Although no match for standing military forces of developed star systems, the Free Brotherhood was strong enough to wreak havoc in a number of small, single-system star nations.
In the 1433 PD in the Megan System the first skirmish between the Free Brotherhood and the Manticore System Navy occured. The Free Brotherhood's scouts encountered two Manticoran frigates on a survey mission in the Megan System. During the following battle, one of the Manticoran ships was destroyed, allowing the other to escape and return to its home system. The aroused Manticore proved to be a much tougher opponent that what the Brotherhood was used to, so the raiders eventually moved on towards the Haven Sector in search of easier prey. The Free Brotherhood raided and exploited Ramon than. Few years later the Free Brotherhood raided Zuckerman System. (Companion, MA1)
