When Ruby boards the first trans-oceanic flight in Equestrian history, the last place she expects to end up is stranded in the middle of Eternity's Crossing in the wake of a horrific zeppelin crash. After a mysterious tower leads her and a fellow survivor to discover a twisted and fragmented city twenty thousand feet below the surface of the ocean, though, a bit of fire and smoke is the last thing she needs to worry about. Between the horrendously disfigured residents and the paranoia of the madmare who once built and controlled it, daily survival in this corrupted utopia is anything but a guarantee. But with the help of some new friends and a few genetic enhancements, Ruby isn't going down without a fight, and in the process might just discover that the deadliest weapon in Harmony is herself.

An adaptation of BioShock for the world of MLP. Written to be comprehensible to anyone, regardless of whether they've played the original game.

Most pirates that stalk the Seven Streams prefer to live only in the shadows, skulking through the skies as daylight dies and striking with brutal efficiency at any helpless merchant vessel in range.

Most pirates that the Royal Equestrian Aeronautical Navy hounds after are ragged, ruthless cutthroats who'd just as soon sell their grandmothers for a chestful of bits and a bottle of rum.

Most pirates that you hear about in stories would flee in terror at the sight of the RES Corona, the -world-famous warship helmed by the most dangerous and determined sky captain ever to fly under the Equestrian flag.

This story is not about most pirates.

P.S. Big ups to Chromosome and CouchCrusader for the editing help. Appreciate it as always, gents.
P.P.S. nitstits, go home.

Diplomacy has failed. Six years have passed Equestria's crowning of the princess of friendship, ushering in a supposed unprecedented age of peace and harmony. The concept of warfare is, to most ponies, nothing more than an unfathomable legend. They have let their guard down.

An unknown enemy has seized the opportunity to attack Equestria with terrifying new weapons of war, bent on taking the fertile land and restoring an ancient order. The valiant efforts of the Royal Guard have given Princess Twilight and her arcane scientists time to research and develop a response to their attackers, and the time has come for that response to be implemented. Utilizing weapons and tactics borrowed from another world, five squads under the command of Princess Luna will infiltrate the forests of the Equestrian Northwest to destroy a revolutionary magical matrix that Twilight refers to as the "radio" - a tool that allows enemy ponies to communicate across vast distances instantly.

Nightmare Two is comprised of three foalhood friends who, rather than be separated from each other in the draft, volunteer to become one of the five Nightmare squads. With their bodies forever altered to suit the needs of their mission, the three young mares join legions of ponies armed with powerful weapons to partake in a horrifying new breed of warfare - Equestria's first in over one thousand years.

Heads up, folks. If you wouldn't mind leaving a comment alongside the thumbs-down, I'd appreciate it. This is my first foray into fan fiction and although it's a hobby I nonetheless wish to get better. :)

Got some FAQ's for you guys as well!

- Alternate universe in which the events of "Crusaders of the Lost Mark" did not occur. (As much as I loved it! :D)

- Numerical age tends to vary with headcanon, but the CMC here were just getting started with their adult lives when the draft went into effect.

- The war is pony v. pony, utilizing firearms and the Equestrian equivalent of a tank. The underlying headcanon is that ponies used firearms similar to muskets and tracked armored vehicles akin to our tanks in times of old, and what the enemy currently employs is essentially the natural progression of these technologies.

- There are no real-world weapons or equipment i.e. "Panzer IV," or "M16 assault rifle." Particularly acute details such as the caliber of weapons are also absent.

- Technology is based on that of WWI with some WWII elements. Firearms are primarily bolt-action.

- The "radio" spell matrix functions as what we know to be a radio, but is not identical.

- All four of a Night Mare's legs are permanently replaced by the augments.

- Night Mares are female. Stallions proved unable to properly animate the limbs.
