid and I had to break that first.
I checked my bag as Truth suggested and every three to five hours I found books about human magic and other powers I could learn to use from other worlds. In my off time, I practiced the alchemy that Truth's book taught me. It seemed he put Ed's sacrifice to good use as I found that the book was all of Edward Elric's alchemy knowledge and more.

Spike asked if I liked red meat now as the saw that my teeth had changed slightly. Most unicorns need fish in their diet as they need the extra protein for magic casting. Alicorns need actual red meat as the magic we produce is more potent which in turn demands more out of us. I told him I always had but I used to fear this enjoyment as ponies only eat fish as most animals are somewhat sentient. Luckily he had looked this up as his new size demanded more food to keep up with the increase in energy and power - that's why he is 5' right now he doesn't have any jerky on him to maintain his 6' height. We both ate the last of it two days before- and found that only animals inside the continent of Equestria have sentience due to the high amount of harmony magic and as such omnivorous races like the Griffins and Diamond Dogs hunt on the islands outside the magic's reach where the majority of non-speaking animals didn't have any sentience. These animals are turned into jerky for transport on the continent and are sold as strips for any meat-eating race to enjoy.

As we prepared for the Summer Sun Festival I told Spike some of what would happen and taught him to fight in hand to hand with his claws. As we sparred he started calling me by my human name. I had told him all about my human world. Sunset had left for a true mirror of Equestria in human form not my world and he liked what my human name means Dakota: Lakota-Sioux for ‘beautiful moon rising’ as I was told by my mother in my human world. (I've never met any Lakota so I'm not sure please tell me if I'm wrong and if so I'm truly sorry) He also sometimes called me mom which made my heart soar.

Then came the day my human soul awoke the 20th of June we had been preparing for this for the past three days and Spike helped me adjust as Dakota's mind took over the first time. All this flashed through my mind as I got ready to tell the mares in front of me about my life up to the point.

"Okay, let's begin,’ I said as I smiled at them.

Author's Notes:
