As Fluttershy shows Discord her first gray hair, he realizes that his beloved friend is getting older and offers her the ultimate gift.

Spike tells Twilight the news about Thorax's current condition.

She finds it baffling.

Marko and Ishmir are polar opposites. But that’s what makes the Spartans so good together. So good in fact they can take on a whole Covenant space station and win.

Unfortunately extraction didn’t go too well, and the headhunters find themselves stranded on an unexplored planet. Can Ishmir keep the peace with the locals and get the Spartans home; or will Marko cause an interstellar incident?

My money’s on the latter.

The headhunters came, saved the day, and then they left. But in their wake they not only left a pile of Covenant bodies – they left Princess Twilight Sparkle with a spark of wonder. An interest in the galaxy that surrounded her little home planet; an interest in the lurking dangers and the magnificent wonders of the universe.

Unfortunately it seems some of the danger and wonder is coming to visit Equis. So it’s time for the bookish shut in to throw herself into the galaxy to find the warriors who would help her defend her home.

Now with an amazing YouTube reading by the equally amazing AShadowOfCygnus!

During its two year search for Shepard, the lone Geth traveled across the galaxy, exploring worlds both known and unknown. After a blind FTL jump to escape from an Alliance patrol, it found itself in a previously undiscovered system, a system without a mass relay and completely cut off from the rest of the galaxy. It touched down on one of the worlds, a garden-like planet, with the intention of gathering data on any flora and fauna that may have been present.

Instead, it made a remarkable discovery.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

(It's my first time, so be gentle)
