Diablo Crossover.

The Archangel of Justice destroyed the Worldstone to spare Humanity the corruption Baal infected it with. The force of its death knell shatters Mount Arreat and sends Tyrael hurtling across the endless planes of reality. He falls upon a world untouched by Angel or Demon, far from the sight of the High Heavens. So far, in fact, that he fears he will not be reborn from the Crystal Arch.

Wounded and near death, hope appears in the form of two strange creatures bearing the power of night and day.

Tyrael now faces a time of recovery as his power slowly heals within a body fashioned for him by his saviours. Justice Incarnate tastes for the first time the life of a mortal, and it is a strange, confusing experience .He has been left in the care of one Twilight Sparkle to learn of this world.

After all, where better to find peace and harmony than Ponyville?

The Cutie Mark Crusaders are all grown up but Scootaloo still doesn't have a cutie mark and still can't fly. For the time being she is living with Sweetie Belle and bringing home the bits by competing in the Equestrian Freestyle Motocross Tour. Things get complicated when Sweetie Belle reveals her romantic interests in Scootaloo. On top of this, Scootaloo is becoming more obsessed with the sensation of falling. As the pair searches for the answers behind Scoot's borderline-suicidal tendencies, they begin to uncover secrets that threaten the well-being of all of Equestria!

This story is a sequel to Twilight's Dollhouse

What do these ponies have in common?
Well, they all happened to be in the same room when THIS happened.

Each night I’m trapped in the dark, immobilized. I hear whispers as they operate on me: they say I shouldn’t be alive. Twilight refuses to tell me about the operation. Sometimes she can’t look me in the eye. What did they do to me?

Nothing used to scare me: I kicked a dragon in the nose, defeated gods of chaos and hatred, and control the weather. Now I feel broken. My memories have shattered, I feel wrong, and I’m afraid to tell anypony how scared I am.

I can’t even do the rainboom anymore. Who am I? I’m no longer the best flyer in Equestria, yet everypony assures me I am. Why won’t they tell me the truth?

The newly coronated Princess Twilight suffers an abrupt tragedy. Having lost two loved ones, she begins to question her own mortality, and that of her friends.

AJ, Dash, Rarity, Pinkie, Fluttershy. . . they are just the beginning. Twilight will live for thousands of years, so every pony she cares about—every pony she will ever care about, will die.

She could barely handle the pain of one funeral, let alone the thought of hundreds of them. Twilight finds a clever way to ensure all of her friends never die. They can’t all be ageless alicorns, but they can all move into Twilight’s Dollhouse. Then they can be best friends forever.

I don’t question the “life” bar floating over my head, or my “EXP” gauge, or the little phantasmal boxes that appear whenever I look at an “equippable” object that show its “statistics.” It’s normal for small messages to appear in the sky every now and then, such as [System update in 2 hours.] My kind worships the Developers, higher beings that direct, create, and control everything we see. It’s all normal. This is how things have always been, since I was born. My father, my grandfather, my ancestors have all accepted and coped with these elements.

So why does everything feel so... fake?

My name is Twilight_Sparkle, and I know there’s something wrong here.

Willing to risk an early grave for a shot at immortally, Shining embarks on dangerous quest that set's a chain of events into motion that could very well mean the end of both harmony and chaos.

A year after his defeat by the Mane Six, Discord finds himself able to use a bit of chaos energy. However, he isn't able to free himself, so he decides to get revenge on the ponies who trapped him. This is the story of how the girls deal with Discord's revenge scheme, which also means adjusting to something none of them ever expected having to deal with: truly single motherhood.

During a picnic, a mysterious portal appears out of nowhere in plain view of Twilight and the rest of the gang. Curiosity gets the better of them, so they decide to enter the gateway to another world and see what's on the other side.

After transporting them to this strange new world, the portal powers down inexplicably, trapping the Bearers of Harmony in a strange cube land with no way back.

How will they get home? What dangers will they face lurking around every corner?

More importantly, what does a lonely crafter have to say about all of this?

A re-imagining of my old story, with heavily edited chapters.
