Instructor Goran was the overseer of Skystrike Academy, an elite Imperial Academy for TIE pilots. He was unforgiving with his students, but also blind as to what was truly going on under his watch; it took a surprise visit from Governor Pryce and Agent Kallus to root out an undercover rebel and three defectors, which was a great embarrassment for Goran.
Sabine Wren was a Mandalorian warrior, explosives expert, and graffiti artist -- qualities that came in handy as one of the first rebels against the Empire. Part of the Ghost crew, Sabine used her gift for bomb-making to great effect against the Empire, and would often mark her work with spray-paint tags. Her classic Mandalorian armor was notable for incorporating her own custom stylings, reflecting her creative-meets-rebellious spirit.
The Empire utilized simulator pods to run their cadets through specific scenarios and training missions. The pods were, essentially, standalone cockpit pods of TIE fighters; they could be moved a full 360 degrees to recreate the experience of flying a TIE, and featured immersive, on-screen visuals that could be monitored by instructors.
