The Plague Doctor

The fear of disease and contagion - The Plague Doctor wears a beak-nosed mask (if it even is a mask) and long coat. Sometimes, his presence will manifest as a mental disorder or hypochondria.

The Plague Doctor is known to enjoy festivities involving costumes such as carnivals, as he can spread diseases among the patrons without seeming unusual. He can sometimes be heard chuckling to himself, but he rarely makes a sound other than this. However he has been shown to communicate by controlling insects or rats to arrange themselves into words.

An early quote about him: "Perhaps the cloak hangs to the ground, concealing however it moves; it leaves no footsteps, only a broad, shallow ditch scraped clean of anything remotely biological. Those who interact with him are likely to become, not diseased, but hypochondriac, and to hallucinate sensations of things moving on or under their skin. Only if it doubles back on its trail, and you find it a second time, does true disaster follow."

The Plague Doctor has servants called "Oathbreakers." Lesser Oathbreakers are "Plague Bearers" or "Night Surgeons," while greater Oathbreakers are called "Mad Doctors."

His domain is known as the Crumbling Castle.
