Although the reasoning behind the prince's visit to the nobles was obscured behind bright smiles and gestures, the visitation was still warranted. The nobles were out of their domains and in the domain of the Royals; the Royals had to make sure everything was in order.
The visits were going to be brief meetings, as the prince's entourage would be visiting most of the high-ranking nobles present in the Crownlands. They could not waste too much time on one noble.
Naturally, there were nobles the Royal Family favoured more than the others. While not entirely exonerated, they were on the positive side of the king.
One of such nobles was the Duke of Vawns, Duke Jason Strall. This duke had once upon a time handled the issue surrounding Baron Zeke when Caleb had genetically crippled the baron.
