This story is a sequel to Splashdown

Things have been shaken up by Luna's surprise appearance and subsequent journey to Earth. As the world tries to find its footing in a universe much different then they expected, and as the strange phenomenon of "magic" begins to spread, everyone's having to make some accommodations-- Luna not least, with the Nightmare now an equal holder of her own body; not a great arrangement. But among all this, the attack onboard Hornet lurks, begging the question: Who was behind it? What do they want? And is it already too late to stop it?

(for any G-fans, Xenilla is the kaiju you may know as Spacegodzilla. I changed the name because I got quirked about typing it repeatedly and am writing the story so it can at least be understood by just an MLP or just a G-fan; and thought it get very confusing that one character's name was just another character's name with an adjective. Also... don't pretend it's the most imaginative name Toho has every made)

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

Discord has trapped Twilight in a vast, seemingly unending library. This library has a copy of every spell checked book that could possibly exist. Twilight's only way out of the library would be to find the book that explains how to escape. But when every single idea, story, possibility, and random book exists, how can she find the one book that can teach her how to leave this unfathomably large library?

This fanfic is a crossover based on the ideas presented in the short story, "The Library of Babel," by Jorge Luis Borges, and influenced by "A Short Stay in Hell" by Steven L. Peck.

The sequel to this story is also sequel to A Place for Pinkie.

A Metroid Crossover

A meteor, resistant to magical manipulation, crashes in Equestria, Planet Equis, and soon spreads an unknown poison throughout the land. Containment is all but failing and the Princesses have little power to stop the spread of the Great Poison. The Elements of Harmony are of little use as no knowledge exists of this threat that consumes all life. Help comes from a certain Hunter, clad in metal.

Samus Aran will not only fight for her life as always, but her own sanity as well as these ponies that she begrudgingly starts seeing as allies. New horrors and abilities await her as a reason to fight slowly festers within her, possibly unlocking something she had been denied for so long: Friendship.

Notes and Resources:

This takes place after Echoes. The events of Corruption will have not happened yet. In terms of MLP, consider everything up to and including the Crystal Empire. Princess Twilight does not exist here, etc. The official Metroid Timeline can be found here.

As well, this story references the manga in many places. Reading of it is not required and I try my best to explain the context, but if you're interested, both volumes can be found here.

EDIT: This story was written over two and a half years, beginning in 2013. You'll probably notice the difference in writing as the chapters progress.

The Barrier: a naturally-occurring wave of magic that formed soon after the portal to Equestria appeared somewhere in the South Pacific, enveloping Earth with an inevitable tide that has destroyed all life on the planet, all despite the best efforts of man and pony alike. Now, the ponies are left to pick up the pieces and try to preserve what's left, while averting the vacant gazes of the mindless Newfoals left from one of their failed attempts to save what they could.

But there's one thing that all seem to have forgotten, from the ponies of Equestria to the strange multitudes of species in the universe with their sights set on Earth: and it's that you can't keep a good apex predator down. You can only hold them up a little while...
