His decision
A Bloody Vampire General has a very high status in the Vampire World for several reasons. One reason is that he has a high status in all the armies of the five kingdoms.
However, there is a more important reason than that, and it is a future reason: the status that the person awarded such a rank could achieve.
When someone is awarded this rank, it comes without stars. He is a true Bloody Vampire General and highly respected worldwide, but he still needs to do more for the Vampire World to be awarded a star.
Still, at the time, his status in all the armies of the five kingdoms was as high as that of a Major General; that's a status a step above what Oliver Jones currently is.
All Kingdoms must pay him every three months according to his status in the respective armies. Likewise, they are obligated to provide him with all the benefits that this rank may have.
