Custom witchcraft was indeed one of the means to make money in Colin's plans.
This idea came from Shelley who was standing in front of him.
"It's a requirement from Darren's Commission," Shelley continued.
Darren's Commission was an underground trading market with a membership system, and Shelley was one of its members.
With such a membership status, Shelley had many others; she revealed that she should have at least ten.
Aside from occasionally trading witch tools and magic potions, the main focus of such underground trading meetings was still knowledge exchange.
Although it sounded very grand, based on recent understanding—
The highest knowledge traded within these underground organizations was usually only Second Rank, and perhaps only Third Rank knowledge could appear at best.
There was no help for it; the Supreme Council's control over knowledge was just too stringent.
