I would read this fanfic.

@Solitair  
probably.

@reterusu  
Trollestia, perhaps?

@Giant_Neckbeard  
I refuse to beleiv that tierk didn’t plan that.  
also, Celestia is ooc.

@Giant_Neckbeard  
You are the best.

@Giant_Neckbeard  
Ha. A fate worse than death. XD

Twilight isn’t freaking out about having absorbed the other three princesses and having them rattling around in her head.
 
She’s freaking out about Cadence keeping the other two entertained by telling them about what she and Shining got up to on their honeymoon.
 
||*“Oh, but Twilight, since you now are me, you and Shining are technically married …”*
 
“Remember, Twilight, thou must ensure that we play at least five hours of video games each day! And practice thine Canterlot Voice regularly! Allow me to demonstrate!”
 
“Just think on the bright side, my faithful student. I’ll be able to stay with you forever. Evaluating your every move, knowing your every thought. It’ll be a test that will never end.”  
||  
“TIREK! WHERE ARE YOU? YOU CAN HAVE THE MAGIC, YOU CAN HAVE ALL THE ALICORN MAGIC! TIREK? TIREK!”
 
And in the distance, a scrawny Tirek is fleeing into the distance shouting “Nope nope nope nope nope.” at the top of his lungs.

“The curtains open. The audience anticipates. Thought when the curtains are unveiled they see no sign of singer, dancer, magician nor comedian. All they see is a plain old mirror. It took them a while to realize, the audience are the performers.”

tvtropes warning.  
not it yet, but some things are coming around

@reterusu  
Ever think that the writers, animators, and producers get a few ideas from us?

@Albus Fahrenheits  
I used to wonder about what fusion could be,  
then the show writers shared its magic with me!  
my little prophet, my little prophet!

@Solitair  
My Little Prophet

@reterusu  
I know! I had no idea when I commissioned this.

Just a reminder that this happened to an effect in the s4 finallie.

But they don’t account that they’re beings of pure magical energy, so if they transfer all of their magical energy to Twilight… They transfer yourselves.

There’s also the yellow stripes in the mane and tail, which isn’t a color in normal Celestia’s hair, as well as the shape of this hairstyle being a halfway point between Twilight’s and Cadance’s. But yeah, I did have a bit of trouble deciding how to incorporate Cadance into the design. Heck, I was originally going to try and put the rest of the mane six in as well, but I couldn’t make it work.

The only sign of Cadance being in there are the teeny hearts on her cutiemark. Guess her design is already a kind of Twilight-Celestia fusion.
 
Also this is awesome. The power of day and night and love and books. The ultimate Alicorn!

There can be only one!

All hail Princess Stardust!

 
Oh my god

@PonyPon  
“BUCK YOU!  
Now now twi,  
WE ARE NOT PLEASED!  
Well, this is going to fuck up our marage”

@reterusu  
“Whelp, I’ll let you work that clusterbuck out with yourself. Tooddles!”

@PonyPon  
“ I can’t! One quarter of me wants to panic, another wants to stay calm, another wants to yell, and the final one wants to bang my brother! “

@reterusu  
“I’ve been trying to take these things in greater stride. You should probably do the same, CeLunTwiDance.”
