From publisher blurb: Alyeska. A frontier land largely at the mercy of the savage Wulvers since the end of the Great Darmonican War, barely enough soldiers left to defend the rump of the Commonwealth's once extensive colonial holdings. With many towns cut off and large swathes of territory overrun by the beasts the safest form of transport is by air, but the breakdown in law and order as given rise to scoundrels like sky pirates and bandits. Alyeska's frozen skies are increasingly becoming a dangerous place to be. Carve out your own place in the wild blue yonder with rules for building your own aircraft and an alternative take on air combat. Additionally; new Edges, Hindrances, Gear and a different take on Weird Science can be found within the pages of this book. Requires the Savage Worlds core rules.
