Clash of Dimesions: Dawn of an Era

Have you ever wondered if you were really human? If you were a completely different species entirely?
Well, I didn't until only recently. There's a fine line between normal and not, but my situation is MUCH worse. My name is Sarah Lynx, I've developed strange powers, and own a strange device that was transplanted into my arm, almost magically over night, labeled Hydra. The wasteland has never been more dangerous, new beasts, some larger than the remaining buildings from the nuclear bomb.

An odd red storm is appearing downtown, Black shadows in the sky, large beasts summoned from a light?
What the hell is happening?!
