This story is a sequel to Tantabus, Mk. II

The new and improved Tantabus has behaved itself thus far, but Luna has delayed telling Celestia about it. Until one night when it jumps into Celestia's dreams to say hi and inadvertently reveals itself. Luna must now introduce Celestia to her little bundle of self-aware psychic dream energy sooner than she imagined.

Trying to patrol the dreams of every pony in Equestria can be stressful. To ease her burden, Luna retools the Tantabus to turn nightmares into good dreams instead of vice versa. Aware of her mistakes from last time, she tests it out thoroughly, making sure there are no unexpected behaviors. And as far as she can tell, there are none.

Except that it's started calling her "Mom".

Faced with the prospect of possibly creating life, Luna seeks out Twilight's advice and assistance. With a little luck, they can get this all sorted out before the sun rises.

Tirek has won, and Twilight's friends are gone. She and the other princesses have just one chance left. Maybe if one of them can go back, she can warn them right when he escapes and stop this all from happening.

It might be a long shot, but it's the only chance they have left.

MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

OH MY BUCKING GOD! LOOK AT THAT BEEEAAAAUUUTIFUL COVER ART MADE BY enamis. I couldn't thank you enough for making such a fabulous cover art I can't believe I was your inspiration (I felt so important) but that doesn't mean I left nightglimmer22 for trash, ooohhhh-nnnooooo, here's her cover art as well [img]http://s29.postimg.org/60p4zg793/image.jpg[/img]
I cannot thank you people enough you fill me with Determination!

Wishing she rather be in a prison of stone herself, Celestia grieves hourly about how her life as gone amiss. One Luna that casually pranks her is enough as is, but triple the matter and you have a bride for any Draconequus. Dealing with both the silliness of Luna's youth and present, the Goddess is distracted to Nightmare's plot to overthrow her. As fast as her faithful student can work, Twilight Sparkle is in search for a way to reverse the spell, the only question is: can Celestia hold out long enough?
A/N: In all fairness, I had this thing sitting in my box for a while now. Any criticism? I need work on sentence structure and flow, if you don't mind pointing it out. The emotions and characters would be nice as well!

Twilight Sparkle awakens one morning to find all of Ponyville wholly consumed by a spreading cloud of white.

Hopefully The Stranger inside her castle can help her understand what this all means.

This story is a sequel to Triggered

Sunburst might be a grown stallion, but that doesn't keep an overprotective sister like Sunset Shimmer from smacking a filly.
