Sleheyron / Legends Sleheyron was a planet in Hutt Space . Although it was based on slave trade , its powerful economy made Sleheyron one of the most important Hutt worlds . Description . Sleheyron was a trade world in the Outer Rim portion of Hutt Space . The planet sat at the intersection of the " Pabol Hutta " and " Pabol Sleheyron " hyperlane s . Sleheyron was a volcanic world where the few remaining wilderness were uninhabitable , made of jagged spires of basalt slag . Most of the planet was covered of urban areas , including numerous industrial areas , spaceports and refinery districts . Sleheyron economic muscle was second only to Nar Shaddaa , as was the level of intrigue that occurred there . Most of this economy was based on slave trade and on the refinement of tibanna gas in starship fuel . History . During the Pre - Republic era , Sleheyron was originally a world of the Rakata Empire . The planet was explored and colonized by the Hutts between 27 , 500 and 25 , 000 BBY , before the formation of the Galactic Republic . Sleheyron joined the Hutt Empire and stayed in Hutt control for most of its history . However , Sleheyron was not explored by Republic explorers until the period between 15 , 000 and 8000 BBY . By 25 , 100 BBY , Sleheyron marked the boundaries of the Hutts ' true dominion . Xim the Despot tried to take the planet in order to make it his ninth Throne . In the 25th year of his rule , Xim launched a two - pronged strike at Sleheyron and Ko Vari but was he successfully repelled by the Hutts . This defeat started the Hutt – Xim conflict that finally lead to the fall of Xim ' s empire . By this time , Sleheyron was a treasure world into which only the most trusted slaves were allowed . Several years before the Jedi Civil War , Yuthura Ban was sold into slavery at a young age to Omeesh the Hutt , a Hutt slaver who tortured his slaves regularly . Yuthura Ban eventually entered her master ' s bedchamber and stabbed the sleeping Hutt to death before leaving the planet and join the Jedi Order . Following the Mandalorian Wars , Bochaba the Hutt became a prominent presence on Sleheyron , thanks in no small part to the assassination protocols of HK - 47 . In fact , the assassin droid slaughtered 322 of Bochaba ' s " meatbag " enemies in a single year for his master , including two Hutt households . Later , HK - 47 would claim that some of his finest work was completed on this world . In the end , however , the Hutt was slaughtered in a particularly gruesome manner by the Exchange . In the time following the Jedi Civil War , the planet ' s fuel reserves , one of the largest caches in the Outer Rim , were owned by Vogga the Hutt . After the destruction of the Peragus Mining Facility in 3951 BBY , Vogga was influenced by the Jedi Exile regarding the shipment of Sleheyron fuel to Citadel Station , on Telos IV . In his early days , Ziro the Hutt worked as a loan shark on the planet before moving his operations to Coruscant . Ziro had also gotten golden tattoos from his homeworld . During the Galactic Civil War , Thakba Besadii Diori , a minor Hutt crime lord , operated from Sleheyron where he resided in a mansion in the company of his Devaronian majordomo and a group of of Gamorrean guards . Sleheyron was captured by the invader during the Yuuzhan Vong War but it was unknown what the Yuuzhan Vong did to the planet . The Hutts would not comment on its state , nor would they allow outsiders access to the planet . A decade later , the world and the entire Hutt Space joined the Confederation against the Galactic Alliance during the Second Galactic Civil War . Behind the scenes . Sleheyron was originally planned to be included in " " as one of the planets where the player would discover ancient Star Map s , but was cut from the final release . Most of the information here comes from interviews ( see External links ) , and so their canon icity may be disputed . Some screenshots were released by LucasArts before the completion of the game and were still available ( , , , , ) . Among the music files of the game , however , there are two , titled " mus _ area _ slehey " and " mus _ bat _ slehey . " The former served as the background music for the Rakatan mind trap sequence and the latter appeared during fights aboard the Star Forge . The name of both files suggests that they were originally intended to be the music for Sleheyron areas . There was a team called Team Hutt that worked on a restoration of Sleheyron for " Knights of the Old Republic . " The project is seemingly canceled . The team had released some screenshots of the new module before going silent .
