The Cybernetic Ghost of Christmas Past From The Future is a robot, and a ghost, and from the future, who talks about the past, and now must explain to Rarity about the origins of Hearth's Warming Eve to Rarity. Will he succeed?

No, as she already knows about the origins of the holiday, and it's July

Warning, wall-o-text in this story, and utter nonsense as well.

Just a one shot because I was bored.

The Vanguard of Hell. Humanity's mightiest military as of 3182 Third Age (BC, or Second Age, ended in 6047 BC, and the year after was 1 Third Age, for reference). Their massive ships and their powerful, armored Vanguard Marines prove more than a sturdy defense against the alien hordes that want nothing more than to destroy us. When a Vanguard Mega-Cruiser, the VONS Ram Of Your Gates, crash lands on Equestria, drawing the attention of the hostile S'riiv'ya Empire, the confused human soldiers and the even more confused pony residents must learn to work side by side if either are to make it out alive.
Also, what the Vanguard Marines look like:

Corporal Andrew White has served as an ODST for longer than thought possible, and he has seen things that would drive any normal man to insanity. Hours after returning to his platoon after recovering from an injury on the planet Reach, he is thrust into combat yet again for humanity. Will he make it through the last hours humanity seems to have, or will he be killed in action in a valiant last stand?

(be gentle it is my first story)
