Once important

Mallory leaned in towards Lady Rose, her curiosity piqued and eager for more details. She asked, 

"In love?"

A small chuckle escaped Lady Rose's lips, amused by Mallory's suggestion. "When the devil created him and the rest of us," she said, "he ensured that none of us could alter our true nature—least of all, Hadeon. Love is not something Hadeon does."

For some reason, Lady Rose's words pinched Mallory, even though she was already aware of Hadeon's nature. This knowledge was also precisely why she maintained her distance from the pot of craziness.

Lady Rose continued, "Long ago, Hadeon was captivated by Reagan's blood and took her everywhere. It's not that he lacked other sources before her. In fact, some even suspected that she had changed him. But when she turned into a vampire, she lost her appeal to him since he only kept her around for her blood. I suspect that's why she remains bitter and likely sees you as his next blood donor."
