The Nexis, except they're not quite human. From the very beginning, the player's goal was to get home. Along the way, they will have choices to make, secrets to expose or keep, sides to choose, and some will forge their own path. But all will face a harsh reality. Their lives are changed forever. And home is where they least expect to find it.
