White Eyes

In a world that seems average, there is a race whose eyes are pure white. What does this mean? How did this happen?
Imara, also known as Mara, knows something is wrong. Murder, Sudden Death, and Suffering is common now. Nobody seems to care. Because, it doesn't matter much. The government have people to blame, so why go searching for the real murderer? It turns out the murderer is right in their backyard. Everyone is so busy doing what they are supposed to, and murder is just a small casualty. Nobody cares, there is no point to care. Until the whole world starts to feel the effect of the Cadisha, the white eyed race.
