Lok Durd, a weapons developer and general in the Separatist army, conceived of the Defoliator as a means of eradicating living troops and terrain while leaving the battle droid forces unscathed. Once detonated, a Defoliator capsule creates a growing radius of destructive energy that scorches all living matter in its path. To launch these specialized warheads, Durd developed the DDT -- the Defoliator deployment tank -- a modified AAT that can support a heavy artillery launcher as its primary turret armament. For increased stabilization, the tanks lower skirt extends further back than a standard AAT, increasing the length of the vehicle to over 12 meters.
Tee Watt Kaa's tribe of Lurmen landed on Maridun -- an uncharted world -- to escape the bloodshed and violence of the Clone Wars. Tee Watt Kaa believed in non-violence and non-aggressive solutions. The Lurmen colonists carved out a peaceful existence on the plains of Maridun, harvesting enormous seedpods to use as shelter, extracting vital oils within for nourishment and medicine.
Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are unquestioning of orders, and easily controlled. The soulless ranks of their battle droid armies consists of tall, thin robotic soldiers with exposed joints and bone-white or rust brown metal finishes that gives them an eerie resemblance to animated skeletons. Battle droids are very efficient, and can be controlled from centralized command centers, like the enormous Droid Control Ships used by the Trade Federation. They are dim-witted, often suffering programming glitches that give them quirky personalities that are too slow to adapt to enemies like Jedi Knights and clone troopers.
Count Dooku was a menacing Sith Lord and central figure in the Clone Wars. Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power. Dooku voluntarily left the light side behind and became Darth Sidious’ dark side disciple, taking the secret name Darth Tyranus and leading the Separatist army.
Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.
In the final days of the Republic, the galactic government had grown so huge and corrupt that any attempt at change required radical thinking and extreme actions. Outlying systems that saw no benefit from being part of the Republic despite paying heavy taxes, began to rebel. This undercurrent of disgust towards Coruscant was seized by a charismatic leader, Count Dooku. The former Jedi rallied together these worlds in a Separatist movement that saw the departure of thousands of systems from the Republic. When Dooku's alliance was secretly backed by corporate titans that offered their unlimited droid armies to the cause, the Separatists emerged as a major threat to the Republic, and the galaxy tipped towards full scale war.
