Raid on Reef Fortress In 23 ABY , a squad of Bartokk assassins hired by Ambassador Yfra raided Reef Fortress in an attempt to assassinate the matriarch of Hapes , Ta ' a Chume . The assassins arrived on the island in an assault craft , cut off all power to the fortress , and entered by climbing the wall of the stronghold . Jedi trainees Tenel Ka , Lowbacca , Jacen Solo , and Jaina Solo , who were staying at the fortress , killed several of the Bartokks , rescued Ta ' a Chume by helping her climb out the window of her bedchamber , and fled the island in a small wavespeeder . Jaina piloted the wavespeeder into some deadly carnivorous seaweed , which pulled the assassins , along with their craft , into the ocean . Ta ' a Chume then drove the wavespeeder to Fountain Palace , the personal residence of the Hapan Queen Mother , and arrested Yfra . Prelude . In 23 ABY , Lowbacca , Jacen Solo , and Jaina Solo , who were Jedi trainees at Luke Skywalker ' s Jedi Praxeum on the moon Yavin 4 , arrived on the planet Hapes to visit their friend Tenel Ka , who was recovering from a lightsaber accident that had occurred at the academy and left her with only one arm . They stayed at Fountain Palace , the royal residence of the Hapan Queen Mother , until a bomb went off in the dining hall where they were to eat . Because of this danger , the youths were sent to Reef Fortress , a private , isolated sanctuary of the Hapan Royal House , which was located on a small island in an ocean on Hapes . There , the friends were guarded by Ambassador Yfra , who was the personal ambassador of the Hapan matriarch Ta ' a Chume , Tenel Ka ' s grandmother , and some Hapan Honor Guards . Later , Yfra suggested that the young Jedi should take a short trip out on the ocean in a wavespeeder . Unbeknownst to the youths , Yfra programmed the wavespeeder to bring them into an area of dangerous carnivorous seaweed , because she wanted to kill them as part of her plot to overtake the Hapan monarchy . However , Tenel Ka , Lowbacca , Jacen , and Jaina escaped from the seaweed and manually drove the wavespeeder back to the island . Soon after , Ta ' a Chume arrived at Reef Fortress in her royal wavespeeder . The raid . That night , a squad of insectoid Bartokk assassins sent by Yfra invaded Reef Fortress . After arriving in an assault craft , they cut off all power to the fortress and destroyed the generator station , disabling the deflector shield in the process . The Bartokks then climbed the wall of the fortress , entered through a window , and began to attack their primary target , Ta ' a Chume . Jacen , Jaina , Lowbacca , and Tenel Ka went to help the matriarch and , after killing several of the assassins , locked themselves and Ta ' a Chume in a bedchamber with the Bartokks on the outside . Knowing that the assassins would soon break in the door , the group climbed out the window on a fibercord and fled the island in a small wavespeeder . However , they were followed by the assassins in their assault craft . Jaina piloted the wavespeeder into the Dragon ' s Teeth , a collection of sharp rocks that stuck out of the ocean , in the hope that the assassins would crash . The assault craft received some damage , and three assassins fell out of it , but it continued to follow the wavespeeder . Jaina then proceeded to drive the wavespeeder into some carnivorous seaweed , expecting the assassins to follow . When they did , Ta ' a Chume shot at their craft with a small hand blaster she had , setting it off balance . Because of this , the seaweed pulled the entire craft , along with all the assassins , into the ocean . Aftermath . Ta ' a Chume then drove the wavespeeder to Fountain Palace , where she had Yfra arrested and later put on trial . As a result of the raid and her other adventures at Reef Fortress , Tenel Ka decided she had recovered from her injury and was ready to return to the Jedi academy with her friends . Behind the scenes . The raid on Reef Fortress first appeared in the young readers book " " , written by Kevin J . Anderson and Rebecca Moesta , and published in 1996 .
