One of the two scions of the powerful noble houses that had plotted against Sied was dead.
That left one scion and the young general to be dealt with.
There were more, of course, but they were not troublesome and Lyle was certain that he could kill them with the help of the Emperor who was doing his best to attack the Golden Lion army but was being stopped by Lyle and Nicholas.
The young general was a mid-grade Titled Knight and was not weak at all, the same tactic that Lyle was using to get rid of the others would not work on him thanks to his strength.
As for Iodel and Ulon, Lyle was not planning on killing them yet, only later, when the army of the Golden Lion would make their way back, would he strike, eliminating the two and claiming his revenge.
