After an accident, Rarity and Twilight are thrown in a race against time to stop their transformation into changelings before they become part of Chrysalis' swarm forever.

In a moment of weakness, Chrysalis had more than a taste of Shining Armour's love. 11 months later, Twilight Sparkle finds herself a brand new niece by way of 'A small foal in a basket on my door step'.

The royal court of Canterlot welcomes its newest member with open forelegs: the human philosopher Voltaire, from Earth.

On Earth, Voltaire is known as the greatest enemy of tyranny in the history of literature, and a legend in his own mind.

On Equestria, the court betting pool is giving him a week before the Princess banishes him to the Moon.

Note: This story doesn't have sequels per se, but there are a couple of short follow-ups set in the present day ("Parade Coverage" and "Secret Histories"), and a prequel of sorts in "At the Inn of the Prancing Pony".

To save her sister and her faithful student, Celestia herself must travel into the ancient tunnels beneath the ruined castle in the Everfree Forest. She, and the guards who accompany her, must face the dark, twisting corridors. Still, what was Luna and Twilight's purpose at the old castle? Why were they unable to return of their own accord?

And what watches Celestia from beyond the light's edge?

After the changelings' failed invasion of Canterlot, Twilight tries to soothe some of Ponyville's rampant paranoia by casting a spell to prove there are no imposters hiding in the town. But her spell leaves her in an alien body, facing a mob of angry ponies who just don't believe her when she says she is Twilight Sparkle.

Or, at least, she was Twilight Sparkle, anyway...

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Discord had one last trick up his sleeve to play before being locked up again: he's turned Equestria's timeless protector into its most dangerous threat. The kindhearted princess that ponies loved and adored is gone, replaced by an alicorn of iron and blood that forged Equestria out of the fires of pre-history.

Can Twilight Sparkle survive being the student of a pony who never had need of the magic of friendship or will she be forced to sit on the sidelines as Equestria irrevocably changes around her?

Rainbow Dash isn't having a very good day. First she was in some dark place, then it turns out she's in the hospital. Oh, and she's apparently blind now.

Eventual Twidash!
