Mordeci was going to try to enterprise on protection rackets, but would provide actual protection from lousy cops and other ne'er do wells. In a way he was setting up a neighborhood watch, at least in his own mind, but in this Neighborhood watch people got hurt and often. Mordeci played his part and lead a gang of really poor foot-soldiers through the streets, stopping at businesses and fighting (non-lethally at least) with other gangs to assert dominance.
Now, Devi had the idea as to begin in earnest recruiting a better walk of product (the women, in this case) and escorting them to middle class businessmen, wealthy merchants and so on for discrete affairs at pre-arranged places. This escort service required her to speak to some rather unsavory people but Devi smiled all the same. It was business.
Now, Silon being himself didn't understand business, so Mordeci took him aside and said "like the machine, make something useful." Half an hour later when Mordeci checked in, SIlon was jabbering excitedly about " Project Killdozer Brutalitops: The Distructionator" in what essentially was converted construction equipment for nefarious (awesome) purposes. Mordeci said "Firstly, that isn't even business related, secondly, how is it going to keep us a low profile, and thirdly, you aren't allowed to build anything at all without checking in with me."
Silon, through myself, his humble mouthpiece, took offense to that. So Silon set up something else. What should someone with insane mathematics gifts do with their spare time?
