Venus Brown

 was one of Iziah Brown's six wives. They lived in Eternity, California in 1880s. Peri Brown had an ancestor named Iziah Brown, and when she met the family, she wondered if Venus was her ancestor.

Iziah and his wives took Josh Larson and Peri to a cave to see the Fountain of Youth. They were surprised by, who had been seeking the Fountain to repair the injuries he sustained on Sarn. When Peri spilled some of the water, the dinosaur fossils in the cave turned into living dinosaurs and attacked everyone.

The party, except for Dana, escaped in the confusion. Back at home, they were attacked by the Master's hypnotised townspeople. The Fifth Doctor suggested they shock the people out of their hypnotism, so Venus and Wanda grabbed various men and started to kiss and hug. (PROSE: A Town Called Eternity)
