Mister Cirvags didn't like the implications of Khan's statement. He wasn't even trying to hide his gradual accumulation of power. Baoway was becoming the new focal location for interspecies politics, and Khan brazenly advertised it as that.
Mister Cirvags didn't mind the arrogance and audacity but had issues with that development. He was a man deeply loyal to his species, and Khan was seizing all the relevance for himself, stealing it from humankind. Khan was hijacking the mutual respect developed throughout years of deals and treaties.
The act wasn't only insulting. Mister Cirvags was aware of the many potential dangers connected to the matter. Khan wielded too much power now, theoretically enabling him to seize even more of it. Humankind's future could be grim if he decided to walk down that path.
