Inventor of the Crystalline Hyperdirectional Chronometer. 
Specialist in Crystallography and Levitational 
Metallurgy, Prof. Lawkin devotes most of his time to 
private research. He funds his excursions with the controlled 
release of certain inventions that he feels won't upset the 
balance of the public too much. 

The Sartoraeous works as a test bed for many of his unique
 inventions, to the unfortunate (but moderate) peril of several 
of his passengers when things don't work exactly as planned. 
Currently, he's taken to ferrying passengers from point A to 
point B (he's often not concerned with the specifics) for 
the opportunity to test his new 
Crystalline Omni-refractor Motivator. 
Once activated, it should increase the power consumption 
efficiency of the forward motivation of the Sartoraeous
 over 87.3%, that is, if it doesn't cause the stern superstructure
to evaporate instantaneously. 
Prof. Lawkin is sure that won't happen, however. 
Pretty sure. 
Mostly.
