"Would you tell anypony if you knew the world was going to end, Twilight Sparkle?"

Twilight reads about a way to view a pony's soul, to see everything about them laid bare. When she tries it on her friends, will she be able to look at them the same way again? Or will the secrets hidden in their hearts drive her away?

(Yes, I borrowed the idea of a "soulgaze" from The Dresden Files, because it's something that really fascinates me. It's not a crossover, just an idea.)

Now has a sequel!

Moon's Favor is a short, tragic comedy involving three main parties - Anonymous the Human, Luna, and Celestia. As it stands, Anonymous is in Canterlot as guest to the Royal Sisters. There, he describes the many facets of humanity to the intrigued Alicorn audience. This story focuses on one particular day, where the subject of celestial spheres arises. As Celestia finds herself more and more pleased with Anonymous' tales, Luna becomes depressed. As Anonymous tries to convince her controlling the Moon is not all bad, he devises a surefire way to help Luna win the hearts of her people. Little does he know, the end result could have catastrophic consequences.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

One day Princess Celestia and Luna found new technology called “Portal Technology” allowing you to create two portals and enter into one and exit out the other. Using the smartest scientist from all over Equestria, they created a company called Celestial Science, after a few years Celestial Science was THE most popular science company ever, and after a few more years they created a computer called GLaDOS, GLaDOS was a creation of Celestial Science, a personality core designed exactly to be fitted as a central computer mainframe. The project began under the oversight of a stallion named Cave Johnson over the company, and was an attempt to create a fully functional, advanced artificial intelligence which was originally intended to be occupied by Johnson as one of his attempts to cheat death. After it became apparent to Johnson that he may die of moon rock poisoning before development on GLaDOS would be completed, Johnson motioned for the personality core to be based on his daughter Caroline instead.
After a decade's worth of hard work, GLaDOS was officially activated as part of one of the many events during the company's "Bring Your Daughter to Work" day. The scientist started enlisting ponies, pegasai, and unicorns of all kinds as test subjects for Portal Technology, Cave Johnson then enlisted a “special” test subject, a human, and yes, you guessed it, that “special” test subject was me. He enrolled me by using a special portal that was able to jump through universes, he just chose somewhere, reached out and grabbed me. But he didn’t just choose me, he also enlisted six other test subjects with me, to work on my cooperation. Six ponies, there names were, Twilight Sparkle, Rarity, Applejack, Rainbow Dash, Fluttershy, and Pinkie Pie. There a funny bunch, and they were tons of fun to test with, but one day that fun came to a nightmarish halt. One day GLaDOS found out that she was able to take control of half of the facility's features, and she deemed that the scientists were getting in the way of science.
So one day GLaDOS began killing most of its inhabitants by flooding the Enrichment Center with neurotoxin. However, only few if not only one of the staff such as Doug Rattmann had survived her attacks. I, Twilight, Applejack, Rarity, Rainbow Dash, Pinkie Pie, Fluttershy, Celestia, and Luna survived the attack. After the attack Celestia and Luna took it upon themselves to stop GLaDOS, we all wanted to help of course but they said that we needed to stay out of sight incase GLaDOS’s turrets came by, so they both put us in separate rooms that resembled hotel rooms and told us to take a nap there until they returned.

The plight of the endless CT-T war has arrived in Equestria! Observe the Equestrians as they watch the CTs and Ts duke it out and see endless humans die and come back to life, all while watching their beloved buildings and monuments be possibly destroyed every match for 10 rounds!

And a special Thank You goes to The Sentient Cloud for allowing me the honor of continuing this great story after he retired from writing fimfictions.

As it turns out, this story is eerily similar to Lyra Heartstrings and the Hand of Man. Due to their similarity, I feel that it would be appropriate to give said story a mention.

A crossover of Red Vs Blue - the Halo Machinima series - and My Little Pony: Friendship is Magic, primarily starring Epsilon, who is recaptured within the Epsilon Unit and finds himself in the land of Equestria. Will the resident ponies and him become best friends, or will the situation degrade into a flurry of insults?
Hedge your bets, folks.

Follow Jason as he attempts to cope with his immortality, not to mention waking up in a world run by ponies!
