A treaty was negotiated between the reconstituted Sith Empire and the Eternal Empire by the Minister of Logistics during the Eternal Empire's conquest of the galaxy. The treaty ended the Eternal Empire's assault upon the Sith Empire, but forced the Sith to begin paying a heavy tribute of raw materials and resources, as well as an arms limitation statute that the Sith Empire broke in secret.
The treaty would be nullified when the Sith Empire intervened in the war with the Eternal Empire on behalf of the Alliance against Zakuul.
