Commonwealth Rocket Group
 
Weird Science has already been mentioned as being the main Arcane Background in the Frozen Skies setting, there are possibly others that may be covered at a later date. Course using Arcane Backgrounds in Frozen Skies will be optional depending on what sort of game the GM wishes to run, though I still wish for there to play up the 'Pulp Science' aspect.
