Magrillo

Magrillo was a Lurker who lived in Vanezia.

BIOGRAPHY
Whilst living in the city of Vanezia, Magrillo found the remains of a Rokathia black box, believing it to be a fallen star. The device sang to him, telling him how to build an opera house, and an automatic orchestra. Magrillo then built androids, who he employed to abduct people from the city, whom he would use to power the device. The device would then transmit a mathematical equation into space.

When the Doctor and Rose arrived in Vanezia, they met Frederico Gobbo, and came across the black box device. The Doctor managed to cause the device to overload and expload, killing Magrillo and allowing all the musical ability the device had absorbed to be transferred to Gobbo's mind, giving him musical talent.
