Chief architect (The Time of Angels)
From Tardis Wiki, the free Doctor Who reference
The Doctor once had dinner with the two-headed chief architect of the Aplans, (TV: The Time of Angels) not unlike how one Doctor had dinner with a Tersuron architect to bribe him. (TV: The Curse of Fatal Death)
The Eleventh Doctor later recounted his dinner with the Aplan architect to River Song in the Byzantium. (TV: The Time of Angels)
