Grysk plot to engineer a Chiss civil war

The Grysk plot to engineer a Chiss civil war occurred in the Chiss Ascendancy and nearly led to a civil war among the Chiss species in 18 BBY. The Grysk Hegemony, an expansionist empire based in the Unknown Regions of the galaxy, sought to destroy the Chiss Ascendancy, which it viewed as a bulwark preventing the Grysk conquest of the entire Unknown Regions. To accomplish that goal, the Grysks dispatched the agent "Jixtus" to arrange both infiltration and exfiltration of the Ascendancy and destroy it via a civil war and an invasion. The crisis lasted at least a month.

The plot appeared in Timothy Zahn's 2021 novel Thrawn Ascendancy: Lesser Evil, the final installment of Zahn's Star Wars: The Ascendancy Trilogy.
