Kavell
From Tardis Wiki, the free Doctor Who reference
Kavell was a Kaled scientist and member of the Scientific Elite who worked in their bunker underneath the Kaled Dome under their chief scientist Davros. He was also in charge of communications with the dome and informed Ronson that the Fourth Doctor and Harry Sullivan had reached the dome.
After Davros had Ronson killed, Kavell began to plot with Gharman to destroy Davros' power. He later freed Gharman, Sarah Jane Smith and Harry from their prison cell. (TV: Genesis of the Daleks)
