Villages in the sun-baked Barrens helped fund the construction of this incredible device, able to summon storm clouds from a clear sky. The rainmaker is so large that it has an engine and wheeled tracks that allow it to be driven from town to town like a vehicle, with a small cabin on the front that acts as a control room for the machine and living quarters for the two-person crew.
When the rainmaker is activated, clouds immediately begin to form and gather in the sky. Within an hour the clouds become thick and heavy with moisture. Heavy rain begins to fall shortly thereafter, and it will continue to steadily in a 2-mile radius centered on the device. In particular cold weather, the rain will manifest as snow.
Side effects of operating the rainmaker include heavy winds and the incredibly noise generated by the rainmaker when its in operation..
