Timothy Zahn penned the brief narrative "Command Decision," which initially appeared in Star Wars Adventure Journal 11. West End Games published it in November of 1996. Subsequently, it was archived on the Hyperspace website.
The narrative commences with Admiral Thrawn, Commander Parck, and Captain Dagon Niriz situated within the Unknown Regions on the Imperial I-class Star Destroyer named the Admonitor. While disguised as a colonial transport, they come across an alien fleet of Ebruchi vessels, headed by a mysterious alien being known as Creysis.
