Types of Hadeon's relationships

Mallory's eyes bulged like a startled owl as she witnessed Hadeon's fingers dive into the vampire's chest. Hastily, she averted her gaze, not keen on witnessing the gore that the pureblooded vampire relished. Suddenly, a rustling broke the silence, and she peeked back to witness Hadeon rising, clutching one of the vampire's legs.

With a casual tone, Hadeon remarked, "The villagers could use a bit of warmth. A bonfire made of vampire limbs ought to do the trick."

Hadeon began to walk back, dragging the vampire by his foot, who now mopped the forest floor. Mallory trailed closely, afraid of getting lost in the dark. Curious, she asked,

"Master Hades, do you know who this person Erebus is?" 

"I might have heard his name," Hadeon replied nonchalantly as he reached for his cigar case with his free hand.
