The Argento Kingdom is not as powerful as it was in the past. The current royal family now has fractured its trust with each other when trust should be the foundation of all vampire hunters. Since vampires can easily masquerade as humans, vampire hunters must learn absolute loyalty to those that fight with them.
The Argento Kingdom has fallen quite a bit, but it still retained some of its power because of the solid foundations of the royalty of old. They were also supported by the Old Vampire Council back then, but it stopped when most of them preferred to sleep instead of watching over mankind. Now that the royal family got reduced by half by the Crazed Blood Queen Akasha upon her awakening, the Argento royal family could barely keep their kingdom in check as a lot of key individuals died.
