Chrysalis had come a long way from absolutely nothing - a humbled bug-horse left to fend for herself in the howling wilderness. But she's not the pony changeling she used to be, and she's set her hoof upon the path of conquest, for herself, for her crown, and for her children minions.

All she had to do was seize the commanding heights of the pony principalities, and feed her brood upon that endless supply of pony happiness which was her birthright, by all that was villainous!

If only her mother didn't keep tripping her up.

Twice, they denied her a great victory. Twice, she was left humiliated and beaten by pony hooves. But if there's one lesson Queen Chrysalis surely learned, it was revenge. If there was a second, it was where to stick the dagger in a loving mother.

But there are some things even she can't foresee.

Rarity is good at making dresses. In fact, she's the best. But even she didn't know that her latest dress would be more than the fashion sensation of the season.

Now she was going to have to add wing-holes to all her outfits, and everypony seems worried about her latest creation.

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

Twilight Sparkle has a secret: her mind is not hers alone.

King Sombra, tyrant of the Crystal Empire, was spared from his destruction. Twilight Sparkle welcomed his severed consciousness into her own, and began to learn from and hopefully teach the fallen unicorn. No one knows what she has done, and now fate has thrown a wrench into her plans.

Back in Ponyville after her coronation as Equestria's newest princess, Sombra refuses to ignore Twilight's new station in life.

Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Celestia has never used her full power.

Ever.

But that might be about to change. Chrysalis has contacted her and requested a meeting out in the middle of nowhere. Celestia expects a trap. In fact, she's hoping for it.
