Caerdroia (audio story)

 was the sixty-third story in Big Finish's monthly range. It was written by Lloyd Rose and featured Paul McGann as the Eighth Doctor, India Fisher as Charlotte Pollard and Conrad Westmaas as C'rizz.

It was essentially the "beginning of the end" of the Divergent Universe arc. Significantly, it depicted the Doctor's recovery of the TARDIS, which had been absent from the Eighth Doctor's adventures since AUDIO: Scherzo.

The story began to "pay off" the Divergent Universe arc by explaining things like the Interzone, the Kro'ka's motivations and fears, how a universe without time worked and the Divergence itself.

From a production standpoint, it was notable for its highly complex sound design, which had to depict abstract environments, including the Doctor's own mind. It also afforded Paul McGann the chance to play three different versions of his Doctor, each primarily exhibiting what Charley called a "mode" of his character. Thus, the story had one Doctor that was a bit surly and paranoid, another that was bouncy and excitable and another that was more or less the "regular" Eighth Doctor.

The story was written by Lloyd Rose, giving Caerdroia the distinction of being the only full length performed Doctor Who story authored by an American woman.

Publisher's summary
Self-exiled to a new universe, separated from the TARDIS, opposed and manipulated by the Divergence and their agent the Kro'ka, the Eighth Doctor has been struggling to work out the nature of the cosmic game in which he's an unwilling pawn. Now, at last, he has a chance to find the answer — and regain the TARDIS!

Threatened and desperate, the Kro'ka abandons his behind-the-scenes machinations to confront the Doctor directly. But will both of them lose their way in the maze of the strange world in which they find themselves? A world in which a clock may have a cuckoo but no hands, a labyrinth imprisoning a paradox, and a Garden of Curiosities reveals something the Doctor has never seen before.

As the Doctor faces these challenges, Charley and C'rizz provide valuable help. But with the TARDIS itself at stake, the Doctor reaches deep inside himself to find some surprising new allies.
