Thrawn's guard

A death trooper squad was assigned by Emperor Palpatine as the personal guard of Grand Admiral Thrawn, who was in command of the Imperial Seventh Fleet. They notably participated in the Battle of Atollon in which they attempted to capture the rebel leadership. Some time after the battle, the Spectres undertook a mission to Lothal to gain intelligence on the new TIE/D Defender Elite and infiltrated the Lothal Imperial airfield.

When Thrawn arrived to watch a flight demonstration of the Defender Elite, the Spectres were exposed when trying to steal its flight data recorder. Thrawn ordered his death troopers to secure the fighter, but it was too late as it was already in the air. They were also present during the liberation of Lothal where Thrawn, the Chimaera, and Ezra Bridger all went missing into hyperspace.

After traveling through hyperspace, the guard and all other personnel on board the Chimaera arrived in a distant galaxy and settled on the extragalactic world of Peridea where the guard remained active well into the New Republic Era in 9 ABY, however they were reduced to only two members with both being resurrected by the Great Mothers at some point years prior.
