Dal (species)

The Dals were a race which lived on Skaro. They were extinct by the time Davros was alive. A few words in their language were preserved, such as "Varga" meaning "devourer". (BFD: Purity)

The Thals sometimes referred to the Kaleds as Dals, and stated that the Dals became the Daleks. (DW: The Daleks)
