During the three weeks that had passed, Lyle had mostly focused on improving his own strength, but he didn't forget to get more information on the noble houses that Zeldick had written down on the paper he had given him.
They were the ones that were least loyal to the crown, and the chances of getting their support were much higher compared to the other noble houses.
Lyle had used his servants to slowly gather information, he had, of course, gone out himself as well and managed to find some more info before deciding to go and meet some of the heads of the noble houses.
As minor nobles that were lower in rank compared to the Oslo family, it wasn't challenging at all for Lyle to sneak into their mansions and gain a private 'meeting' with their respective heads.
