Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Cause and effect. Opposite and equal reactions. If a butterfly... You know how it goes. The point is that your actions, large or small, have consequences. If they turn out good or bad is often not up to you. Especially when you live with the Princess.

But fear of the consequences is not a reason not to act when you need to.

This story is a sequel to Responsibilities

The 'adventures' of Blank Page continue. Changelings, Griffons and Princesses. At least he have learned his lesson not to volunteer for things anymore.

Yeah. Right.

That would involve him learning from his mistakes and that would be horrible. Celestia in particular finds it rather hilarious.

That's how you end up with Duties.

Even if nopony else did anything, he could get himself into plenty of trouble all on his own. 

So, while Equestria seems peaceful for now, that may change. Or at the very least, he'll manage to make his life interesting for himself.

Whether he likes it or not.
