Commander James Bond was one of MI6's top operatives. Having succeeded in countless missions and bringing down international terrorists such as Le Chiffre and Dominic Greene, Bond is sent to Istanbul to retrieve a hard drive containing the names of every agent involved in undercover affairs. The hard drive in question has fallen into enemy hands, and it's his job to get it back.

After disastrous events in Istanbul during the mission, James finds himself in an unfamiliar land, and soon becomes entangled in a tale of international espionage.

Only one man can protect Equestria and its princesses in this new time of crisis, and his name's Bond.

James Bond.

A sequel has been published: An Equestrian Princess in London.

Twilight embarks on a journey to Skyrim, feeling unnaturally drawn to the foriegn province. She expects only snow-covered ruins, but more awaits her there than she would have ever imagined.

Every hundred years, Luna departs from Canterlot to launch an inspection of the mighty prison complex known as Tartarus. This time, though, the new Chief Warden has something different in mind: he thinks it's high time somebody inspects the way Luna runs things.

She's got a feeling it's going to be a long week.

Thanks a ton to Silverguard for the awesome cover!

A long time ago, in a galaxy far, far away...

The Republic is dead, and from the ashes the evil Galactic Empire has risen, with the malevolent Emperor Palpatine at its throne. Across the galaxy, Lord Darth Vader hunts down the last of the Jedi, aided by the ruthlessy efficient Stormtroopers of the 501st Legion and the Star Destroyers of the dreaded Death Squadron.

The Conclave on Kessel has failed, and the Jedi have been slain. However, Darth Vader senses something deep within the abandoned mines...

"I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man."
-Thomas Jefferson

Three hundred years ago, Equestria tried to assimilate Earth.
They failed. They fled, rather than face justice.
We moved on. We conquered the stars, we made a civilization that spans across the infinite void. We built true harmony between species.
We thought we'd seen the last of Celestia, but as a desperate mobile colony on the fringes of known space came to discover, we were wrong.

It is time to finish what was started by our forefathers.

Based on TCB: Not Alone, by Starman Ghost.

This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.
