That is quite the happy coincidence.
I'm trying to breed a vampiric line for all the breeds of dragon at the moment. So far I have a Fae/Pearlcatcher pair (Amadeo and Elizabeth, the parents of your dragon) and a Skydancer/Pearlcatcher pair (Amandi and Iskra).
I haven't gotten to far with the lore but so far I can tell you this;

The entire clan is based in the Southern Icefields.
Vampires, being undead, don't worry about the cold but the living do. They use this to their advantage to lure wandering folk, beast or dragon, towards what they think is a welcome rest from fighting the blizzards. Step past the threshold into their domain and you probably won't return, at least not how you entered.
All the dragons in my clan have the same genes: Iridescent, Alloy or Shimmer, and Capsule.

Amadeo (father), the diminuative Fae, is a shadowy rouge. He was one of the first and is well-respected within the clan. His small size and quick, deft hands make him good at his job. He was drawn into helping create the clan by Amandi (male Skydancer, leader).
Elizabeth (mother), is a potion maker and is Amadeos' mate. She is confident and skilled.
The two met soon after the clan was formed as Elizabeth, who was wandering the icy wastes at the time, was looking for a lair to call home. She fled from her birth place in the Scarred Waste land. Fleeing from place to place, she eventually crossed into the Southern Icefields and found herself lost in the snow and ice. That is when she met Amadeo who was out on one of his bouts of 'treasure hunting' (stealing). Feeling bad for her Amadeo bought her to the newly formed clan, which consisted of Amandi, Iskra and himself at the time. The two soon bonded and formed a pair.

Amandi, the clans' leader. is suave and sinister. He doesn't often leave the lair, preferring to wait for his prey to come to him. He his highly respected and his word is final.
His mate, Iskra, is timid and seldom speaks. Amandi is extremely protective over her, to the point where he will lash out in a rage should anything threaten her. Iskra is magically inclined and specializes in healing.


Since I am still working on breeding more pairs and different breeds I still have a lot of work to do.
Hopefully this is enough to give you something to use in your own lore.
