Yeah, not too in depth in the Core book about droyne other than their characteristic stats. Droyne are tight knit group both small and large and any group has member that highly specialize in a particular skill set to aid the group's functions. A Worker would take Citizen(Worker) exclusively. A Warrior focuses on Star Marine or Ground Assault depending on what environment they are assigned lifelong. Drones are Citizen (Corporate). Technician would be Scholar specializing in only one of the three assignments. Leaders would be Nobility(Administrator). Sports are the odd ball and can take, but still specialize, in a variety of career choices depending on the needs of the overall society.
If you have a player group of characters, each will play a very specialized role for the whole and probably be the best and most experienced. The most basic group unit is the tyrafelm of six droyne that consist of either a mix of each caste or are specialized in function. Larger groups are multiples of the basic family unit. There would also be NPC droynes filling roles too and looking up to the player for purpose and direction. A starship would be considered an extended family unit of several tyrafelm possibly divided by position, Engineering, Bridge, Gunnery, Troopers, etc.. Remember though, it is a strict caste system. The Leader droyne is the leader and overall decision maker.
Everyone correct, clarify or expand my interpretation.
