"No idea. Last anyone saw him he was flying off with an unregistered TARDIS full of temporal weapons and a "zombiefied" Surgeon Master. Whether he survived the encounter, I couldn't say. I looked into the matter once I returned to Gallifrey proper, and as far as I can tell, no one has seen or heard from him. Of course, Arkadian being the kind of person whom he is, that doesn't mean much. He could just be in hiding. Or, he could be dead and his stolen TARDIS tumbling, lost, through the Vortex forever. Frankly, at the moment Gallifrey has bigger things to worry about."

Bigger things than a known temporal crook with a massive stash of temporal weapons. That was how bad things have gotten.
