as far as lore goes i have to be a bit vague for now bc im still really just starting to workshop it, but a couple important things:

they are not related at all, in fact in this point in their lives they're hardly even close friends

radiant dawn is a unicorn who showed exceptional magical prowess even at a young age, still deciding if im making her from a family of unicorn nobles or not... but other than that she's actually very Nonserious and easygoing up until later events and her ascension

moonlight dream is a regular every day pony, born from an earth pony and pegasus, her colors are much duller than other pegasi. shes not as doom and gloom as she looks, she's just very tired

and heres a discord. he was just kinda mischievous and annoying before he went all chaos overlord and had to be imprisoned in stone

Sunny Daze (she/her)

The firstborn, and the only true alicorn of the three, she's next in line to take over Celestia's duties and roles (twilight is doing other stuff in my au, will talk abt that sometime)

Appears to be the perfect pretty happy princess all the time, how does she do it??

She's the most collected and responsible, and is usually the one to deal with any political or social events

Cloudy (she/her)

Secondborn

While she appears to be an alicorn, she's more like a unicorn/draconequus hybrid, her wings are different than that of other alicorns or pegasi upon closer inspection. She uses magic to disguise herself as a regular alicorn to try to appease ponies

Feels stuck in her sister's shadow, wishes she could keep it together as well as her, she also has middle child syndrome (celestia unfortunately has to spend a lot of her time with sunny when shes not already busy)

Prone to magical outbursts when she gets emotional, which she is working on, but its difficult when you're so full of potent pony magic on top of chaos magic

shes not really considered for taking on any particular royal or magical duties at the moment, much to her chagrin

Vex (they/he/she)

Thirdborn

Takes the most after Discord both in appearance and personality

They don't care what anypony thinks of them, unafraid to be 100% themselves (unfortunately for everyone but pinkie pie, this includes the occasional chocolate milk storm)

Full of mischief, but not malice

Vinyl Scratch

I see vinyl as nonbinary, always have, they go by any/all pronouns. i like to imagine she carries a lot of "traditional" unicorn traits such as the pure white coat, and fetlocks (though he cuts them for convenience). I did also consider giving her the long iconic unicorn tail, but I felt it clashed too much with them. they dye their mane and tail, most you'll see of their natural color is the roots occasionally poking out between touch-ups.

i dont have any strong opinions or headcanons regarding their silence in the show, I think they're just too absorbed in their tunes to talk when they're out and about lol

Octavia Melody

I honestly don't have a lot to say about her right now, I just wanted to give her a bit more visual appeal. I do like to headcanon her as ace though!
