Age of Darkness

Deep in Canterlot Castle, in the ballroom to be precise, Nightmare stood with a raised eyebrow, starring in complete shock at the smaller pink mare in front of her. Nightmare had heard of Pinkie Pie through Zorak, though he told her of the alternate timeline in which she was defeated.
The mare in front of her looked nothing like what Zorak had described. Nightmare figured she was going to meet the bouncy bubbly mare Zorak had told her about, but she didn't. The mare before her was not bright, cheery, and bubbly. In fact, she was dark, seemingly depressed, and very much monotonous. Her mane and tail were not fluffy as Nightmare had expected, instead they laid flat and nicely brushed. Her coloration was also darker than she'd expected, heck even her cutie mark was slightly different.

The balloon's on her flank were not blue and yellow, instead they were black and white. This was not the same mare Zorak had described to her, but she still smiled at the smaller pony, and did her best to seem friendly. She also had no idea that Pinkie was Rarity's time, but she decided not to question it.

Pinkie bowed low to Nightmare "Hello your majesty, I am Pinkamena Diane Pie, but please just call me Pinkie."

Gosh, even her voice sounded completely opposite from what Nightmare had expected.

"Rise Pinkie, and please just call me Nightmare, I believe you've earned the right," said Nightmare with a smile.

"H-how would I have earned the right," asked Pinkie with a nervous blush.

"You have been placed in charge of planning one of the most important moment's in my life, you have a lot of responsibility resting on your shoulders my little pony. This party could very well make or break my relationship with my beloved," said Nightmare with a serious tone.

Pinkie straightened her pose and gave a confident nod "I won't let you down Nightmare."

"I would hope so, because if you did... I'd have you hog-tied, put in a brazen bull, only to be dragged out before you die, just to be tortured even more," said Nightmare with a happy face and cheerful tone.

Pinkie was completely speechless.

"No one would be able to find your body, that I promise," said Nightmare maintaining her happy face and cheerful tone.

Pinkie swallowed hard "I'll make sure no loose ends are left undone."

"Good," said Nightmare happily before walking away "I hope for your sake that is true, pregnant mare's can be awfully vengeful."

Pinkie was left standing in the large room, quaking in absolute fear, wondering what she'd gotten herself into. Rarity was standing across the room, hoping from the bottom of her heart that her marefriend wasn't going to be tortured and killed.

"Please Faust, in all your wisdom, grace, and mercy, let this end off without a hitch," mumbled Rarity worriedly.

A few hours had passed since Nightmare's little... warning, and everything was running smoothly. The party decorations were spot on, Zorak was distracted, and Nightmare's nerves were slowly calming down, nothing could possibly go wrong.... RIGHT!?

Of course, what did you expect to happen, this is a love story between a dark goddess and her dark best friend.

Zorak slowly entered the ballroom, he wondered why Nightmare had asked him to meet her here, he also wondered why the lights were off. In a flash the lights were thrown on and a group of ponies sprung out and yelled surprise.

"You're going to be a dad," exclaimed Rarity.

"Eh... what," asked Zorak with a confusion laced tone.

Everyone in the room fell deathly silent.

"You're going to be a dad," said Nightmare slowly and nervously.

"You... you're pregnant," asked Zorak in disbelief.

"Yes," said Nightmare gripping her stomach lightly and giving it soft prods.

Before Nightmare could even blink, Zorak dashed across the room, threw his arms around her, and began hugging her firmly, a happy smile plastered on his face.

"Y-you're not upset," asked Nightmare warily.

"Upset? How could I possibly be upset, I'm going to be a dad, I'm to happy to be even remotely upset," said Zorak happily.

Happy tears began staining Nightmare's cheeks as she threw her forelegs around Zorak and gave him a spine-breaking hug. Nightmare nuzzled Zorak fiercely, she was so unbelievably happy and nuzzling him was the only thing she could think to do. She hadn't expected this to happen so smoothly, why had things happened so smoothly. Things don't ever go this smoothly. Nightmare didn't care though, things were finally going her way, and she was happy.

"I love you Zory, so very very much," said Nightmare burying her muzzle into his neck.

"I love you to Nighty," said Zorak happily.

Everyone in the room audibly 'd'awww'd.'

"See Nightmare darling, as stated before, all you needed to do was tell him," said Rarity pulling her pink marefriend closer into her side.

Pinkie looked up at Rarity and smiled "love you Rare-bear."

"Love you too Pinkie-winkie," said Rarity nuzzling the smaller pink mare.

"We should probably start using condoms Nighty," said Zorak with a chuckle "we may be royalty, but I'm pretty sure we can only handle so much."

"I was thinking the same thing," said Nightmare finally letting go of her lover.

"Did anypony hear about what happened to Chrissy," asked Rarity out of the blue.

"No, what happened," asked Zorak.

"She finally found herself a stallion, one that she actually acquired legitly," replied Rarity chuckling lightly.

"I thought you and her were together," said Zorak with a raised brow.

"Oh goodness no Zorak darling, what you witnessed between me and Chrissy was nothing more than a mutually beneficial interaction," replied Rarity with a smile.

"So who's the unlucky stallion," questioned Nightmare with a smirk.

"I do believe his name is Flash Sentry, he's a day guard if I'm correct," answered Rarity.

"May Faust have mercy on his soul," said Pinkie lowering her head "she's going to suck him dry, and them suck him some more."

Everyone in the room laughed at Pinkie's comment, and silently offered up prayers of their own for the poor stallion.

Zorak was ecstatic, while he was a little spooked by how fast everything was going, he was happy that he was going to be a dad.
