It was near the lowest part in Sunset Shimmer's life. After a series of terrible choices, the once and former apprentice of Princess Celestia was little more than a declawed high school bully in the Human Realm. She'd been defeated by Princess Twilight Sparkle at the fall formal, and left to pick up the pieces of her life—with the help of her princess-assigned friends, of course. Unfortunately, the forgiveness of five girls means nothing next to a school full of people she's tormented for years.
After a foolhardy attempt by her former classmates to send Sunset 'home', the former unicorn has found herself stranded in a world she'd only heard tales of when she was a foal. Being transformed into a form capable of using magic once more should have been a blessing, but instead she's little more than an outlaw. Now she's found herself wrapped up in the adventures of the most wanted witch on the Boiling Isles, her adopted demon son, and a strange human girl from another Human Realm as she tries to find out if it's even possible to go back to her world, or barring that, Equestria.
Crossover with the Owl House focusing on a partially redeemed Sunset Shimmer that has been stuck right in the thick of things with the Owl House plot. How bad can one former unicorn screw things up?

Okay.... okay. Okay. Let's see where this one goes!

Hope you enjoy it. I've been having a blast writing it. Adapting and derailing things thus far has been the highlight of the last week or so for me. Working with a Sunset who hadn't yet had her full Rainbow Rocks redemption arc was too fun an idea to pass up, and I figured if depiction of Sunnybun would have anger issues, the second most likely would be one prior to RR. I'm definitely looking forward to reaching certain events in the show's lore, too. Got a whole bunch of things planned.
12112268
if the man himself is here, it must be good.
Hell of an entrance Sunset
Now to wait for the main cast
Welcome to the Isles Sunset
The price is your sanity
Keep up the amazing work
Oh Fates you cheeky gal, how did you know I'd just gotten into The Owl House? Can't wait to see where this goes!
12112548
The answer is that I have special powers that allow me to coincidentally do things that benefit others. Hope you enjoy 'Episode 2' when it gets released later this week.
Once you're done the series, if you end up really enjoying it, you ought to check out the Angel of the Owl House. It's an AU with massively expanded lore and some new twists, surrounding the idea of Luz and Camilla Noceda being angels, with Luz being a magically stunted cherub. It's long as all get-out and I'm not even done yet, but my god is it a good read.
12112559
Yeah I finished the show after a week of binging when i got into it a little over a month ago. Been poring over fan comics and writings on AO3 since then. There are definitely some great AUs out there. My favorites to date are probably Witch Among Humans and The Blight of Bonesborough. I'm a sucker for character redemtions, so I'm really looking forward to seeing Sunset interact with Amity later down the road.
It's honestly criminal how few MLP/TOH crossovers there are, including this one I've only seen a handful on this site.
12112570 I'm partway through the Blight of Bonesborough myself. Wasn't sure which Witch Among Humans one to go for though.
12112573
The Witch Among Humans story I've been reading through is this one. It's loosely based on MoringMark's comics of the AU. Pretty fun read so far.
12112582
I'll have to load that onto my ebook app. Thanks for the recommend.
Ooh - The Owl House is my second favorite show, after MLP of course! Can't wait to find out if Sunset Shimmer will join the Bad Girl Coven!
Ooh, excellent start! I'm hooked. I love TOH & MLP, so I'm excited to see how their intersection changes both.
My Little Pony: Apocalypse Pony! Punish mankind for their sins!
Interesting. It's been a while since I read a relatively serious fic where MLP:FiM characters exist alongside the MLP:FiM TV show - at least one written by someone with your
good grammarwriting caliber.I kind of expected Sunset to be more alarmed, or at least curious, about Luz knowing Sunset's life from watching it in a cartoon. I hope Sunset
interrogatesasks Luz about it soon, because that strikes me as the kind of thing that would be hard to ignore for long. It also introduces all kinds of joke and drama opportunities.(Edit: On reread, looks like Sunset's strategy is repressing/ignoring it to avoid an existential crisis. That's... actually pretty believable!)
Looking forward to the next chapter!
12112570
Preach!
This seems fun. I'm gonna stick around with this one
Hey, is that a reference?
This is one Fun Story
Okay you got my attention. Gonna see where this goes.
Interesting crossover. Your prose is actually pretty decent, and everyone seems mostly in-character. I like how you kept Sunset’s fiery temper in. She might be trying to be kinder, but her anger is still something she struggles with. I’m curious to know if we’ll have any scenes back in the EG universe? After that stunt the students pulled, I’d like to see them receive some consequences for their actions. Twilight’s reaction is certainly something I would like to see.
12112945
Ayep. Admittedly, it was just one of those stray thoughts that tickled me too much not to include it. In a chat I was in while writing the scene, someone actually went and referenced another scene. I can't believe every single one of them kicked you in the dick. Luckily, I had enough self-control not to work that reference in.
12112992
Funny enough, that's actually coming in two chapters.
You wanna add another tally to her magic cop beatdown, Lilith?
I am greatly looking forward to seeing where this goes!
So, is Sunset going to write Celestia anytime soon about finding a way home?
12113022
You'll just have to wait and see on Friday.
12113023
Yay!
Just started to rewatvh TOH and this fic appears, I'm whit the demon Dana, life it's a simulation
12112994
Look at the stories that i wrote, i have at least one reference per chapter.
Though, i haven't had the motivation the update them in a while…
No, this is not advertising, don't bother reading them if you don't like them, I'm just saying i understand the need to add funny references.
Pained Wheezing
Oo this is certainly very interesting... Cant wait to see how Sunset will change things >:3
Ok. I love this. I need to follow to see where this goes
12112281
KO this story is very good seeing Sunset in the Owl House universe after being kicked out by most of Canterlot High, and she is already making some new friends that could help. I hope the Rainbooms will make their appearance in the Boiling Isles along with Celestia. And hoping that Flash isn’t one of the students that threw her out of their world.
ISS?
Even so that could take months for all Sunset knows.
saying 'the most' twice doesn't seem right imo.
also, the mention of the rumor of Dash doing drugs sounds insane, I'm shocked Sunset did that. 
Holy shit, someone stole her clothes and everything, how cruel!!!
As much as I hate what the students are doing to her, I can understand why they're doing it sadly...
That's too far done!
Well shit.
At least there's no tears in reality, right?
Kinda surprised she knows about it tbt, but seeing this is an AU connected to the TOH timeline, I totally get that.
Lol on that last one. Totally get the reference despite I didn't see the show in question Amphibia.
Lol on the Avatar TLA reference, that never gets old, same goes for tibbles. That was him, right?
How am I not surprised she did that.
Tibbles had it coming, regardless.
Wow, I was not expecting her to have pointy ears, a her horn, or even a tail again. Still, kinda makes me want to see fan art of it.
You and me both.
Not sure if I should feel nervous or excited knowing hunter appeared sooner than I thought.
Princess Celestia*
12113513
Thanks for pointing out those typos; somehow they escaped my notice despite the several passes made.
ISS stands for In-school suspension. It was a phrase that never applied to me, thankfully, but I'd heard it a few times during High School.
Nope on the Tibbles thing; just some random orc.
Believe it or not, but that wasn't Hunter. It was just a random coven scout squad she went and traumatised. Hopefully not Steve though. Steve's a bro.
As far as art goes, I've half a mind to hack together a vector trace to show off my vision. The last one I threw together for a meme in a discord (Amity Blight Rimuru Tempest cosplay) turned out alright.
That confirms my question if Eda is in this story or not.
Wait, how does Sunset have a coven sigil already!?
I wish I remembered what the name was of her palisman is as it's name has been revealed, I just can't remember.
Lilith is gonna have quite the reaction once she learns Sunset doesn't know or who Eda is.
Damn...
I'm sure Lilith will believe you Sunset... in time, seeing she's still with the emperors coven.
Gulp.
Belos, more like baglos.
I'm afraid that ain't the same in the boiling isles after belos took over.
Crap.
12113521
Gotcha. P.s., o hope you don't mind the two long comments as I often like to react my thoughts to certain scenes from stories I read here, and since I'm quite a big TOH fan. Which is obvious seeing Luz is in my profile pic.
12113530
... she doesn't have a coven sigil.
As for Lilith's palisman, I don't think there was ever a canon name. There's some joke ones in the fandom, but I'm rather fond of Corvanc, which is from the Angel of the Owl House.
12113536
Crap, I must've misread that.
Not sure what I think about this premise for a story. Sure, the writing is on point, everything is well written and fleshed out, but this is making me think about why I liked The Owl House so much to begin with. For me, the key component that made Luz's journey so compelling was her mundanity. The fact that she was, and stayed, a normal human girl is what forced her to adapt, and improvise creative solutions to problems. But now, she's got this ultra strong spellcaster with her who could solve these problems for her, and this becomes less about Luz, and more about Sunset, and the stronger Sunset is, the less compelling the story becomes if it keeps to the tracks of TOH's main plotline.
12113677
It certainly isn't good for Luz's character growth if Sunset 'fixes everything' for her. Despite wanting to look out for her, it's a conclusion that it won't take Sunset too many more chapters to reach herself. Besides, she can't just be at the kid's side 24/7 and she does plan on trying to get home; getting Luz dependent on her power would be setting her up for failure, and possibly dooming the Boiling Isles itself. Instead, she'll be more likely to advocate for Luz' training to start a bit sooner, and possibly provide her with a few more tools to survive.
An Equestria Girl x Owl House Crossover story!?
Sign me up! 
Poor Sunset. Even though she has wronged others in the past, she doesn't deserve all the abuse from others. I hope that the students who bullied her and sent her to the demon realm are punished for their actions.
And most importantly, I hope Sunset will see her friends again. 
That being said, it's cool to see Sunset in the demon realm and I'm already hooked on this story! I'm looking forward in finding out what happens next, especially when she eventually meets Luz and the others.
Keep up the good work!
Now that was a fun chapter!
Sunset finally meets the Bad Girl Coven and she is now staying at the Owl House. I can't wait to see what happens next with Sunset!
Amazing crossover so far, can't wait to see where this goes.
Excited to see how Sunset would react to and interact with the likes of Amity and Hunter, given they do fall under a similar story of being troubled teens that go through a redemption arc later like her, plus all three being on LGBT (Sunset's bi, Amity's lesbian, and Hunter's bi).
So, will we get to see scenes of how the Humane 5 and Principal Celestia are doing in the human world and how they're reacting to Sunset's disappearence?
Same for if Sunset will try to use her magic book to contact Pony Twilight or Princess Celestia for help?
So for Sunset's form in the Demon Realm, does this mean her form there is mostly similar to her human form, with the main difference just being the unicorn horn and tail from her pony form? Is there a reason why Sunset has a different form in Demon Realm but not Luz?
And if the Humane 5 went to Demon Realm, would they be in a similar boat to Sunset of having their human forms in a hybrid with pony features with all five having their pony tails, Rainbow Dash and Fluttershy having wings, and Rarity having a horn like Sunset?
12113849
In my head, at least, Sunset's transformation was triggered by the lingering transformation enchantment from the original portal that was smashed, whereas Luz merely entered the Boiling Isles through the portal door in Eda's possession, which really doesn't seem to care what you are or where you come from. Her skin is a little less orange, but you're otherwise right on the money, her having a horn and a pony's tail, with the pointed ears of a witch. As for the Humane 5, it would all depend on whether they get their hands on a portal akin to the mirror, or more like Eda's door.
There will be 'meanwhile in Equestria/the Human Realm tied to Equestria' sorts of asides in upcoming chapters.
Belos did nothing wrong
I am already really liking what has been written so far. I really like the premise of an owl house - EQG crossover. The possibilities for this are myriad and all enticing.
If this happened irl, being behind bars is the last place someone like her should be.
I'd feel the same if I was in Sunset's shoes.
Though I think it's obvious they took her backpack and all it's content with them.
I guess I shouldn't be surprised on that last part.
Just go with it.
Even two years after I got into toh (I got into the show just a month after for the future came out) I still find that line on Luz saying weak nerd arms downright hilarious!!!
Luz can be a lot more different than you might know it Sunset.
You wouldn't want to wear the crown Sunset wore King.
That or Eda didn't want to see Lilith.
Weird how didn't just out it on her back.
That makes two of us.
Damn!
riding on Eda's owl staff.*
I think it's supposed to say sweeten the plot.
I hope Eda tells Luz that Sunset is sleeping in the basement seeing she doesn't find out the owl house has one til season 2 when she confesses her feelings to Amity.
I sure can't wait for th next chapter. I'll be waiting!!!
But the only question I have so far is the tag on twilight added to the story. But the only question I have so far is the tag on Twilight added to the story.

Since when were you a fan of owl House? I've seen your posts and you've talked about it maybe once in one of your stories?
You seriously better not let this brilliant thing die! This is absolutely amazing! Also a suggestion for a job for Sunset which would allow her to stay close to Luz. Have her get a job at Hex Side.
12114334
*riding atop Eda's owl staff, actually
As for the Twilight tag, it's because she's going to be the one she's most regularly in touch with Sunny and will be getting her own interlude scenes the most. While we get to see the CHS 5 + Principal C interact with some nuisances in Chapter 4/Episode 3, they don't play too big a role until 'Season 2'.
Any plans on making her continue the study of magic, including "the forbidden" magic?
Heh, she may be alone, but the silver lining is, she is the most harmonious pony on the isles. Heck, she basically is the Harmony's representative there :v
12114336
I've been the fan of the show since the first episode aired. And I referenced the show a couple of times in my stories.
