The Imperial Training Hall is the setting for the optional Opening Stage of Rosenkreuzstilette. Spiritia Rosenberg returns here after six months of training in the Black Forest, where she is greeted by Iris. Shortly afterwards, Talos swoops down and abducts Iris and Lilli gives chase. Spiritia goes after both Talos and Lilli and eventually finds the forest set on fire; there she reunites with Lilli, who was unable to catch up with Talos. They find Freudia, who explains to them about the RKS's rebellion against the Holy Empire and Orthodox Church. Spiritia disagrees with their way of doing things and defeats her, starting her quest to stop her friends from performing their rebellion.
In Rosenkreuzstilette ~Grollschwert~, Grolla Seyfarth, after seeing that an attack has begun, rushes to the center of the commotion within the Imperial Training Hall to find that Freudia is leading the strike. Unable to convince her that Iris is instigating this war for her own amusement and that the attack against the Empire should cease, Grolla takes it upon herself to stop her colleagues from starting the war and ultimately get at Iris for humiliating her and betraying the RKS.
