Would that technically mean that --at a high enough level of blood-- one of the two might inadvertently end up targeting and accidentally manipulating the blood of another? There are only so many types of "souls", so there's always the possibility that you could mix up two of the same kind....right?

Otherwise, I'd have assumed all nations with blood-magicians would have them in their own individual Corps...but since that's not the case....
