Knife&Candle as a tabletop roleplaying game is a dead project, as far as I know.
It's setting inspirations come from Echo Bazaar
, a story-based browser game with a distinctive style. It's essentially Victorian London, only with a heaping dose of weird stuff heaped in on it.
You can play it if you want! It's free and fun, though no longer the rage among storygamers it used to be.
