The Magisterium is the "teaching authority" of New Babbage Town. The word is derived from Latin magisterium, which originally meant the office of a president, chief, director, superintendent, etc.
The Magisterium is able to teach or interpret the truths of steampunk, and it does so either non-infallibly or infallibly.
'"The task of interpreting what New Bababge should be authentically has been entrusted solely to the Magisterium of New Babbage."'
It is a group of long serving residents of New Babbage who have a clear idea of what Babbage Town is and what it is not.
If you are new to New Babbage, chances are you will be watched with the scrutinous eyes of the Magisterium.
A conspiracy theory popular with those that believe the mayor is incapable of arriving at his decisions independently.
"The Mayor said that because he is a puppet of the Magisterium."
