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.

Some Canterlot entertainers aren't just musicians... and some ponies fall in love with them anyways.

When one of Equestria's most popular cellists appears at Twilight's birthday party, it's just another gig for Octavia, but a shock for Twilight and the rest of the party-goers. She arrives, wishes Twilight a happy birthday, wows them with her beautiful music, wows them with her musical beauty, and doesn't leave until after everypony else has left. So when a few ponies suggest that this 'entertainer' might be more than just a musician... some eyebrows are raised, but nothing more. Twilight is beyond reproach, after all, and Octavia can earn her living however she wants. When she sticks around Ponyville, however, it becomes a slightly different story - Twilight is romantically-naive, after all, and Octavia is... most certainly not.

The romance of Twilight Sparkle, Celestia's protege, and Octavia van Clef, Canterlot's most famous entertainer.

Rated 'Teen'. Per FimFiction's rating guidelines, this story contains some 'more adult themes', but has no 'graphically adult content'. Rated primarily for sexually suggestive material, but also (in later chapters) alcohol use and adult language.

A flip of a coin. A twist of fate.

Twilight Sparkle, younger sister of Princess Celestia's personal student, Shining Armor, grew up listening to her brother's bygone dreams of joining the elite of the elite: The Royal Guard.

Now, fresh out of the Academy, this young mare is ready to prove herself equal to the deeds of the great soldiers she read about as a filly. Too bad the princess she ends up protecting isn't Celestia.

Princess Celestia always knew that Twilight Sparkle was destined for great things, but she never revealed the source of that knowledge, not even to those closest to her. When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

There may be spoilers in the comments. You've been warned.

For their first home together, Twilight and Applejack wanted a house close to Applejack's farm and big enough for Twilight's books, with a little something special besides. They settled on the perfect place, one of the oldest barns on Sweet Apple Acres, and had it converted into a comfortable house for their little family. But when strange things start happening just after they move in, Twilight finds that she has a mystery to solve before she can really call her dream house "home."
