In the year 18 BBY, a conflict erupted between the Paccian Governance, representing the Paccosh sentient species, and a contingent of the aggressive Grysk species, who sought to enslave the inhabitants of the Unknown Regions planet, named Sunrise. This engagement transpired as a direct consequence of the Paccosh slaughter, where the majority of Grysks on Sunrise were eliminated.
This particular conflict is referenced within the pages of Thrawn Ascendancy: Lesser Evil, a novel released in 2021 and serving as the concluding book in the Star Wars: The Ascendancy Trilogy authored by Timothy Zahn.
