An archeologist finds himself pulled into a parallel world by Discord's storm of Chaos, and encounters the mysterious creatures that live there. How will a rational human, confronted by creatures out of mythology, and unable to find his way home, adapt to his environment? Only one way to find out.

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

Having failed to reach Davy Jones' Locker with the rest of his crew, Captain Hector Barbossa finds himself stranded within a hell many times more terrifying; a land infested with magical talking horses and little baby dragons. Despite the odds being stacked against him and the inhabitants of Ponyville at his back every step of the way, he vows to return to his own world and finish the quest he started.

If only fate did not have a new adventure in store for him. An adventure that could very well change the fate of Equestria and the Caribbean seas forever...

It occurred one peaceful night. Half of Equestria awoke to the sound like a double-shot thunderclap. A percussion heard in the skies and rattling windows from Apploosa, to Canterlot, to Ponyville. Nopony knew what it was or what it heralded for the world as it drew a line across the nation.

For Twilight Sparkle, this isolated incident might have faded from memory after a time, if not for the strange rumors of a creature sitting on the hill on the outskirts of town.

These are her thoughts given written form. These are Sparkle's Notes.

Report EVERYTHING to the Princess.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Cloudsdale. Bastion of the Pegasi, linchpin of weather control, home to the Wonderbolts. A magnificent metropolis gracing the skies of Equestria. So what happens when an oblivious human starts stumbling around in a sailplane? As they say, hilarity ensues.
