Codex Ex Equus

The writing account of Deus Ex Equus.



For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.


Sequel: Pony Courtship Rituals


Some beautiful fanart of the end of chapter three was done by Dmann892; you can see it here.

More awesome fanart, this time from chapter one.

Now with a TvTropes page (obligatory TvTropes warning goes here).

If you want a Russian translation, you can find it here.

There is now a reading of the story on Youtube, which starts here.

I never knew how much I needed this in my life until right at this moment. This is going to be wonderfully awkward and I can't wait.

I did notice a few minor typos here and there, but nothing major, so keep up the good work and I can't wait for chapter two.

Interesting start. Will this be leaning more into the romance or the comedy?

[,,,] she decided to try and move away, only to be effortlessly scooped back into place by a holed hood.

Small typo at the last word here.

Ok actually looking at that it can be possible, letter could be more double meaning because its hard to get that Twilight could read all this as sarcasm without thinking.

But yeah I can see this

Twilight...you need to get out more if that's what you got from that letter?


Changelings and alicorns have two hearts? Can they regenerate?

This is cute, hilarious and with plenty potential for crazy changeling romance shenanigans. I like it!



Changelings and alicorns have two hearts? Can they regenerate?

What do you think happened in Magical Mystery Cure? I mean, she glowed and everything. ;)

Nice fic, I will keep an eye on it, though I think it's pretty complete as is.



I believe this is also the Cardassian way of dating as well.

Will love to see where this goes! There was another ChrysaLight story that took this concept down the dark / gore path (stalking = romance, kidnap = dating, torture = affection), and it's nice to see someone carry it down the comedy/romance path instead. Keep it up!

Oh damn. I remember that, it was like a whole episodes worth of snippy comments in the build up to some mildly amusing punchline. And O'Brian getting a sore head.
Good times....

Hehe, I'm fairly amused. Let's see where you take this one. ^^

Oh man. This looks like it's going to be amazing.

You have my like, good sir.

Also, you really have me wondering what ka-klack means in Changling.

"Good morning, beloved," Chrysalis cooed, fondly nuzzling the top of Twilight's head.

"Umm, morning. I think," Twilight ventured, noticing the complete lack of daytime cues in the bowels of the hive.

"I'm so excited about our first day together! After breakfast let's take a tour of the lower caverns. The glow-worms are so lovely when they feed on-"

"Umm, Chrysalis?" Twilight interrupted.

"Yes, dear?"

"Why didn't we, umm...consummate our marriage last night? I mean, don't get me wrong! I'm not complaining! I'm just...curious."

Chrysalis gave Twilight a slightly confused look.

"Did you grow an ovipositor when you became an alicorn that I somehow didn't notice?"

"An ovi- NO! Of course not! Ponies don't lay eggs."

"Well, there's your answer. Now, about those glow-worms..."

THIS IS ALL THE COOKIES. Seriously, this my OTC, my One True Crackship and I'm so excited to see it get played out in something other than dark and creepy.

hearts, actually, she has two like an alicorn,

my first thought was that ponies were larval Time Lords.

Typo time:

only to be effortlessly scooped back into place by a holed hood.

holed 'hoof'

Chrysalis made her way through the tunnels, walk smoothly, hardly jostling Twilight at all.

'walking', not walk

On the other hoof... from everything Chrysalis had known, she had been in a fully reciprocated an completely normal

'and' completely normal

Anyway, this is glorious. Please, by all means, continue.

So basically.... Klingon courtship.


...This is now One True Crackship. Please continue.

Here's the sad part. It makes Canterlot Wedding's result make sense.

BUT, it's well written and the amount of hilarity that can come from this...I approve whole heartedly.

6629906 It's most likely the replacement drone's name.

Ya know, what I really have to wonder is how Chrysalis made this mistake. Unlike Twilight she can sense the emotions of others, she should have known that all Twilight was feeling was anger not lovey-dovey-flirtyness during their encounters.

Wanderer D

Loving it! Looking forward to the next chapter!

This chapter has definitely confirmed this ship as my "One True Crackship." Good show, my lad! You shall get all my likes, which is 1.

I am both intrigued and laughing like a moron. You have my upvote, and here's a moustache! :moustache:

I'll be tracking this one. :twilightsmile:

You have piqued my curiosity, I laughed, so now I favor so I may read more.

An instant like for the description alone.

This made me giggle, keep up the good work :twilightsmile:

And here I thought a lot of the anger, fights and sarcastic barbs come after the wedding.

Now I just have an image of Celestia looking honestly(?) perplexed at Twilight's confusion.

All this time, she thought that her student was going along with the courtship. She had a changeling partner herself a few centuries ago, after all. The whole back and forth was just so romantic she didn't want to step in and ruin things.

Luna is just impressed Twilight saw past the brutish exterior, but Twilight did redeem her after that whole eternal night thing, so..

6630198 They feed on love, why would their relationships be built on constantly draining their significant other. They probably go for the love/HATE relationships. (at least, that would be my theory based on this story's premise)

Yup, this is kinda new. :) I'm game! *tracked*

6630007 Needs more headbutting. :rainbowlaugh:

This is hilariously cute, I have no words... :pinkiehappy:

Hehehe. This had me chuckling throughout. But now I wanna know more. Let's see where this goes! *tracking*

Huh. This reminds me of Ranma 1/2.

Well one thing is certain. If its a ruse or genuine. If Twi and Chryssi stay together or not.

Rainbow Dash is never going to let Twilight live this down :rainbowlaugh:

Also Rarity is going to insist that even if Twilight and Chrysalis are married by changeling law they still will need a pony ceremony as well and she will have so many dresses to make :raritystarry:

I actually think it would be hilarious if everyone knew except Twilight. Can you imagine?

'What? Of course we knew, darling! The Princesses told us all about it! In fact, I've been busy making dresses ahead of time for the occasion.' 'Eeyup. Told us talkin' 'bout it was all taboo n' such.' '........WHAT?!'

into place by a holed hood.


I'd experience something so romantic until I met you.

Wow. Imagine the romance novels... or the teenage flirting.

I guess I would get banished to... friendship?

That would actually be kinda horrific, to be turned into energy and crammed into an emotion.

including a few books Twilight didn't even recognize that seemed to be changeling written–!

There's the quickest way to Purplesmart's heart!

This world always needs more Twysalis. Fav!

I find the pace a wee bit on the fast side, but can't wait for the next chapter :D!

She's going to have to explain this to her friends, family and mentor soon if not next chapter. Oh boy. I wonder how Cadence and Shining Armor are going to take this.

The description alone made me giggle and think, "Yeah, I can see that." This is beautiful and I accept this crackship. Let us continue!!!

6630346 Ah, but that's why Changeling marriages work so well!!:trollestia: They get see each other's worst long before they tie the knot. And to be honest it is truly beautiful when you see a changeling find that special one...the one who gives as good as they get. So sweet really.:raritystarry:

this is utterly ridiculous and silly.

Fav'd - Have a like.

She could try being an abusive wife, but if fighting equals dating to Changelings hitting them could be considered sex.
