Meeting up with Twilight and her friends, Beckett and Castle try to deal with their new bodies, the citizens of Ponyville and all the insanity that the Mane 6 seem to attract, all while trying to find a way home.

Hearth's Warming Day.

This day, one of the most magical of days, is about family and love and togetherness and remembering the bonds of friendship.

It is also about demanding presents, showing up your family, freaking out over the tiniest detail and fighting the rush of a thousand other ponies that seem to want to do nothing more than ruin the holiday for everyone else.

This year, Twilight is getting to host her family's Hearth's Warming Day Dinner and she wants everything to be perfect. But as she sees what the holiday does to her friends and those around her, Twilight begins to lose the spirit of the season and wonders just what good is a holiday that seems to turn everypony into jealous, greedy monsters.

Join Twilight in this look at what modern life has done to the holiday season and how easy it is to reclaim the magic back.

This story is set in the Scootaverse (Which includes The Many Secret Origins of Scootaloo and The God Squad). Neither of these stories are required reading but it will help.

This story is a sequel to The Many Secret Origins of Scootaloo

After everything that happened the last few months, Twilight has enjoyed some much deserved peace and quiet. But when Scootaloo disappears without a trace, the newest Equestrian Princess suddenly finds herself forced to lead the hunt for the missing filly. Aided only by Spike (and hindered by everyone else), Twilight must travel the globe and discover just where Scootaloo is.

Of course, that's easier said than done. Every pony seems to have an idea about what happened to Scootaloo and are ready to share their theories... whether Twilight and Spike want to hear them or not!

From the creator of 'The Many Secret Origins of Scootaloo', 'The God Squad', and 'Crisis of Infinite Twilights', comes the sequel no one asked for or even thought would happen (including said author!)

My thanks to CrowMagnon for inspiring this story. The rest of you can blame him as well.

Who is Scootaloo? Everypony knows about her present, but when it comes to her past there are as many different answers as there are questions.

Is she the love child of two star-crossed lovers? The last hope for the future? The child of a broken home? A mysterious figure fighting a war no pony knows about? Or is it something else entirely? Is she even a pony at all?

Twilight Sparkle decides to ask everypony in Ponyville and find out about Scootaloo...and the stories, rumors and gossip she gets will leave her wondering how the truth can ever compete with fiction.

My thanks to Page Turner for the new story cover!

Thanks to all my readers and fans for all the support and help I have gotten! I am truly touched.

This is a side-story for defender2222's Crisis of Infinite Twilights, and is written with defender2222's blessing. It will make no sense if you haven't read that story up to the start of the Ponpan arc, but the authors involved make no guarantee that doing so will make any more sense.

While Scootaloo and the God Squad sail to Ponpan to find another batch of alternate Twilights, those left behind at BUTTS headquarters (Bureau of Undoing Trouble from Twilight Sparkle) decide to play a game to pass the time, get to know each other better, and possibly get very, very drunk. Not necessarily in that order.

(Rated Teen for some sexual conversation between characters later on, but nothing explicit.)

This story is a sequel to The Many Secret Origins of Scootaloo

When Scootaloo's attempt at flying causes her to crash into Twilight's lab, it sets off a chain reaction that causes Twilight to disappear, leaves the library in shambles and Scootaloo knocked out. A wave of purple energy rips through Equestria, leaving all to wonder 'great, what now?'

When Scootaloo awakens, she learns from the Bureau of Undoing Trouble from Twilight Sparkle that this world's Twilight is gone... and in her place are dozens of Twilights from different dimensions, tearing across the land. Worse, Nightfall Eclipse, a wicked Twilight from the antimatter universe, is assembling other bad Twilights to form The League of Evil Twilights, who seek to take over Equestria.

Now gifted with the ability to track down these Twilights, thanks to the explosion, Scootaloo will seek out these visitors from other universes in the hopes of sending them home and getting the real Twilight back.
