My Mistress is Vampire Royalty

Long ago, during the 18th century in the city of Ancient Romania, when the humans had found out about the supernatural world, there was a fierce battle going on between the normal vampire called the Magars and their sworn enemy Shades. Shades are evil vampires that have black beady eyes, long, sharp silver-tip finger-like claws, long, sharp silver fangs that they use to drink blood from both humans and vampires, as well as have a long, rock stone solid-like body that it almost indestructible. The Magars have red eyes, normal fingers and hands that can change to claws when their eyes become a dark red color, they are able to use magic however they only use it for defensive purposes, they have normal fangs that they use to drink human blood as well and they are able to regenerate from any wound that they suffer from.

In the Vampire World, they have something called Royal Families and a Vampire Queen that rules over the entire vampire realm. There are a total of twelve royal families and each royal family has a royal symbol and a specific magic element that they are able to control except for the Ancient Royal Family whose royal symbol is a Gold and Silver Wolf and their magic is called Crimson Dark Flame.

The Magars were struggling to survive and on the verge of extinction due to the Shades creating more of themselves and slowly eradicating the Magars royal family lines. So in order to keep this from happening any longer, the vampires made a blood pact with the humans and the humans that the twelve royal vampire families chose became their familiars.
The familiars of the twelve royal families were known as the Twelve Royal Familiars and they wore the royal symbol of the family that they are protecting as well as using the specific weapon the royal family they are guarding uses to train with.
