From publisher blurb: Killing Winter is an adventure for the Brass, Blood and Steam, supplement for the SotC SRD. You will need Brass, Blood and Steam (also from UKG Publishing) and a copy of the SotC SRD in order to run it "as written", though it should be quite easy to adapt to any steampunk or generic games system. This adventure is set in Queen Victoria's Land, the sample campaign background in Brass, Blood and Steam and follows directly from the sample adventure, Diamonds in the Snow.
