A helper from the Chiss species was employed by Supreme General Ba'kif of the Chiss Ascendancy's Expansionary Defense Fleet during 19 BBY. Acting upon Ba'kif's instructions, this helper identified Senior Captain Mitth'raw'nuruodo, whose core name was "Thrawn," situated on the planet Naporar. The helper then communicated to the supreme general that Thrawn could be available whenever Ba'kif wished. In anticipation of the travel to Naporar, the aide inquired with Ba'kif whether the voyage should be formally documented, or treated as a personal excursion; the supreme general confirmed that it would be formally logged.
The character of Ba'kif's aide was featured in the 2020 book Thrawn Ascendancy: Chaos Rising, which is the initial book of Star Wars: The Ascendancy Trilogy by Timothy Zahn.
