The MandaloriansThat's... pretty self explanatory. A culture of warriors, forged across millenia and renowned not only for their weapons but for their honor, their dedication,and their fighting prowess. They are the Spartans of Star Wars, and their arrival on the battlefield is not an event to take lightly.As for planets, they'd likely have a small cadre of heavily defended worlds for a nomadic people who ply their trade as mercenaries and bounty hunters.
