The Baron eyed the commander go one to rant about Sapphire city and the Sapphirine Cult but said nothing and kept it to himself that he and the rest of the devouts of the Sapphirine prince knew that it would take much more than this for Ghan and his men go actually pose a threat to their rise.
You see, Sapphire city had expressed it quite clearly that they had no interest in involving any of those who they had taken on the faith to come to their aid.
This had nothing to do with protecting them and was more about Sapphire city being willing to take care of this issue on their own.
The take over of the vast majority of the Duchy by taking over every county had not been to bolster Hal's forces and had been for nothing more than the gathering of faith.
