Lurker

Lurkers were a race of humanoids.

HIstory
Some Lurkers lived in the city of Vanezia, including Magrillo, who found a Rokathia black box. It told him how to build an opera house and an automatic orchestra. He built androids to abduct people, whom he used to power the device. Magrillo was killed when the device overloaded and exploded. (COMIC: Opera of Doom!)
