Classic Doctor Who

Placed on trial by his peers, the Doctor is forced to watch events from his past, beginning with an incident on Ravolox involving the curiously named Marb Arch.

The Doctor has an appointment with the Immortal, while Peri finds herself caught up with Glitz and the Tribe of the Free. Meanwhile, Merdeen begins to question all he believes.

With the black light converter destroyed, the Doctor fears for the planet's safety and needs to find the Secrets of the Sleepers and discover why they are there.

The Doctor is foxed by Drathro's logic so it takes Glitz's blunt lies to buy them some time until Ravolox can be saved. Meanwhile the Tribe make a foolhardly attack on Marb Arch.
