Yarvelling

Yarvelling was a famous Dalek scientist.

Under Minister Zolfian, he developed a mobile war machine for the war against the Thals. When a meteorite storm detonated the neutron bombs, Zolfian and Yarvelling survived in the war council chamber.

Two years later, they emerged from shelter to look for surviving Daleks and destroy any surviving Thals, but they found the surface of Skaro to be devastated, and they quickly contracted radiation sickness. They were discovered by a mutated Dalek survivor inhabiting the war machine Yarvelling had developed. Yarvelling and Zolfian rebuilt the war factory, started a Dalek production line, and made a special casing for the first Dalek, who declared itself the Dalek Emperor. The two humanoids died of radiation sickness just as the casing was completed. (COMIC: Genesis of Evil)
