The Black Plain Medal
Upon hearing Queen West's question, Minos wasted no time and got to the point. "I am in search of original techniques for array masters. Unfortunately, I couldn't order Black-grade techniques in the Flaming Empire because of some setbacks, but I want to resolve this before I finish my trip."
"Original Black-grade techniques?" Joan asked, knowing why Minos wanted to talk about this with them rather than doing his business directly with local array masters.
Any array master capable of producing their techniques could trade them as they wished. But many followed the recommendations of some larger organization that held power over some necessary resources...
At the same time, since it was not interesting to negotiate this kind of technique with anyone who had just the resources, many would simply not do this kind of business.
