Melodie Melodies were a humanoid water - based species native to Yavin 8 . The species lived deep within the purple mountains of their homeworld , most notably Sistra Mountain . Biology and appearance . Melodies were hatched from eggs and started life on land . These young Melodies would live around the underground freshwater lakes deep within the caverns and inlets of the moon ' s equatorial mountain ranges until they reached the age of 20 , when they were to complete the change into an adult Melodie ( also known as an Elder ) in an event called the Changing Ceremony . Prior to this , young Melodies who had not yet changed would care for the infant Melodies . This involved gathering trico which was then made into a paste to feed the infant Melodies until they were old enough to eat the silver - backed fish that lived in the pools within the mountain . Young Melodies lived a dangerous life since they were often preyed upon by numerous predators , including the bird - like avril s , the rodent - like raith s , the serpentine reel s , and the spidery purella s . During the Changing Ceremony , these Melodies ( also known as Changelings ) would be taken down a shallow cove to begin their transformation from land - dweller to water - breather . This shallow cove was the only safe place the Ceremony could take place . It was covered in a blue - green algae which created oxygen through for the Changelings to breathe . This process could take weeks , making the Changelings vulnerable to attacks from Yavin 8 ' s predators . Thus , they were guarded by their fellow Melodies who had not changed . During the ceremony , a Changeling ' s legs would grow together into a single finned tail , and they would also grow gills for breathing underwater . When this change had completed , making them Elders , the Melodie would retreat to deep underground lakes within the mountains where they would live in for the rest of their adult lives . Elders were able to surface for limited amounts of time , which they use to communicate with their young . However , this did not apply to the oldest Melodies , who were not able to surface at all . History . The Melodies originated on the arid , tundra moon of Yavin 8 , one of the gas giant Yavin ' s three habitable moons with the others being Yavin 4 and Yavin 13 . They were an amphibious species that lived in the rivers and lakes of the moon ' s purple mountains . Certain xenobiologist s in later years suspected that the Melodies as well as the native predators on their homeworld may have been products of Sith alchemy . In 3997 BBY , during the Sith Lord Exar Kun ' s reign over the Massassi of Yavin 4 , he imprisoned their children in a spherical dark side device known as the Golden Globe , for the purpose of both controlling the Massassi and to drain the life energies of its trapped captives . The desperate Massassi parents came to Yavin 8 to seek help and met the children of the Melodies . The children took them to their Elders , but they could offer no help since they were unable to leave the waters . Thus , the Massassi engraved messages in the rocks and caves of Yavin 8 hoping so that somebody would read them some day and come to their aid . However , these messages were written in the Massassi tongue , which made it difficult for non - speakers to understand the text . Worse , the Massassi were wiped out in 3996 BBY during the Jedi / Republic asssault on the jungle moon . This piece of history would only be preserved in the form of legends by storytellers known as " Keeper of Legends " . Millennia later , sometime in 0 BBY , the Rodian Suz Tanwa discovered the species during a trip in the Yavin system , but did not reveal their existence to the galaxy , fearing that the Galactic Empire would enslave them . In 22 ABY , Master Luke Skywalker ' s Jedi Praxeum on Yavin 4 discovered the Melodies and also allowed a Force - sensitive member of the species named Lyric to study at the Praxeum . Her parents allowed her to go because of the dangerous conditions of their homeworld . Later , when Lyric returned to Yavin 8 to undergo the Changing Ceremony on that same , Jedi trainees Anakin Solo and Tahiri Veila escorted Lyric to her homeworld to undergo the Changing Ceremony . During their trip , they fell under attack by native carnivores including an avril , a reel , a purella , and a number of raiths , though they managed to fight them off . It was also from the Keeper of Legends Aragon that Anakin and Tahiri learned about the existence of the ancient Massassi carvings . They discovered these carvings in a cave . During their trip on Yavin 8 , Anakin and Tahiri also met Sannah , whom they discovered to be Force - sensitive and took her with them during their home trip to Yavin 4 . Later , Sannah assisted them in translating the ancient Massassi carvings . They then learned of the origins of the Golden Globe and how to defeat it . Shortly after the Yuuzhan Vong captured the Jedi Praxeum , the Yuuzhan Vong presumably took the moon . The extragalactic invaders also unleashed deadly Jedi - hunting voxyn on the moon . Among their victims were Lyric . The fate of the species following the Yuuzhan Vong War is currently unknown , although Sannah was present at the Conclave on Zonama Sekot in 30 ABY .
