Everyone wears a mask. For the rulers of Equestria, that mask must be impeccable for their subjects. Only around their guards can the two Princesses relax ever so slightly, occasionally showing that they are just as fallible as any other creature. For one Princess, the burdens of her own mind begin to make the mask crack. However, when Private Steel Heart notices that it is, in fact, the pony underneath the mask that is beginning to splinter, he offers to help.

He had no idea such help would first involve getting attacked with a large brush.

Warning: Involves slow-burn romances, lots of feelings, comforting moments, adorable affectionate gestures, lethal amounts of fluff, feel-good auras, and a deadly combing implement.
Takes place around Season 8-9 (ish)

Chapters 9-11 now re-written.

Princess Luna is a rather archaic princess. Being a thousand years forward in the world, it is understandable. She always assumed that she would always be an outlier to others, never finding something even nearly as old as her besides books and buildings.

However, she is surprised to discover an object more archaic than her. Far more archaic.

A train.

A rather... famous train.

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.

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now with a TV Tropes page.
