Serroco Serroco , the homeworld of the Stereb species , was a planet in the Ploo sector of the Expansion Region . A muddy world , Serroco was constantly buffeted by ferocious storms and tornado es that often forced the Stereb to retreat to underground shelters and catacombs . The world was dotted by the grand stone Stereb cities and newer settlements populated by Humans from the Galactic Republic . Serroco was a full member of the Republic , and when the galactic government went to war with the Mandalorian warrior clans in 3963 BBY , the planet became a flashpoint in the growing conflict . Admiral Saul Karath , anticipating a Mandalorian advance on the planet , rounded up a sizable battle group to defend Serroco and placed camps among the Stereb cities . Disdainful of the location of the camps and seeing it as a dishonorable approach , the Mandalorians nuclear - bombed the planet directly when their force arrived at Serroco , destroying the cities entirely . One Republic Navy pilot , Carth Onasi , saved many Stereb lives by calling down false tornado warnings and sending them to their underground shelters , which shielded them from the blasts . Life on Serroco continued on despite the devastation of the planet , and a Republic military presence was reestablished there by the time of the Galactic War several centuries later . By the Imperial Period , a small population of Stereb continued to exist on Serroco . Description . Serroco was a muddy , rainy world located in the Serroco system of the Expansion Region ' s Ploo sector . The homeworld of the Stereb species , Serroco had an atmosphere that supported other sentient life forms , such as Humans . Expansive dirt fields could be found on the planet , with patches of trees and other plants . It rained frequently on Serroco , and bigger storms often broke out , with tornado es sometimes posing a threat to the Stereb . The planet had multiple continents and revolved around at least one star . Serroco ' s land appeared green from space , with oceans covering a large part of the planet ' s surface . The Mandalorian nuclear attack on Serroco during the Mandalorian Wars between the Galactic Republic and the Mandalorian warrior clans had a great impact on the planet ' s landscape — the world ' s Stereb cities were destroyed , leaving only glass craters . History . By the time of the Mandalorian Wars , Serroco was a full member of the Galactic Republic , and Human settlers from the Republic had put down roots on one of Serroco ' s nicer continents . The Republic Navy maintained an orbital watchstation above the stormy planet , issuing tornado warnings to the Stereb , who were not adept with the technology themselves . However , some personnel stationed at the watchstation found it to be a boring posting and amused themselves by calling in fake tornado warnings during festivals , sporting events , and other gatherings , a practice that ended when Serroco ' s senator complained . Multiple Jedi were also regularly assigned to the planet — during the Mandalorian Wars , one of the Jedi on Serroco was the Human Meetra Surik . In 3963 BBY , the Mandalorian warrior clans advanced on Serroco from the planet Jebble — anticipating an attack , Admiral Saul Karath assembled Battle Group Serroco and set up a staging area on the planet , with encampments among the Stereb cities . The camps were home to a great number of Republic Navy personnel , in addition to fringer s selling food and other services to the soldiers . Camp Three featured the extremely popular " Little Bivoli " mess ship , which was run by two fugitives : Zayne Carrick , a former Jedi Padawan wanted for the murders of his entire class on Taris , and Marn Hierogryph , a petty criminal believed to be his accomplice . Despite being two of the most wanted beings in the Republic , Carrick and Hierogryph were able to evade notice right under the nose of the Karath and his battle group . Karath and his team thought they were completely ready for the Mandalorians — they figured that the Mandalorians would not dare to attack the Stereb cities directly , for fear of wrecking potential loot . Karath set up a massive cordon of ships surrounding the planet , hoping to stop the Mandalorians dead in their tracks . On the planet below , however , Carrick had a Force vision of the Mandalorians destroying the Stereb cities and annihilating the Republic camps , and he decided that he immediately needed to warn Karath . In a rush , Carrick stowed away on hotshot Republic pilot Carth Onasi ' s ship , the " Deadweight " , convincing Onasi of his seriousness and hitching a ride with him to Karath ' s bridge on the warship " Courageous " . There , Carrick was recognized as the so - called " Jedi killer " and accused of being a Mandalorian spy . His warnings went unheeded . Soon , a Mandalorian force came out of hyperspace at the edge of the system . Disgusted by the Republic ' s " dishonorable " tactic of placing its camps so close to the Stereb cities , the invaders started off the proceedings by firing off nuclear missiles — to Karath ' s surprise , the missiles angled around the Republic ships , heading toward the Serroco camps . As Karath did not expect this to happen , the camps ' missile defense systems were not online , and the planet was left defenseless . Impacts were counted near twenty - seven populated areas . While the Human settlements sustained heavy damage , the Stereb cities were simply gone , turned into glass craters . Furthermore , only eight of the Republic ships on the surface escaped destruction , one of which carried the Jedi Knight Meetra Surik . Before the missiles were launched , Onasi had buzzed down tornado warnings to seventeen Stereb cities , hoping that their underground catacombs could protect them if Carrick ' s vision came true , an endeavor that saved many lives . Serroco was nearly annihilated , its surface covered in massive craters where once had been cities and settlements . The Republic immediately condemned the destruction of Serroco as a tragedy and a horrific crime , and the devastation was not soon forgotten . Republic propagandist " Benegryph Goodvalor " chose " Serroco " as the name of his imaginary warship in transmissions aimed at the Mandalorians , and the planet became the namesake of a real Republic ship by the time of the later Galactic War . " Goodvalor " was actually Marn Hierogryph , who , along with talented Trandoshan cook Slyssk , had narrowly escaped Serroco ' s destruction on a stolen troop transport , inadvertently saving half of a sleeping battalion . The Republic Defense Ministry turned the rescue into a propaganda story , with " Goodvalor " being feted as the " Hero of Serroco . " Life on Serroco still continued , and by the time of the Jedi Civil War several decades after the Mandalorian conflict , Serroco had a leader named Lelin - Dor , who was known as the First Patriarch . During the war , Revan , the Dark Lord of the Sith , had Lelin - Dor assassinated , believing him to be a destabilizing influence . By the time of the Cold War a few centuries later , a Republic military presence had been reestablished on Serroco . In that same time period , archaeologists discovered an intact Stereb shelter left over from the Battle of Serroco , containing many previously - lost Stereb artifacts . During the Imperial Period , thousands of years after the Battle of Serroco , there was still a small enclave of Stereb on the planet . Inhabitants . Serroco was home to the Stereb species , who built the massive stone cities that dotted the planet ' s landscape . By the time of the Mandalorian Wars , however , Serroco had also been settled by Humans from the Republic , who lived on one of the planet ' s nicer continents . The Mandalorians ' impending attack on Serroco also brought a significant population of Republic Navy personnel to the world , led by Admiral Saul Karath . Meant to defend the world from the Mandalorians , the soldiers lived in camps placed among the Stereb cities . There were also fringers , or freelance tradespeople , who also came to the world with the Navy to sell their goods and services . Notable among these beings were Zayne Carrick and Marn Hierogryph , two of the most wanted fugitives in the Republic , who sold food in Camp Three without attracting any notice . Even before the Battle of Serroco , there was a Republic naval presence above the planet , as it fell to the Republic to operate Serroco ' s orbital watchstation and alert the natives of dangerous weather . Bored crewmen often amused themselves by calling in fake tornado warnings , a practice that drew the ire of Serroco ' s senator . Locations . The Stereb built many stone cities across Serroco , with grand pyramidal buildings and large green columns rising from the earth , although they originally lived in underground catacombs , which the Stereb built to escape Serroco ' s vicious storms and were still maintained as shelters during the era of the Mandalorian Wars . The Republic set up its camps amongst the Stereb cities in preparation for the Mandalorian attack . One of these , Camp Three , featured the " Little Bivoli " mess wagon run by Zayne Carrick and Marn Hierogryph . Boasting the talents of the Trandoshan cook Slyssk , the " Little Bivoli " became popular amongst Republic naval personnel who were tired of the food from the commissary . A watchstation was located in Serroco ' s orbit was operated by the Republic Navy to monitor the planet ' s weather . Behind the scenes .
