Upon the birth of any member of the blood Clan there is an exception, an exception mostly influenced by fate and talent- Holders. You see , members of the blood Clan are descendants of ■■■■■■■ Blood , hence they are called the blood Clan rather than just mere vampires , like snakes to dragons so are the blood Clan to vampires . An equivalent to Vampires to Rust's previous world does not mean they are any thing close to vampires .
However , the blood Clan are similar to vampires in many ways,for instance they drink blood like the vampires but they don't have to, in fact in this world there's a saying common among the blood Clan people said by the current and only queen of the blood Clan to the vampire monarch of that time 'you drink blood because you have to to,I drink blood because I want to'.
There relation between vampires and the blood Clan is that one is a force unevolved form of the other and this had caused many conflicts between both races, but both races still exist in this world but that's a story for another time.
True Blood, a distinct makeup in the genetics of all blood Clan members inherited from their progenitor that grants them many abilities such as being immune to all negative effects from the sun , garlic having the same effect on them as it does on humans, and silver just being a metal Luke any other but with all the benefits of being a vampire except for aging. Of course these aren't enough to make them dragons to snakes, but the having a the transcendent power capacity of a true dragon with the physique capable of holding such power does. All that accompanied by their own racial talents that differs from other's makes them recognised as one of the 10 most powerful races in this world.
Holder, as the name suggests is the racial talent that further widens the gap between the blood Clan and most races, each corresponding to different concepts that make up reality and upon their birth all blood Clan members fortunate enough know through bloodline inheritance their own name and concepts. The majority of the blood Clan are not holders either but they do follow the most common form of having a talent through awakening a talent at the physical age of 18. The bodies of all blood Clan members age like normal humans until their bodies reach a certain physique unique to them that their body has determined to be the best for it then they no longer age, though most blood Clan members look about between human ages 18 to 40.
Being a holder does not mean you can control that concept from the get go and just in general even though certain beings in the blood Clan may make you reconsider that statement. The main benefit that the blood can values from being a holder is the growth bonus that comes with it , blood Clan members and all long lived creatures similar to dragons grow stronger with time so you can imagine the importance of being a holder. In the blood Clan whenever a new holder is born all non holders experience similar phenomenon unique to what concepts the new holders have with the heart beat representing the number of concepts held .
