Due to the numerous marriages among nobles, no one would be foolish enough to breach these connections carelessly, especially given how helpful Hudson had been during previous troubles.
Whether it was the favoritism during task allocation or the assistance in procurement of materials, it made everyone realize the importance of having supportive relatives.
Unless something unforeseen happens, the rate of intermarriages between the Koslow Clan and the provincial nobles will keep increasing.
These are steps the Dalton Family can't replicate. After all, the Alpha Kingdom promotes monogamy. To forge numerous alliances through marriages, one would need to have a lot of offspring.
In fact, even with many heirs, Earl Piers wouldn't be able to form extensive alliances with the provincial nobles.
The Koslow Clan does this because they have not fully integrated into the circle of major nobles. Apart from Hudson himself, the other members of the Koslow Clan are not yet widely recognized.
