Yep, it's official. I'm bloody insane. I'm starting yet another Harry Potter fanfic. And this time, it's mixing the insanity of Magical Britain with the insanity of Aperture.

I am far from the only person to do a crossover between Harry Potter and Portal. In fact, there's even a fanfic called Raised by GLaDOS that I will admit inspired many elements of this fic, including the basic premise (though unlike that work, there will be no bashing, and Harry will be adopted by GLaDOS at a later age, along with other differences). But this story actually began because I wanted to do some Harry and Hermione shipping.

I considered doing a pure Harry Potter fanfic with the above pairing, but I was afraid that I would ape many elements of Less Wrong's Harry Potter and the Methods of Rationality. Plus, writing pure Harry Potter fanfic is hard and boring, partly because everyone else had probably done what you're about to do before, and occasionally far better than you ever will. I considered a post-canon crossover, but decided against it. I wanted to do a more intelligent Harry who would end up in Ravenclaw (as would Hermione). And as I mused, I finally hit upon the combination of Portal and Harry Potter.

I'm setting the universe of Harry Potter ten years after canon. That is, instead of 1981, Voldemort killed Harry's parents in 1991. This is because GLaDOS canonically came online in 1998. So, apologies to the purists, and I hope you get over it soon.

Anyway, time for my disclaimers. Firstly, as with all my fanfics, there will be heavy annotations.

Secondly, there will be spoilers for both Portal and the Harry Potter series. You have been warned, don't come crying to me.

Finally, the following is a fan-written work. Portal and Harry Potter are the properties of their respective owners. Please support the official release. Otherwise, GLaDOS will make you her test subject…
