A blaster, rumored to have belonged to the Sith Lord Freedon Nadd, is infamous for allegedly causing the deaths of more Jedi than any lightsaber. This blaster was considered a particularly "vile weapon".
Within the game's mechanics, utilization of this weapon is restricted to characters who are associated with the dark side and have attained a Sith prestige class, specifically (Sith Lord, Sith Assassin, or Sith Marauder).
