Griswald the Undertaker
Townsfolk always know when Griswald is coming from the stench that precedes him, for Griswald is a ghast. He is quite urbane for a carrion-eating undead beast, wearing a well cared for but threadbare formal suit and speaking with a pleasant high class accent.
The townspeople put up with Griswald and his stench because he provides a necessary service, and he otherwise leaves people alone. He transports away unsightly corpses from the streets and dwellings of the town and promises them a proper burial outside of town free of charge. No one really believes that he doesn’t turn around and just eat the corpses, but then no one really cares one way or the other.
