Dawn of Defiance (Roll20)
Order 66, also known as Clone Protocol 66, was one of a series of contingency orders that the clone troopers of the Grand Army of the Republic were trained to obey without hesitation. The order branded members of the Jedi Order as traitors to the Republic and called for their immediate execution without question or hesitation. The issuing of the order by Supreme Chancellor Palpatine marked the formal beginning of the Great Jedi Purge, and signified the rise of the Galactic Empire.
Almost all of the Jedi were killed by Order 66, and the subsequent Great Jedi Purge threatens to eliminate any survivors.
