Discord frowned “What you are about to see might be quite unsettling?’

Twilight frowned “When does this happen?”

Discord grimaced “This happens a while after they joined the Night Sentinels.”

Fluttershy raised an eyebrow “What could be worse than what we have already seen so far?”

Celestia frowned, “Well we better tear off the bandaid now, we’ll deal with it later.”

Discord sighed “Alright.” He started the projection once more

Sunset

Soldier now known as the Slayer awoke, snapping his metal bindings before slamming a possessed human's head into the side of the sarcophagus he found himself in. He stood up picking up a small plasma pistol as he saw three similar possessed standing around a giant container field with a chaotic red energy, Sunset floating in the centre.

Slayer boiled with rage, grabbing two of the possessed, shattering their skulls. The third didn’t have time to react before being similarly dispatched. Slayer then slammed his fist into the container shattering it, as the energy burst out Sunset’s eyes opened.

Sunset’s eyes opened and she began pulling the energy into herself, her body shifting in response to the energy. She screamed as two sharp horns started growing out of the top of head facing forward, wing frames bursting out of her back covered in blood. Her skin started to change to a deep crimson. As the pain started to fade, she stood up flaring a pair of pitch black wings with a crimson membrane between them.

Slayer eyed her carefully “Sunset, are you alright?”

Sunset groaned “Yeah, that hurt.” She then looked at her wings “I used to want a pair of wings so bad but didn’t ever expect to get a pair after I left home.” Sunset then blinked “Where is your armour?”

Slayer turned to the room next to them to see his armour. Once they approached the panel Slayer activated a playback of what happened with the leader saying “We have to contain this.” As four people were praying to the sarcophagus.

Sunset frowned “So they didn’t want you to escape.”

Slayer crossed his arms “But someone let me out of there somehow.” The two then head into the next room where Slayer puts on his armour.

All the ponies in the room were staring at Discord. Twilight shrieked “What was that!”

Discord grimaced “You don’t need to be so loud.” He then took a deep breath “Absorbing that much powerful energy at once caused her body to change to adapt to the influx of energy triggering an ascension.”

Celestia frowned “That would make her incredibly dangerous, a new Alicorn grows stronger over time. It takes a while for that power to become fully established.”

Discord crossed his arms “I suppose I should explain something about Alicorns, they are scaled in different forms which affects their appearance and power. Twilight is a one and has the potential to grow to a two and a half. Cadence is a one and a half while capable of becoming a two maybe a two point five. Celestia and Luna are twos. My power is about the equivalent of two and a half. The fully realised combined power of the Elements at their highest three point five.”

Luna blinked “Where does Sunset sit in all of this?”

Discord clenched his fist “Four at the minimum not accounting for future development of growth in power from here.”

Cadence shivered “S-she h-has t-that k-kind o-of p-power. I-I’m g-going t-to m-my r-room.” Cadence left the room in a hurry.

Fluttershy frowned at Discord “How do you know that?”

Discord grimaced “The demons have conquered countless universes before this one. The power they wield is formidable and Sunset was already capable of ripping them apart like tissue paper. Combining her magical power with Argent Energy makes her incredibly powerful.”

Twilight nodded “Well let’s see what happens next.” Discord nodded, starting the projection again.

Sunset

Sunset and Slayer turn to see a monitor that read “Dewmonic invasion in progress.”

Sunset growled “What wrong with it, stupid machine!”

Slayer frowned, starting the statue report. The machine tried and failed to scan, all the data was unavailable. Slayer frowned, “That’s not helping.” The machine then reported that the Satellite Dish Array was offline causing the fault.

After learning the cause of the fault a voice spoke “Welcome. I’m Dr Samuel Hayden. I’m the head of this facility. I think we can work together and resolve this problem in a way that benefits us both.”

Sunset tossed the panel aside “We’ll discuss this in person, I don’t trust this guy.” Slayer and Sunset turned to the door which opened. They passed the corpse of a dead guy. Sunset shrugged “Sucks to be him.”

There were a few possessed humans who Sunset and Slayer pounded into piles of blood. They then climbed the stairs, the Slayer picking up a combat shotgun. Sunset frowned “Do we really need weapons?”

The Slayer frowned “They make demons suffer more.” Sunset shrugged in response as they headed through the door.

An Imp leapt in through a broken window and mid scream Sunset silenced it ripping it’s spine out, blood dripping onto the floor. The duo then kept moving, heading into the next room and clearing it out with ease, including a weird portal thing. They kept hearing as they did so “Demonic presence at unsafe levels. Lockdown is in effect.”

Sunset blinked “How long have we been gone, that demonic presence has a safe level?’

Slayer grimaced, “I don’t know, something weird is going on here.”

The came another signal as they cleared out the last Imp “Demonic presence eliminated. Lockdown disengaged.” The two shook their heads before heading into the next room. They then entered another hallway with a projection that said “They can’t leave this place. It would ruin everything.”

Sunset grimaced “These humans must be using demonic power somehow. What idiots!” Slayer nodded in agreement. They then entered an elevator heading down.

They then heard Samuel Hayden’s voice again “I’m willing to take full responsibility for the horrible events of the last 24 hours but you must understand: our interest in their world was purely for the betterment of mankind. Everything has clearly gotten out of hand, yes, but it was worth the risk. I assure you.”

Sunset and Slayer clenched their fists before striking the device, shutting down the message. They then exited the elevator only to see what assumed was the desert surface of Mars. Sunset and the Slayer charged out into an abandoned facility, ripping the demonic inhabitants to shreds.

They find themselves at a door locked with a blue keycard, Sunset growled as she shatters the door “We are not doing this again!” They exited and arrived in another area. Sunset frowned as they destroyed more demons “Is this really what they are sending at us? These weaklings.”

Slayer frowned “This is not hell, they might be invading elsewhere. Let’s find where they are coming from.”

The duo head into an abandoned facility of some kind, they encounter a hologram that begins it’s speech. Sunset turns to Slayer “221 accident free days, doesn’t seem like it.” The Slayer nodded.

Sunset frowned as the Slayer paused for a second, he then shrugged “Just a message from a computer system called Vega, nothing to worry about.” They move forward killing more demons and finding an elevator with low power. The Slayer rips open a door before following him to kill more demons.They then reboot the power on a console up some stairs.

Then a woman turned up on one of the monitor’s “I believe in honesty, especially now, in what would be your final moments in this world. All the rumours, the human sacrifices, the Hell portal, , the demons…. it’s all… true. My sisters and brothers be thankful, you will be the first, you will have a seat alongside them just as I will in what would become the new world they will create for us…starting…now.”

Sunset glared at the computer “I will rip her soul out and torture for the next eternity.” They then return to the previous room picking a map on the way. After they hop down the elevator and slaughter more demons, they find a chainsaw which the Slayer takes.

Twilight frowned “Why does it seem less visceral?”

Discord frowned “All of this is taken from Sunset’s perspective. She has become used to killing demons and they don't really pose a threat to her anymore.”

Celestia sighed “Duty call. I will have to return to Canterlot. I have been away too long, I’ll say farewell to Candence before I leave.”

Fluttershy turned to Luna shortly after Celestia left “Are you okay?”

Luna sighed “I haven’t gotten over all of it. Some days I’m still very angry at her.”
Twilight blinked “I thought the elements fixed everything?”

Fluttershy raised an eyebrow “The elements are not a magical fix everything button. They suppressed Luna’s rage and power enough to allow Celestia and Luna to start the healing process but those feelings weren’t gone.”

Discord nodded “For the elements to do something that drastic there had to be no alternative. That is basically killing the pony who you were before and the Elements don’t do that except under the most dire of circumstances.”

Author's Note

I hope you don't mind the timeskip. Also I kept Dewmonic because I made that typo and thought it was funny so I kept it.
