Edge of Empire: From Crime to Consequence
Fantasy Flight Games, who makes Edge of Empire, has released other source books – some are detailed examinations of the individual careers, some look at individual aspects of characters lives such as ships, and some – Age of Rebellion, and Force and Destiny – are fully fleshed out rulebooks like Edge of Empire.
I will be incorporating some sort of “expansion slot” rule for the minor sourcebooks, but you cannot begin with anything from them initially.
The other two sourcebooks – Age of Rebellion, and Force and Destiny – I will unlock for you as part of the campaign. You cannot unlock them yourself.
