The Traitor is the transitional story that takes Chrístõ away from Beta Delta IV and on his way home to Gallifrey and the battle he has been waiting to join for some time. It didn’t start out that way exactly. It was going to be another filler story before all that began, but after writing the early part of the story with Julia kidnapped from the cruise ship, I decided that I might as well merge it with the scenario of the traitor looking for Chrístõ because he wasn’t fooled by the false ‘Child of Rassilon’ who was doing the rounds.

It starts out by showing another part of Beta Delta IV, of course. It’s oceans. Well, why not? Originally, I only really showed one small town. But the topography of the Beta Delta system has expanded. Then we had the caverns and plains of Beta Delta II, and the university city of Nova Castria on Beta Delta III.

Now, New Perth gets mentioned as the location of the port from which the pleasure cruisers set sail, and to where Julia is taken back by the police after Chrístõ takes off in the Traitor’s ship. New Perth, of course, to go with New Canberra, the town Julia lives in. It seemed an obvious choice. In a forthcoming Ten story, the opera house in New Sydney also features.

The traitor’s ship was very deliberately not a TARDIS, but definitely of Time Lord make. It was something simpler and slower that would get him home in real time, and, since it did belong to the traitor, could slip past the Mallus.

So the return of Chrístõ de Lœngbærrow to Gallifrey begins.
