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.

Chaos Lord Crull of the World Eaters appears in Equestria for unknown reasons (probably due to Warp travel gone awry). Stranded on this strange world, he slowly discovers the meaning of the word 'friendship' as he forms bonds with a certain pink pony.

Sepia Tock is an artisan, friend, and citizen of Ponyville. He is not, however, Doctor Whoof.
This is his story

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

When a mansion appears out of nowhere in the outskirts of town, The Mane 6, are all invited to a housewarming by Specter Yield, the owner of the strange mansion. Hours after they leave to attend the party, the Cutie Mark Crusaders find themselves in this mansion. Eventually, Sweetie Belle finds herself alone in this massive mansion, trying to save her friends, and discovering the truth behind this haunted mansion. Will she be able to rescue her friends... and possibly all of Equestria from the ghostly presence?

When Rarity is overwhelmed with making designs for an agriculture exhibition, she turns to Applejack for advice. But when she gives Applejack a hair style treatment in return, the apple farmer lets her accent slip from southern drawl to sophisticated Manehattenite. The result? More fancy parties than you can shake a candy apple at!

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?
