Summit Class was the name of one of the classes at the Galactic Outdoor Survival School.
Around 17 BBY, the Summit Class became the greatest class ever in the GOSS, managing to get a record in the final trek used as an exam. Warren respected the results and the performance of the Summits. Seven years later, the Twilight Class broke the Summits record in more than one day.
Former Summit student Lunkar An, who had since created his own survival academy, felt his ego shaken after that and re-joined GOSS as a student, trying to "redeem" himself.
