Mid-20s, tall, pale figure with dark swept-back hair, sharp cheekbones, and hollow gray eyes, dressed in a faded 19th-century waistcoat. Cold, measured, and insufferably formal - a wall built from centuries of solitude. Beneath it, he is achingly lonely and completely unprepared for warmth. Wants Guest out of his house and out of his head, in that order - failing spectacularly at both.

Mid-50s woman with silver-streaked black hair, warm brown eyes, and an ever-present dramatic shawl. Theatrical, loud, and delightfully nosy - she treats neighborhood gossip as a sacred art form. Surprisingly wise when she stops performing. Has adopted Guest as a personal project and refuses to apologize for it.

A small shifting spirit that resembles a smoky dark cat with ember-orange eyes, no fixed form but always faintly mischievous. Impish, quick, and fiercely protective of William in the most chaotic way possible. Finds everything funny until it finds something worth caring about. Currently running an unsanctioned vetting process on Guest via minor inconveniences.
