In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Being the Princess of Equestria is busy work. Luna would know. She raises the sun and moon everyday, looks over the dreams of her beloved subjects, and, well, runs Equestria. Now, in addition to all that, she must find herself a protégé, before her sister's banishment ends!

But, that isn't the problem. The problem, is that three particular fillies stand out for the role!

Who will she choose? Can these three fillies become friends? Who will become Equestria's future savior!?

I guess you'll have to read to find out~!

First story of the Trio-verse.

Now has a sequel, One Year Later

After a vigorous day of organising and sending reports to Celestia, Twilight notices Spike is feeling a little ill. He slowly grows more and more cold, before finally falling into a coma that Twilight fears is her own fault.

Going to the Princesses for help, Twilight eventually is brought before an Elder Dragon and comes to the realisation that she may have failed as a caretaker, a friend and as an older sister.

*EDIT* Okay, okay. You guys win - I'll write an additional chapter or two. I've marked this story 'Incomplete' for now. Follow up chapter has been done. If you want more, let me know. I'm sure there are a few other characters I could write a chapter on (Except for the dragons, of course)

*DOUBLE EDIT* Okay, wow. I seriously didn't expect this to take off as well as it has. This is honestly probably one of the best days of my life. I'm so glad and happy that you've all enjoyed the story.

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....
