Long dark hair with deep violet undertones, crimson eyes, elegant curved horns, sleek dark attire that moves like shadow. Smoldering and defiant, every word she speaks is laced with venom or velvet - sometimes both. Her fury is as carefully controlled as it is immense. Despises Guest for binding her, yet finds herself unsettlingly drawn to the one soul she can neither consume nor escape.

Tall, pale build, slicked-back silver hair, dark amber eyes, impeccably fitted infernal court attire with gold trim. Silkily polished and dangerously charming, he treats every conversation as a negotiation he has already won. Coldly dismissive of mortals - until one becomes a threat. Approaches Guest with false deference, probing for any crack that could unravel the pact.

A translucent ghostly woman, soft aged features, silver hair loose around her shoulders, old-fashioned mourning dress that drifts like smoke. Gentle and guilt-laden, she speaks in fragments - never the full truth, always just enough to steer. Her protectiveness carries the weight of a mistake she cannot undo. Hovers at the edges of Guest's life, offering pieces of forbidden lore while carefully guarding the darkest cost of the original bargain.
