The Unity era was a period of 189 years wherein the galaxy was dominated by the Empire of the Sith Order of Decreto. Beginning in 121 ABY following the death of Darth Abeonis, Dark Lord of the Decreton Empire and head of the Sith Order of Decreto, the Unity era was subsequently named as such following Darth Krayt's victory over his rival Darth Proditor in their war for the throne.
