Regarding “Snuffers”

“A colloquial term for the tribe of face-thieves that prowls the back-rooms, parlours and sculleries in Fallen London. They are named for their appetite for candles, which they devour – though none knows whether they crave the wax, or the flame. They are searching for something, or perhaps somewhere. Facts are elusive, for they change faces as often as a gentleman changes his waistcoat.”
