Generator Guard Drones or GGD are great machines or drones created for the very purpose as stated in the name, to guard generators. The X-nelian race created many generators to power their civilization when they were alive, whether it was for technological purposes or simply to power the civilization. The X-nelians always feared the loss of power so thus created Generator Guard Drones to protect these very important generators. It is believed that there were many, possibly hundreds, of generators scattered across Atylo. However, since the X-nelian War, many important facilities and cities were destroyed by Dorn. The few facilities that remain were believed to be of great importance to Dorn.
