Sounds like a solid starting point to me too. A fellow Vampire Count player, eh? Then I shall destroy you, for all the evil you have & shall cause! What, you seem confused? Maybe if you my Blood Dragon background, you'd be running now...
Just a thought, if he was a Astrolagist, he'd make a living out of gazing at the stars. I've just checked my copy of the VC army book & since they can only take Lore of Death or Necromancy, THe whole spell effects part might take a little more explaning.
The background for my Blood Dragon, then Demonicus, is that he was one of the 4 vampires who followed Abhorash away when Lahmia was destroyed, his also changed wife & daughter's fate unknown to him. When they were ordered to go their own ways, he first went to the lands of the Orcs, felling innumeral greenskins, always looking for a better chalenge. He then moved on to the Chaos wastes, receiving Abhorash's call after defeating the extremely powerful predasesor to the latest Chaos supeme Lord.
Having proved himself worthy of Dragon's blood, he headed off back to the Chaos Wastes, his sences clouded with pride. Suddenly, his wife & daughter, with a collection of their Necromantic followers, sprung their trap. Captured, with no excape, Demonicus could only watch as they performed some unknown ritual. Suddenly, he was hit with a wave of guilt & remorce, remembering every man, woman & child he had killed. His wife informed him that she had just given him back his soul, & that they had also reminded him of his past & also who he was before he was changed. Realising what he had done, he vowed to right the wrongs he had committed.
They now travel around, undoing the evil he & all other Vampires had committed. All his lesser vampires have vowed against feeding on humans, instead running piggeries for blood & a means of hiding, along with several human assistants who help run the farms. While the male vampires follow the path of the Blood Dragon, the female learn to become Necromancers, allowing for strong teams of hunters.
As for Demonicus, having fed on Dragon's Blood, he no longer needs to feed, allowing him to stalk his next target without pause, normally using his victim's own cloud cover to hide from the sun. Also, having regained his soul, he decided to change his name back to what it was when he was human. He is now Angellus, the souled one. Slayer of Vampires.
In case you didn't guess, I got a fair amount of insparation from Buffy & Angel. I just hope it gives you some ideas. Heym maybe if I fix my Fantasy case & you go to Perth GW, we could even have a game. Of course, you'd have to know who I am...
