It's been a week now, and life has already returned to normal... well, as normal as can be expected. People go about their lives as if nothing has happened, completely ignoring them. I don't blame them; I want to ignore them too. But I can't. I, and a few others like me, were selected for certain duties by them. I can't tell you how I know I was selected; I just know. One of them hovers near me constantly, as if watching my every move, studying me. It told me that I was in charge of my community's water supply, and led me to my new home at a dam they heavily modified.
