The Imperial Experimental Precipitator Drone Mark I, also known simply as the EPD-1, was a prototype model of precipitator drones, which were probe droids designed to "inject" precipitation into the clouds of otherwise dry worlds in order to combat drought.

Alternatively, the EPD-1 droid was also designed to remove precipitation from a cloud, gradually bringing on the effects of drought and damaging a world's agriculture.

History
In 13 BBY, thousands of EPD-1 were deployed to the Outer Rim agriworld Minasuba, which was suspected of supplying resistance groups in neighboring systems with food. There, the drones gradually removed the precipitation of the clouds, and by 11 BBY, the majority of farms on the planet were forcefully closed as the ensuing drought made farming on the planet impossible without the use of greenhouses. Thousands of Minasubans then migrated to neighboring systems, where the majority were arrested by Imperial authorities under the excuse that they were traveling without passports.

When confronted by the Imperial Senate, Imperial authorities claimed that the EPD-1 drones were not Imperial, though were stolen from Imperial laboratories and modified to cause the drought so that pirates could then reap whatever was left behind on the world.
