Artemis

Queen Midnight Lullaby Deus Artemis Nightmare, Lune Invictus

she/her  - transgender mare - lesbian - fully ascended alicorn - 7,000+ years  old (calls herself 29 since that's how old she was when she ascended)

as  a person, artemis is the moon. she's very cold and grumpy and  introverted, preferring to keep to herself and her work. however, she's  actually very community minded. when she's in her element she's quietly  helping people build community and help each other. you know how if the  earth stopped rotating the moon would keep orbiting it until it got back  up to speed? that's what artemis is like. she doesn't care for the  spotlight and is happiest behind the fires of a forge. she's very  creative and has a lot of hobbies. very musically gifted. she's very  kind and gentle, especially since she is Huge Large. she has a heavy  boston-like accent.

artemis is technically  queen of equestria, along with her partner solaris (well, partner sort  of, she and solaris have... Things going on). however, after the  nightmare moon incident she was mostly cut off from her power thanks to  the elements of harmony being overprotective and she refused to live in  the castle's basement in retirement/as a dirty little secret. while  celestia is princess-regent she has been traveling around the planet as  an earth pony named midnight lullaby  (a translation of her name from  back when she was mortal). a couple years before the show she wound up  in ponyville thanks to solaris' magic Hunch. she wants to be there for  her daughter when she comes back. right now she's ponyville's primary  smith, creating both practical things and beautiful filligree jewelry.  she has a wonderful working relationship with rarity.

the  tl;dr on her backstory is that about 8 thousand years back an old  empire accidentally blew up the moon and had to put it back together  Weirdly and Badly. the machine used to raise the new moon and keep it in  orbit around the planet sapped the magic from the ponies forced into  using it. nigh a thousand years later and artemis was living as an earth  pony named midnight lullaby. she was her father's only child (she  believed she was a stallion at the time) had to live with the impending  burning of the lands thanks to solaris' rage. when the fires approached,  artemis was the only one to recognize that there was a person causing  the flames and approached the impending doom with kindness and a  lullaby. in gratitude solaris handed her the moon and she raised it,  becoming an alicorn in the process.

her  eventual relationship structure looks like a) her and solaris' Secret  Third Thing Millennia's Worth Of Do Not Separate Them marriage/divorce  thing b) her gf rarity and c) their joint gf spitfire

celestia  and luna were born ~1700 years ago :> artemis was pretty okay as a  parent but she's not immune to also having screwed up her kids

she doesn't have a cutie mark because as a fully ascended alicorn her whole body is her cutie mark! also i hate designing them.
