Professor Elizabeth Holub was a scientist and granddaughter of Liz Shaw. She lived in Prague in 2050 where she performed experiments with cold fusion with the aim of finding an inexpensive way to provide electricity.

After disturbances around the city's Jewish district, Holub sent a distress call to the Doctor that was answered by the Seventh Doctor and Ace. After learning of her relation to Liz, the Doctor helped her defeat Nápev and save Prague. (PROSE: Fable Fusion)
