Brotherhood Mortalis
this mercenary organization was founded some twenty-five years before the Battle of Yavin, and was believed to have had membership numbering well over 20,000 members spread across more than 100 worlds. What made the Brotherhood Mortalis unique was their simple set of rules and and guiding principles. Among these principles was the requirement that any Brotherhood member, who encountered another wounded member who identified himself, had to administer or provide medical treatment to the wounded member. Despite its simplicity, this rule helped ensure that Brotherhood members stayed on to fight harder, a trait that made them valuable to their employers.
