(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.
