Serving as a prequel to The Keeper of Traken, it was notable for exploring the history of Nyssa's home planet of Traken and the wider Traken Union, as well as for being novelist Lance Parkin's first audio story.
To save her life, he must make a desperate journey to the only place in the universe where a cure might exist to heal her.
When even that fails, the Doctor has a choice — let Nyssa die, or make a deal with the devil.
After all, the road to hell is paved with good intentions...
