This year's new students at Thor's Military Academy arrive in the small, idyllic town of Trista aboard the Imperial Railway, and make their way up the hill to where the school's campus resides.
The students gather in the auditorium, where the distinguished Principle Vandyck greets them with a speech about the storied history of the school, and the legend of its founder: the late, great Emperor Dreichels.
After the speech, a staff-member instructs the students to refer to their guidebooks for instructions on where to go next, based on their uniform color. The majority of the students have no trouble with this. The commoner students in green uniforms file out, followed by the noble students in white uniforms.
Remaining behind, are exactly ten students in red uniforms, who were not given guidebooks, and therefore have no instructions about where to go.
