The droid was noted by colonel Viyenah as an implacable and silent "tenebrous giant". Entirely painted in black, with two red, glowing cameras for eyes, the one that everyone on Providence called "the Specter" had a monolithic and frightening appearance.
The "Specter" was a mystery, even for the Providence population. Nobody knew were he hid himself nor what he did most of the time, only realizing his presence when they heard the growl of his internal generator. He appeared sometimes, walking toward a unknown goal, occasionally killing someone. None of the pirates ever tried to stop him, thinking that it's a divine punishment that was deserved by the victim.
