When the sky over the Crystal Empire is split open by a dark tear, Celestia, Cadance, Luna and Twilight must figure out a way to stop it. But in order to defeat darkness, sometimes you NEED darkness. And that leaves only one option; Sombra.

With his powers under lock down, and a growing connection to the strange darkness, can Sombra learn what it really takes to earn an empires respect, or will he abandon them to the darkness from another world?

After getting blasted by a wave of happiness, Sombra wakes up months later with a completely different personality and is forced to live with the memories of what he did and what he was. However, with a little patience, and a lot of help, maybe he can change that, and become something a bit better.

Fun Fact: This is the first story (and currently one of only three) on this website tagged with Redheart and Sombra.

Takes place in an alternate universe where Celestia and Luna used the Elements of Harmony to slay King Sombra.

Celestia and Luna are no more. The sun and moon have collided, and the heavens torn asunder in the aftermath of their final battle. The Elements of Harmony are missing, presumed forever lost. The fiends of Tartarus are on a rampage, and no one can stop them. And to make things perfect, the ruler of the nation of Boardor has decided to invade.
Desperate, Clover the Clever's last living student gathers together 108 virgin mares, in order to perform a ritual that will revive King Sombra. They succeed... kinda.
A human, in King Sombra's body, suddenly finds himself in an Equestria in a downward spiral with a bunch of technicolor ponies begging him to save them. Convinced that he's either dreaming, stoned, or insane, he tries to go along with it as best he can, although the voice in his head, a very angry voice with a hunger for conquest, crystals, slavery, and stairs, isn't doing much to instill confidence in his own sanity...

It's Sombra and Pinkie's 10th Hearts and Hooves Day, and while they want to celebrate, there's one issue...

Their son.

This takes place after the events of No Day But Today, though it's not really a sequel. This is a Hearts and Hooves Day special, really. Yeah, I know it's late, but whatever, I do what I want.

I never thought I'd get a family of my own, let alone the one I have now. Then, one day when I got home, everything changed as soon as I saw a red cloak and the little gray Unicorn in it.

"Pinkie."
"What?"
"I'm pregnant."
"..."
"Pinkie?"

Sombra decides to prank Pinkie, but, like the last time, it doesn't go very well.

Stories that follow the original are optional. This story takes place years after the first, so the setting is different.

This story is a sequel to Meeting The Family

Today is the day. After months of planning, prodding, and picking, the day of the wedding has finally arrived.

But, as the wedding is about to begin, there are tensions and stories in multiple areas, ranging from planning troubles, wardrobe malfunctions, lost rings, wedding dates, and relationship debacles.

In this tale, you will hear the tales of the bride, the groom, the wedding planner, the Mare of Honor, the guests, the flower fillies, and the Best Dragon and Best Draconequus, all as they prepare for the day in which a former tyrant and the Element of Laughter will join together in matrimony.

When Halloween rolls around and Pinkie gets into the holiday spirit, Sombra ends up having to get involved. That includes dressing up.

This idea was inspired by scoots2, and since she's brilliant and hilarious, you should totally check her out.

Fourth installment of the EG SombraPie series.

After Sombra gets into an intense argument with Pinkie, he seeks out advice from her friends, only to find they side with Pinkie on the matter.

The poor, damn fool.
