Are the vampires race specific?  Meaning which of the races can and cannot become vampires.  If not then there might be certain traits each race could have, like enhanced strength (humans, dwarves, orcs, trolls), enhanced agility (hobbits, elves), enhanced intelligence (humans, hobbits(?), elves) etc.

since "romance" is shown in the genre I'm guessing there's some action going on between the two sides... right?

Does the "gray death" kill instantly or is there a time until death?

Lastly, according to the plot is the queen a pure blooded vampire, a vampire God or a person turned vampire (WHAT IS RACE SHE).
