Those messages had been sent to each leader of their races. The only one that I was leery with were the Vampires. Vampires were a people who were among the oldest race who branched from the fey. Along with the Veela. The problem being that Vampires didn’t have an exact hierarchy of leaderships. The Veela were always led by the Matriarch, a woman who showed her prowess in battle and her wit in debate. Then her family was considered the ruling family till they were challenged. As far as I know, no one has ever opposed the Delacour’s.
