Occasionally, posts on my history blog cross over with gaming stuff. Today over on the blog I'm talking about The Flying Serpent, or Strange News out of Essex, a facsimile of a 19th-century pamphlet replica of a 17th-century pamphlet about a mysterious serpent in Henham, Essex, with references to the famous Saffron Walden cockatrice. I love incorporating some actual folklore into my Call of Cthulhu or similar games, so let's see what I can do with this thing. You can get it on DTRPG: it's only $1.95 (about £1.20).
My blog has probably more than the higher normal proportion of readers who run or have run supernatural games set in Essex, so I thought I'd mention it.
