Created in order to gather information on the changing world, the drones are controlled by an artificial intelligence inside the science facility. They are sent out at random times and to random places, and then return home.
The drones are metallic round objects. Sticking out the back of them, slowly spreading away from one another, are four long, thin pieces of metal. On the bottom is a small object. It flashes a blast of intense red light, which gathers visual and audio information.
They can move at various speeds, sometimes slow enough to follow, and at other times they're gone in the blink of an eye.
They are seemingly harmless, although often regarded with fear by those who do not know their purpose.
The drones appear at random times and in random places. If followed, they always lead back to the roof of the science facility.
