In the time that had passed since Minos and Abby's return to the Dry City, many issues had developed on Stone Island, some positives, some negatives...
Firstly, all the agreements those noble families wanted to make with Minos through Elen were organized after Abby, and he returned from their business trip.
At that time, during the couple's journey, Elen had already communicated those powers of Minos' conditions, having even negotiated for several weeks until they reached a compromise.
And after all that was resolved, almost a year had passed since then!
In the meantime, Minos had done a lot of business with those powers, including making some demands that would disrupt Charles' life, among other matters as well...
And they had hardly had any problems in this business relationship for most of that time.
