From publisher blurb: The Briton Twins are among the best and brightest the Hegemony has to offer, so it is no wonder they were recruited by the elite Hegemony Intelligence and Surveillance Services (H.I.S.S.). This Faction for Wild Skies: Europa Tempest is available for use in any Wild Skies game. Have your players dive right in with a cohesive backstory for the twins, pregenerated characters, detail of H.I.S.S., new spy gear, and some hints at things to come!
