The Palace Guard, serving on the planet of Aaloth, consisted of guards tasked with safeguarding the First family and their palace throughout the High Republic Era. Under the instigation of Twi'lek spicerunner Bala Waleen, this Guard launched a coup d'état, executing the reigning family and placing Bala in the position of Keeper of Aaloth.
The audio drama The High Republic: Tempest Runner, released in 2021 and penned by Cavan Scott with a full voice cast performance, featured flashbacks that included the Palace Guard.
