Brotherhood of Mutants
The Brotherhood of Mutants is a team of mutants dedicated to the cause of mutant superiority. They employ any means necessary to achieve their goals, including violent action against anti-mutant forces. The Brotherhood was founded originally by Magneto, but, nominally, dissolved following his arrest and imprisonment in the wake of the Liberty Island incident. The Liberty Island attack also brought the Brotherhood into the public eye -- and earned them a spot on the FBI's terrorism watch list.
OOC Note: The Brotherhood, as their name suggests, tends to consider themselves more of a family than simply an organization -- though given that they're a group of murderous terrorists, they're the kind of family that won't hesitate to kill you if you betray them. Joining the Brotherhood ICly is a serious commitment, not a day job. While there is room in the faction for a lot of different levels of OOC involvement and no OOC requirement to have any particular level of commitment to scenes and plots, ICly there is no easy way to leave the group once you have joined -- once you know who all these wanted terrorists are, their homes and their secrets, just quitting is not a simple road.
Please take this under serious advisement before joining the faction, as IC desertion or betrayal will very likely be met with severe IC repercussions.
