Lurker

Lurkers were a race of near-humans.

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