Count Dooku voluntarily renounced his commission from the Jedi council. He was a Political Idealist and believed the
Jedi were weakening themselves by serving as corrupt an institution as the Republic. So, when he left, he banned thousands
of systems together building up a growing seperatist movement threatening to split the republic. Dooku, when he left, had
secretly been receiving training from Sith master Darth Sidious.During the battle of Geonossis Dooku fought Yoda,however,
he was unable to find an advantage in combat. Dooku then used a toppling crane to endanger Obi and Anakin. As Yoda used the
force to save them, Dooku escaped. He then met with his master to tell him that the Clone Wars had begun.
