Brothers in blood

Azrael and Elijah, both descendants of the well known Vampire Victor, head of the Vampire Council.
He only had two sons ever and while Azrael disappointed him greatly with his lust for power and his total ignorance towards other people Victor always had deep feelings for Elijah, who never felt like fitting in anywhere and always caused trouble. Elijah isn't aware of the fact that Azrael is his brother when he joins the same clan as the blond vampire, who on the other hand is more than aware of it. He deeply despises Elijah and makes his life a undead hell. The hostilities boil over when Azrael chooses the welcoming party for Elijahs own vampire son, the man he truly loves, to tell everyone about Elijah having murdered his real parents in rage back in 1532.
When Victor finally announces Elijah as his heir to the Vampire Council's seat it sends Azrael over the edge. No more games, no more schemes, Elijah shouldn't suffer, he should die... and this time for good!
