Who’s Who on the Shadow Council: Grand Admiral Thrawn

Although unseen in this week’s Mandalorian, it’s heavily implied there is a major seat at the table in the Shadow Council for Grand Admiral Thrawn… whenever Pellaeon’s promises of his return actually come to pass, that is.
A former officer in the Chiss Ascendancy who was tasked to leave his people’s territories in the Unknown Regions to explore a potential alliance with the then-nascent Empire to combat another threat in the Unknown Regions, the Grysk Hegemony, Thrawn rose through the ranks of the Imperial Military to become a Grand Admiral of its Navies. Tasked with rooting out the nascent insurgent organization that spawned on the planet Lothal, Thrawn vanished alongside the Jedi apprentice Ezra Bridger during an engagement between Rebel forces and Thrawn’s fleet, sent through hyperspace to parts unknown by a herd of beings known as the Purgill.
We’ll be seeing him soon enough.
