The Vampire King's Werewolf Bride
"Azazel tried to wake up the ancients for years. But he failed many times. Last time, when Victoria was offered, he tried a different ritual. The blood of Victoria, offered in sacrifice, stirred the slumbering power but fell short of rousing the ancient from its deep sleep.
"Her blood agitated the ancient but couldn't wake him up. All the while, they kept feeding some vampires and their blood. But one day, suddenly, a werewolf was offered to that ancient. There was a movement. From then on, few werewolves and vampires were being offered."
