(This is a Crossover with Halo. If that genre offends you, you need not read any further.)

Cortana has several problems, and very little she can do to solve any of them. Being stranded on half of a ship in deep space, with the clock on her lifespan slowly running out, she gets desperate enough to try almost anything.

She goes so far as to land her half-ship on a strange astronomical anomaly, in the slim hope of finding a method of FTL travel on it. Now, her latest problem consists of understanding the mind-bending physics of this planetary crime against reason, without prematurely going insane.

Chief wakes up on a new planet, and is, as always, presented with aliens he needs to kill in order to accomplish his mission.

Equestria witnesses the arrival of a large object from space, and has to deal with the fallout of it's destructive crash landing. Though the real threat the object poses is not something anypony could have anticipated.

(Knowledge of the Halo games is advised, though not strictly required.)

I am currently looking for an editor, pre-reader, and/or proofreader, preferably someone who can double check me on the lore when it comes up. Shoot me a PM if interested. I've got a few people who have generously offered their help. Thanks for offering to help make this as good as it can be!
Will update tags as story progresses.
Fair-warning, this story is secondary to my other one and will update less frequently.

This story is a sequel to The Monster in the Twilight

Now that Luna has returned to the throne, and the aftermath of her brief appearance as Nightmare Moon is being cleaned up, the story is over. Right?

Not quite.

Twilight Sparkle had nearly been destroyed in the chaos of Nightmare Moon’s return, but now with the assistance of her five friends, she is facing a fascinating new world filled with wonderful things. No longer the scarred monster who nearly destroyed Canterlot and raged through the Everfree Forest for over a decade, now she has been healed by the Elements of Harmony and is living at the edge of town with her adoptive mother Zecora. Not all the fears of her past can be left behind that easily though, and now she must face the consequences of her actions as she faces the most daunting challenge of her life.

Ponyville.

Letters is a sequel to the alternate universe story The Monster in the Twilight. In this story, Twilight Sparkle exchanges letters with Princess Luna, two ponies with a common problem of fitting in and making friends after the destruction of Nightmare Moon.

Normally I would try to talk you into reading the sequel even if you haven’t read the original story, but in this case, you’ll probably be more confused than entertained. But go ahead. I don’t mind if you don’t read the first story. You’ll never find out what an Urlock is, but that’s fine. It’s your funeral.

After a freak earthquake, blinding lights, and some zero gravity a young man finds himself in Equestria. however due to his shyness he has a hard time speaking to anypony. So, most think he's just some new species of animal.

Oh, and did I forget to mention that he's know as the EverFree's Alpha by some of the inhabitants of the EverFree forest... just checking.

I'm not good at summery's, sorry.
