 Composed of 12 students, this class was given responsibility to steer the Liebe Delta into the Geduld as part of the station's regular system maintenance.This maneuver (called the Dive) was considered so routine it was entrusted to the Zwei, under supervision from their instructors.The Dive was sabotaged, and was ultimately a failure, with the instructors all dead and the Zwei, as the most advanced students in the Liebe Delta, forced to take control of the station and later, the Ryvius.
