After I died, Alpha collapsed.

“I was a Vampire Princess, mated and married to an Alpha werewolf. But our child was neither vampire nor werewolf; he was nothing but a scrawny, feral mutt. In a fit of rage, Kaelen killed him and banished me. To save my baby, I drained every drop of my magic and died completely. Five hundred years after my death, Kaelen came seeking my heart to ensure his new Luna could bear an heir. "Five hundred years... has she learned her lesson? Tell her to offer up her heart, and I might just forgive her this once." But when he finally learned of my death, he fell to his knees before my grave, weeping and begging for forgiveness.”
