Yeah, it's complicated. I've got a working theory that it brings you closer to the Singularity, somehow— you might start to show the ability to work with the local "magic".

[Yes she's putting quotation marks on this. Shepard doesn't believe in magic, magic is just a word for something you're unable, or unwilling, to explain. But it's not like she's going to be conducting scientific research anytime soon, and she has to call it something.]

At least that's how it worked for me. It might've just been a coincidence, but the timing is pretty suspicious. It's not so bad.
