Hello, everyone, I'm Dark Unicorn, and bringing in Commander Shepard from Mass Effect trilogy/Legendary Edition, which is one of the best games you've ever played, or never heard of, depending. Yeah, somehow, both of those are true.
Anyways, she's traversed the galaxy multiple times, saving it 3 times, and thus, is going to be quite confused to find herself where much of the galaxy isn't explored and humans are unheard of.
