However this task is interrupted by an unwanted guest. Not only is Twilight forced to put up with her new houseguest, she's starting to feel a change coming over her, taking over her mind. Can she resist the call of the night, or will she fall entirely into the grasp of Nightmare Moon?

I hope everpony likes this! I had this idea after watching the Season Three premier, and it wouldn't go away until I wrote it! I'm sorry if the writing isn't up to your standards, but I'll appreciate and constructive criticism!
Also romance for eventual shipping.

It's been two months since Twilight and Big Macintosh started dating, and what a wonderful two months it's been. As their relationship blooms, Twilight finds out through Applejack that not all of the Apple family may be keen on a relationship that includes one of their own kin, and a unicorn. Worried about their future together, Twilight asks Big Macintosh for the biggest favor she can think of...to visit his entire family, and see if they can't break old traditions.

This is the sequel to Sparkling Cider, my first fan-fiction. It isn't necessary to have read Sparkling Cider to understand Old Traditions, but it certainly wouldn't hurt!

This story is a sequel to Dusk and Dawn

The Dawn Militia and Nightmare Moon's armies continue to wage war across Equestria under the eternal night. The six bearers of the Elements of Harmony–Fluttershy, Rainbow Dash, Applejack, Rarity, Pinkie Pie, and Trixie–have been blessed with extraordinary powers, with which they lead the Dawn against the tyrant and her reluctant lieutenant, Eclipse.

But it's hardly easy. After all, what place does harmony have on the battlefield?

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

My eternal gratitude to my editor, LordOfTheWrongs, without whom Night's Favoured Child would not be the story it is today.

Now with added TVtropes!

Waking up in an alternate universe in which you are a supervillain can be hard.

Finding out your friends are rebels trying to kill or overthrow you isn't very easy to deal with either.

But trying to solve the situation? That's a real horn cracker.
