Celestia has a dangerous creature held in the deepest of Canterlot's high-security dungeons. It can create ponies (with full backgrounds and histories) with it's strange and often-times prophetic powers. The Princess does her best to keep it under wraps, but its only a matter of time before it's "creativity" will get out of control.

Every night when Pinkie Pie goes to bed, Pinkamina rises. Using the cryptic powers of the Pinkie Sense, she deciphers the clues and goes out to prevent the deaths of others. Meanwhile, the Stallion Lickity Split is developing feelings for Pinkie's darker half, and the Royal Sisters do NOT like Pinkamina messing with fate.

This story is a sequel to A Certain Urge

Pinkamena has taken control of Pinkie's body. Its easy to say that she has done some heinous and horrific acts with that control. If Pinkie doesn't get control of her body soon, she'll fade away and Pinkamena will be in control of every aspect of her life. She needs to fight. Will she be able to regain control, or will she fade away while Pinkamena does anything and everything she wants to her life?

EDIT: Currently re-editing the chapters. So if you read through one and the next is different, that is why. Should be finished in a week or so.

"A stalker's life was full of adrenaline and wonders, of loneliness and misery, of death and horror, mixed together in the maelstrom of madness that is the Zone."

A S.T.A.L.K.E.R crossover. Hiker, an experienced wanderer, stalker and trailblazer find's his way into the center of the Red Forest, unreachable ever since the Clear Sky faction was annihilated at the nuclear power plant and Strelok was sent back into the Zone. In it's dark reaches, he is contacted by the Forester, and through a twist of fate, ends up in the antithesis of the Zone, a land of magic and happiness. Yet not everyone wants a sedate, safe, contented life in Equestria...

For all those who have never played/understood the STALKER series: http://stalker.wikia.com/wiki/Main_Page
All the locations, anomalies etc in capitals will be on there.

Pinkie Pie is being tormented by horrific nightmares. Unable to deal with it by herself anymore she seeks out Twilight's help, but will it have been the best decision when she finds herself alone in an abandoned, fog filled Ponyville?

There have been a LOT of high-quality readings of Silent Ponyville, but this one is my personal favorite:

Pinkie doesn't tell ponies about Pinkamena and Surprise. The doctors said that they were bad for her, that they were a disease, but she disagrees. Sure, Pinkamena's a bit of a grumpy-pants, but she's still a great friend! She's often the voice of reason to counter-act some of the other two's crazier ideas, after all. Surprise, on the other hand, is a great prank-player, and always up for some fun. She's more like Pinkie, only more hyper. Both are great fun to be around, and they get on well.

Thing is, she knows that if she told ponies about them, then they would be dragged back to the hospital. And then be 'treated' again. None of them want that. Because of this, not even her best not-in-head friends know about them. The three of them have, for years now, been careful enough to keep the existence of Pinkamena and Surprise secret.

This has, of course, gone out the window now that Twilight is hammering on the door after overhearing one third of a conversation, with no sign of anyone else talking.

Hints of F/F shipping inside. Nothing will actually come of it here, though. Maybe in a future story.
