This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.

A Warhammer 40k Crossover. Not a brutalization fic. A Brony's First Warhammer fic. Gore will be as light as possible.

In the nightmare future of the 41st millennium, there is only war. There is no hope in a galaxy filled with terror and fear. When three fillies from the magical, peaceful land of Equestria are suddenly thrust into this living nightmare, they must adapt in order to survive. They will sacrifice everything they know and love in order to keep themselves alive.

War will change them.

And the Marks of War will stay with them forever.

"It is not the Horror of War that troubles me but the Unseen Horrors of Peace."—Imperial Thought of the Day

Nopony has heard from Fluttershy for three months. Not Rainbow Dash, not Rarity, not even Pinkie Pie. Her friends have been tending to the cottage and her animals, keeping it clean and organized, but even with Twilight's constant magic scans and a semi-constant guard search Equestria-wide, no hint has been found of where she went, how she vanished, or why she didn't tell anyone. Some ponies even think, in their darkest nightmares, that she might be dead.

Then she shows up one day, very definitely not dead, but just as definitely not the same as she was.

And does she have a story to tell. Boy, does she ever...
