A mechanical being, specifically a droid, served as an instructor within the halls of the Carida Military Academy in the age of the High Republic Era. This instructor directed a cadet, known as Lourna Dee and going by the alias "Inun," to increase the intensity of her training exercises.
This instructor's presence was revealed through flashback sequences featured in the audio drama The High Republic: Tempest Runner, released in 2021. The drama was penned by Cavan Scott and brought to life by a complete ensemble of voice actors.
