Adventure, mayhem, magic of unknown origins. Oh, and talking ponies. These are the strange events that have brought three friends together into the wildest holiday that anyone could imagine.

It starts as a small Halloween chat, where they showcase their costume designs to one another. However, due to events outside of their control, they soon find themselves in a new land during a turbulent time.

Now trapped in a case of mistaken identity, these friends find themselves thrown into the deep end, when a royal wedding they’re asked to assist with is suddenly interrupted, and the three of them soon find themselves on an extended holiday from any sense of reality they ever knew.

We now have our own An Extended Holiday TVTropes Page:

(This story is a Novella taking place in the Guardian story universe. This story continues with the sequel Legion.)

Tempest Shadow had heard the rumors. Stories, told in frightened whispers by traders and wanderers, in the taverns and around campfires. The stories told of an almighty champion, a monstrous creature from far beyond the stars, that had come to defend Equestria from its enemies. The stories told it had slain dragons by the hundreds, broke the savage beasts of the Everfree like twigs beneath its boots, and torn down titans and monsters alike with its wrath. They said it wielded weapons that could turn mountains into gravel, and seas into desert. That it was clad in armor, that neither the sharpest blades, nor the mightiest magics, could pierce. The rumors said it was unstoppable, relentless, beyond the power of mare or beast to oppose, that it was. . . a god. Tempest had laughed at the rumors and stories, as she flew toward Equestria at the head of an armada, intent on the conquest of her weakling former homeland. Never once did she give the obviously absurd campfire tales even the slightest credence.

Twilight may have had a bit too much to drink one night and accidentally brought a human named Arc from Earth to Equestria. They have much to teach one another. That is... if they will accept him into their society. Time will tell if humans and ponies can truly live together in harmony.

BE SURE TO START WITH "VOLUME 1 - CHAPTER 1"!

This is quite a long story I originally wrote for my wife as a Christmas present two years ago. Work on it has continued over the past year, and just recently hit 1,000,000 2,000,000 3,000,000 words. I'll upload it chapter by chapter as fast as I can translate them. The Equestrian Odyssey contains many characters from the show and comics, as well as a number of original characters I dreamed up to fill various roles. I hope you enjoy the first volume of my first ever story as much as my wife and I did.

One of my readers liked the story so much that they decided to write their own alternate version of events. Their story can be found here...
