The Grand Duke of Pompeii did a lot of calculations, but he never thought that would be his downfall.
The Imperial Bank of Qin was under the Grukos royalty's control. It had a good reputation and most nobles were willing to store their money there. However, most of the Grand Duke's people were up to no good and had most of their wealth converted into either magic nuclei or gold, which were stored in their own homes.
While Emperor Chanake never sent anyone to the Grand Duke's turf to search for any evidence, but he was able to speculate that over half of the wealth in Pompeii City did not pass through the Imperial Bank.
As such, the emperor resorted to using three marquises to cut off the Grand Duke's relations with the southwestern nobles.
Saleen finished patrolling the camp outside of the city and found the soldiers reliable. There were also ample mages, so it would not be a problem to hold such a small city down.
