In 25 ABY , a duel was held between Prince Isolder and Archon Beed Thane on Reef Fortress Island . Isolder won the duel , and , as a result , the Hapes Consortium joined the New Republic in the war against the extra - galactic Yuuzhan Vong invaders . Description . Reef Fortress Island was a small island in an ocean on the planet Hapes . It was near Dragon ' s Teeth , a group of sharp rocks jutting out of the ocean . It was surrounded by reefs and was only accessible by boat . Wild dewberries grew on the island , and it had a small cove that was good for swimming . The island got its name from Reef Fortress , a private shoreside retreat of the Royal Family of Hapes that served as a stronghold in times of emergency , which was located on the island . Near the fortress was a generator station that provided it with power and a deflector shield . History . Tenel Ka , the Hapan princess , spent some time with her parents on Reef Fortress Island as a young girl . Later , in 23 ABY , Tenel Ka , along with her friends and fellow Jedi trainees Lowbacca , Jacen Solo , and Jaina Solo , sought refuge on the island after a bomb went off in the Hapan matriarch ' s royal residence , Fountain Palace , where they had been staying . The matriarch ' s personal ambassador , Yfra , and some Hapan Honor Guards accompanied the youths to the island to watch over and protect them . During their stay there , Tenel Ka , Lowbacca , Jacen , and Jaina spent some time swimming in a small cove that Tenel Ka knew of from her earlier vacations on the island . At the suggestion of Yfra , the friends took a trip out on the ocean in a wavespeeder that she , unbeknownst to them , had programmed to go into an area of dangerous carnivorous seaweed . Yfra hoped to use the seaweed to kill the youths as part of her plot to overthrow the Hapan Royal Family . The young Jedi were able to escape from the seaweed using their lightsabers and knives , and Jaina and Lowbacca manually drove the wavespeeder back to the island . Later , Ta ' a Chume , who was the Hapan matriarch and Tenel Ka ' s grandmother , arrived at the island in her own royal wavespeeder . That night , Bartokk assassins arrived at the island in an assault craft and invaded Reef Fortress after destroying the deflector shield generator and cutting off power to the fortress . The assassins , who were sent by Yfra to kill the matriarch , trapped Ta ' a Chume in her bedchamber . Jacen , Jaina , Lowbacca , and Tenel Ka saved the matriarch by helping her climb out the window of her bedchamber . They then found a small wavespeeder and fled the island , with the assassins following in their assault craft . Jaina and Lowbacca , who were piloting the wavespeeder , decided to drive into Dragon ' s Teeth in the hope that the assassins would crash on the rocks . After this failed , they steered the wavespeeder into some carnivorous seaweed , which killed the assassins who were following them . Ta ' a Chume then drove the wavespeeder to Fountain Palace and arrested Yfra before she could promote herself as the monarch . In 25 ABY , Isolder , the Prince of Hapes , and Beed Thane , the Archon of the Inner Rim planet Vergill , which was a member of the Hapes Consortium , participated in an honor duel at Reef Fortress on Reef Fortress Island . Isolder initiated the duel by slapping Thane across the face for insulting New Republic Ambassador Leia Organa Solo and Tenel Ka , who was Isolder ' s daughter . Isolder won the duel during a sudden death round that the referee had called . As a result of the duel , the Hapes Consortium decided to enter the war against the extra - galactic Yuuzhan Vong invaders . Behind the scenes .
