The room exploded into chaos! Suddenly, the whole atmosphere had changed as the different leaders quickly tried to make amends with Kace. He smirked at their behaviour with only served to infuriate them. However, they kept their anger in check to try and placate him. They worried that he would just seek out a new monster tribe to work with if they offended him.
He had succeeded in helping to lay the groundworks for this city, so who was to say that he could not do it again? If he did that, then there was a good chance they would lose a lot of the rights to claim territories once the war was over! Sucking up to him, for now, was obviously the best choice! They only really disapproved of the vampires joining the council because it would mean another split in the potential rewards. Why would they give so much land and riches to only two vampires?
