Well Seara and I were both thinking, I'd like to work on the Carpathian's first... I have a lot of information on them, so even if you haven't read the books, you can manage. They are generally very arrogant, very strong, powerful have various magic and think their women should do what they say. Of course they are going to find that a little more difficult with modern day mates....
Carpathians are similar to vampires, they drink blood to live, don't really eat, and can't take the sunlight, but unlike Vampires, they don't kill to feed. And they are protectors of the world, even if the world doesn't know it. Vampires are Carpathians who have lost their souls and live for the kills now.
Each Carpathian male loses his ability to see color and feel emotion around the age of 200. And then after that, he can only regain those things if he finds his "Lifemate", the woman who completes him, who is the Light to his Darkness. He must bind her to him and becomes rather jealous and possessive and protective.... With the birth of fewer and fewer female Carpathians, many males have gone rogue and turned Vampire, the only fix for this is to kill them. Those who remain hunt down the Vampires and destroy them. Now they have found that Human Females with Psychic powers are able to be turned to Carpathian, thus the issue with modern women vs, men who still think women should listen to them and do as they say.
