This was something I wrote as the author and co-writer in Fanfiction.net almost a decade ago. The time line is after season 4 and the 1st EqG movie.

When a spaceship crashlands in Equestria , it's up to Doctor Whooves to analyze the ship remains and contact the aliens in charge.

Rated Teen for implied owl death

A Season 10 of MLP:FiM that retcons The Last Problem and G5, and basically pretends as if both never existed.

Twilight moves back to Ponyville and decides to rule from there, after feeling homesick.

Spike has been feeling like he and twilight have been growing apart and sorta blames the rest of the mare 6 for taking her away. Can he make a bond with them of his own and have them as best friends? Meanwhile Twilight has been feeling guilty of leaving Spike depressed lately. But what happens when her friends start to take Spike from her?

After the defeat of Nightmare Rarity and the nightmare force purged for good, and Twilight's coronation into being the princess of friendship, Everypony believes that the days of Nightmares are over...but what happens when Rarity transforms back into her Nightmare form? Can Spike help her control her new form and can old bonds be fixed between him and Twilight?

Spike has been Twilight's loyal Friendship Ambassador for many years, sorting problems and building bridges with other nations.

Sadly, the customs of his ancestral home remain a mystery to him. On a diplomatic visit to the Dragon Lands, Dragon Lord Ember decides to enroll Spike in a ceremony that all young dragons must pass, the communion with the deity of the dragons.

Yet, in this unfamiliar realm, a world of dragons he knows so little about, Spike is forced to grapple with profound questions of identity-who he truly is, what he aspires to become, and whether he can ever embody the essence of what it is to be a dragon.

Surely speaking with a God can't be that bad?

Set sometime before The Last Problem during Generation 4

(Takes place within the universe of My Little Pony Friendship is Magic: What If? and its many sequels. Familarity with them is recommended, but not required.)

It's back once again, that series which has always asked and sought to answer the question "What if things were written differently?". This time, rather than episodes from the show, it's tackling the big 2017 theatrical movie.

Twilight Sparkle is excited to host the very first Festival of Friendship, right in her hometown of Ponyville. But she's also starting to have doubts about how great of a princess she truly is in the wake of a costly mistake made not too long ago. Luckily, she has her friends by her side along with her faithful companion and adopted family member Spike.

But just as everything's in place for the festival to begin, things go awry. A hornless unicorn named Tempest Shadow launches an invasion on behalf of an evil known as the Storm King, and she soon sets her sights on all four alicorn princesses: Twilight included. Twilight and her friends only barely manage to escape.

Facing a threat unlike anything they've ever dealt with before, Twilight hopes to recruit a new ally in the form of Queen Novo, and her friends insist on tagging along. Their journey will take them beyond the borders of Equestria, to lands never seen before, and will test their friendship in ways unimagined. Can the magic of friendship survive when it is placed under extreme stress?

As always, no disrespect is to intended to anyone at Hasbro, DHX, Boulder Media, or to anyone involved with the movie's creation: Be it from a writer, artist, or voice acting stand point.

This story is a sequel to Blues Clues: Meeting a Magician.

It's getting close to Mother's Day in Canterlot City. Spike and Inferno have their gifts ready. But Twilight is having a hard time figuring out what present to get her mom. Time for you to play Blue's Clues!

Now all is said and done, and Twilight is due to ascend to the throne in just a few weeks, there is just one final task that stands in her way. Despite the support of her friends and family, she has sworn to undertake this journey by herself...
