" " Ahsoka escorts a group of younglings to Ilum , where they will learn from Yoda and undergo a crucial rite of passage : the construction of their lightsaber s . They grapple with both physical and inner challenges as they face the dangerous task ahead of them . " " Plot summary . Ahsoka Tano , tasked with escorting the newest class of prospective youngling graduates to The Gathering , is awaiting her charges at the boarding ramp of the ship which is to ferry them to their graduation test : Petro , a human ; Katooni , a Tholothian ; Byph , an Ithorian ; Ganodi , a Rodian ; Zatt , a Nautolan ; and Gungi , a Wookiee . Their task is to find the crystals for their own lightsaber s in the Crystal Caves on Ilum , the most sacred place of the Jedi . After a short briefing about the hazards lying ahead of them , Ahsoka takes the younglings to the harsh ice world of Ilum . After jointly opening the gates to the Caves using the Force , the group is received by Master Yoda , who opens the ice - covered inner door to the caves . The younglings are given just enough time for one planetary rotation to find the crystal which they will use to construct their lightsabers , or otherwise remain trapped within the Caves as the sun sets and the door freezes over once again . Once inside the caves , Petro in his overconfidence separates from his classmates and sets off on his own , forcing the others to continue without him . Soon after , they reach a chamber with several doorways , and trusting their instinct , the younglings split up into pairs to explore one door each , though unlucky Byph ends up exploring one on his own . Soon the younglings spot their individual crystals one by one , but in order to reach them , they have to pass hazards which at first glance seem impossible to conquer : Katooni has to climb a steep ice wall to get hers ; Gungi has to cross a field of loose ice floats covering a lake ; after plunging down a crevice , Ganodi finds herself in a cave littered with thousands of crystals ; Zatt , trusting too much in his scanner , ends up wandering the caverns in frustration ; and Byph ' s crystal rests in the maw of a hideous creature of which he is too fearful to approach . At first the younglings fall into despair , but in short order they begin to focus on their inner self and succeed in gaining their crystals . In the meantime , Petro has found and retrieved a crystal , but as he exits the maze , already confident about his victory , the crystal he gained melts into a puddle of water in his palm , so he is sent back to find his true crystal . As he chases around , he comes upon Katooni , who on her way back outside has fallen into a small cave blocked by a thick sheet of ice . He leaves her behind in his zealousness to find his crystal , but is quickly plagued by his conscience and returns to help her . By jointly using the Force , they are able to break the ice , but as they prepare to leave , Petro spots his crystal between the ice shards . He sends Katooni ahead , who manages to slip through the bottom gap of the door just before it freezes shut . Before they can all begin to despair about Petro , however , the lost youngling bursts through the ice wall , which has not frozen too thickly to penetrate . As the younglings gather around Yoda , the old Jedi master reveals that the true trap in this test was not the sheet of ice on the inner door , but their own fears and insecurities . By finding and gaining trust , confidence , courage and compassion in their hearts , they were able to escape the traps they have set against themselves in their minds . Continuity .
