The Exxilons was the first story in the fourth series of the Fourth Doctor Adventures, produced by Big Finish Productions. It was written by Nicholas Briggs and featured Tom Baker as the Fourth Doctor, Louise Jameson as Leela and John Leeson as K9.

It was also the first performed appearance of the Exxilons since their debut in Death to the Daleks in 1974. This story is a prequel to that story.

Publisher's summary[]

Planet E9874 supports a developing civilisation known as the Tarl. The peaceful, technologically advanced Locoyuns are helping the Tarl develop rudimentary technology. What could be more innocent than that?

When the Doctor, Leela and K9 arrive, they find the delicate balance in the relationship between the two cultures reaching an unexpected crisis point. The spears are flying and the threat of all-out war is in the air.

The Doctor must use all his guile to tread a careful path with Tarl leader Ergu, while Leela and K9 discover an ancient power of unimaginable strength which threatens to tear the minds out of its victims.
