This story is a sequel to Headhunters

The headhunters came, saved the day, and then they left. But in their wake they not only left a pile of Covenant bodies – they left Princess Twilight Sparkle with a spark of wonder. An interest in the galaxy that surrounded her little home planet; an interest in the lurking dangers and the magnificent wonders of the universe.

Unfortunately it seems some of the danger and wonder is coming to visit Equis. So it’s time for the bookish shut in to throw herself into the galaxy to find the warriors who would help her defend her home.

This story is a sequel to The Mare of the Night

It's been six months since Starlight Nightflier, batpony prostitute, was hired to be the conversation partner of UN ambassador Daniel Habbuck. Since then, she's gained a new job, a new home, and a new future for her beloved son.

But that's not enough for Starlight. She wants to be more than just a friend to Daniel. Much more. But something's holding her back. Something from her past that refuses to die...

Daniel Habbuck, UN ambassador to Equestria, hates his job.

Sure it pays well, but it's hardly worth having to put up with flank-kissing politicians and the stomach twisting anxiety of knowing that he represents all of humanity.
One night, after a particularly tense meeting leaves him wound up, Daniel is desperate for somepony to talk to. With his friends either busy or too far away, he hires a batpony prostitute, just so he can have some company.

As he soon learns, there's much more to this streetwalker than meets the eye...

Rated T for sexual references, but no clop.

This story is a sequel to Voyage's End

Eleven years has passed since ponies and humans met for the first time. Now, Twilight ventures out on her most incredible endeavor to date.

"Once more, we boldly go into that great unknown." -Twilight Sparkle

Her death had been catastrophic. Deadened iron in her core, sapping her strength, then the incomprehensibly painful collapse into her own body. But that was in the past, and Cygnus X-1 had grown content with her life as a black hole.

But then, she fell to a strange planet in a stranger body. Not knowing how to eat, drink, or communicate, Cygnus X-1 would have met her end if it were not for meeting an organic who took mercy on her. But now that she had returned to life, Cygnus X-1 found her embers sparking, and within her new powers is the way for her to return...

... and if anyone tried to stop her from going home? She was going to kill them.

She is the last. All her kin are gone. They'd either been blown apart by the Friendship spell so many ages ago or, in the case of her sister, changed their diet from hate to love. Cryoxia is the last of the windigos, but she is determined to be different, to never go back to those days ever again.

She'll make friendship from hate. She'll adopt an alicorn foal as her sister. She'll take physical form and learn how to move the celestial orbs with her mind. Celestial... has a nice ring to it. And she'll ally with the other nations in the world, establish friendship and preach harmony, no matter how they may diminish her food source. She'll make a world so wonderful that it will starve her to death.

Or die trying.

Now with an amazing YouTube reading by the equally amazing AShadowOfCygnus!

During its two year search for Shepard, the lone Geth traveled across the galaxy, exploring worlds both known and unknown. After a blind FTL jump to escape from an Alliance patrol, it found itself in a previously undiscovered system, a system without a mass relay and completely cut off from the rest of the galaxy. It touched down on one of the worlds, a garden-like planet, with the intention of gathering data on any flora and fauna that may have been present.

Instead, it made a remarkable discovery.

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?
