Until an incident occurred, which resulted in Princess Luna sacrificing herself to save the day against a very powerful villain. While she’s technically still alive (and trapped again in the moon), Twilight couldn’t figure out a way to free her. This happened when Midnight was young, I’d say around…Teen Applejack aged.

This also resulted in Twilight reverting back to her more…anxious tendencies, out of a growing fear she can’t protect the people closest to her. Paired with the fact her friends aren’t readily available (and Spike can only do so much), she becomes overprotective of Midnight. This leads to tension growing between Twilight and Midnight,

Which doubles once Luster Dawn, after Twilight drops the “hey I want you to rule someday” bomb, vanishes. Like, no one can find her at all. Which means all that responsibility on raising the sun and moon falls onto Midnight. Over the years, their relationship worsens while they both (not) deal with the grief of losing Luna.

Midnight’s story would start when she’s younger than S1 Twilight’s age (let’s say in her late teens), and acting similarly to how she did. She keeps to herself, venturing Canterlot on her own (with guards trailing behind her) to read books about distant lands and other cultures. She desperately wants to experience more, but is heavily restricted.

As a way for her to venture out (in her safely made bubble), Twilight decides to send her to Ponyville so she can make friends on her own. She stays with Starlight, who’s now married to Trixie and has a daughter named Morningstar, an ambitious unicorn who favors her parent’s days of villainy versus who they are now.

They get along fairly well, and she meets more of Morningstar’s friends:

August Breeze, the hippie daughter of Fluttershy and Treehugger. She frequently helps her moms with their animal shelter, and can be seen swimming during her free time!

Golden Harmony, the daughter of Applejack and Rara. She is an upcoming singer who’s traveled Equestria, and can be seen anywhere sans Sweet Apple Acres.

And Petra Pearl Pie, the daughter of Rarity and Maude Pie. She makes jewelry and sells them in town! Has a bit of a standoffish rich girl vibe to her, but she’s a genuinely nice person.

The girls decide to have a sleepover at Twilight’s old castle (where Starlight and Trixie live in now). Midnight complains about not experiencing anything new and, to her surprise, the rest of the girls have the same complaint. They’ve either explored Equestria and have gotten bored of what they’re doing (Golden), or also yearn for new experiences (Petra, Misty, and Morningstar).

Offhandedly, Midnight mentions Twilight’s experience in another world, not even on Equestria’s map. Morningstar backs her claim and leads the girls to the portal, where they egg each other onto going in (once Morningstar is able to activate it).

The girls do end up going in….and ending up in the Equestria Girl Land! human world! After freaking out, Midnight comes up with the idea to stay for….awhile. For reasons that can be understood with her backstory. The girls agree to stay for at least a week or two, and decide to experience the most “fun” thing in a teenager’s life: Highschool!
