From the adventure's overview: This mission was designed to be run for four starting characters based on the West End Games Star Wars Roleplaying Game (2nd Edition, Revised and Expanded). It is set approximately six months after the Battle of Yavin. The background for the players is that, through whatever spurious methods they have come up with, their characters have all wound up on Sullust, been recruited by the Sullustan underground movement and are waiting to be introduced to their Rebellion contact, Siene Symm.
