Screams and whispers can be heard in the sky, making everyone on the streets stop what they are doing. Some people thought is just a prank, and others think aliens are coming. Then the sky starts turning dark, and a mass of horrifying clouds appeared in sight. Source of the screams and ghostly whispers came from this cloud of pure evil. People started to run into shelters, and some just stood still, looking up into the sky without any movement. After a while, sirens can be heard everywhere in the city, and public announcements are been made, telling everyone to stay indoors.
