I heard about this story on, of all things, the kids radio station we listen to on the way to preschool. It got me thinking, what a cool (or cruel) twist for a witch hunter monster! Haven’t quite figured out how to turn it into an adventure. Maybe something about a mission to the Russian steppes that goes wrong and leaves the cadre caught between the beast and a horrible storm? Maybe the unicorn is a terrible variant of the behemoth? I dunno, but there is something here.
