Raid on the Armand Isard Correctional Facility A raid was attempted in 43 . 5 ABY by rogue Jedi Seff Hellin to free Jedi Knight Valin Horn from the Armand Isard Correctional Facility , a Galactic Alliance prison . The two Jedi were affected by the same psychosis — an illness which caused the affected being to believe that everyone they knew had been replaced by impostors except for other beings that suffered from the disease . Hellin hoped to free Horn , who had been encased in carbonite and placed in the prison . The Galactic Alliance hoped to capture Hellin , while Darkmeld — a covert organization formed by Knight Jaina Solo to counter Chief of State Natasi Daala ' s efforts to weaken the Jedi Order — hoped to capture the Jedi as well , in order to study the disease . As his raid began , Hellin was attacked by two Darkmeld members — Imperial Remnant Head of State Jagged Fel and bounty hunter Tahiri Veila . He managed to defeat them , but the two attacked again , and Hellin was forced to abandon his goal . As he left the prison , Hellin was caught by Galactic Alliance bounty hunters Dhidal Nyz and Zilaash Kuh , who were serving in Daala ' s special - missions force . Solo , however , seized him from the bounty hunters , and loaded him into a speeder piloted by Darkmeld affiliate Mirax Terrik Horn , Valin ' s mother . A speeder chase ensued , and the bounty hunters and several security speeders pursued them , but Darkmeld managed to shake off all of their pursuers . Hellin was taken to the Jedi Temple on Coruscant , where he was to be studied in secret by Mon Calamari Jedi healer Cilghal . Prelude . In 43 . 5 ABY , Jedi Knight Valin Horn suffered a psychotic breakdown , which caused him to believe that everyone he knew — except for other beings suffering from the same disease — had been replaced by impostors . He dueled his father , Jedi Master Corran Horn , and attempted to flee , but was stopped by his family and placed in the Jedi Temple . Horn escaped later that night , but after a destructive rampage he was finally captured and placed in the Mon Mothma Memorial Medical Center . After Jedi Grand Master Luke Skywalker ' s trial and exile for failing to prevent his nephew Jacen Solo ' s descent to the dark side of the Force , Horn was moved back to the Jedi Temple , but he was eventually taken by the Galactic Alliance — who didn ' t trust the Jedi to have custody of Valin Horn — frozen in carbonite , and placed in the Armand Isard Correctional Facility , a prison on Coruscant . Rogue Jedi Seff Hellin , who suffered from the same disease , felt compelled to free Horn , as he believed that Horn was the only being he knew that had not been replaced by an impostor . Hellin was spotted outside the prison by former Jedi Knight and Sith apprentice Tahiri Veila , who — in the years since the Second Galactic Civil War — had become a bounty hunter . She was also a member of Darkmeld , a secret organization formed by Jedi Knight Jaina Solo to counter Galactic Alliance Chief of State Natasi Daala ' s efforts to undermine the Jedi Order . Veila informed Solo of the sighting , and they instantly realized that Hellin ' s intention was to break Horn free . They also realized that if they could capture Hellin , they would be able to study the disease , and hopefully develop a cure for it . Hellin created an intricate plan to enter and exit the prison undetected . As a last - minute addition , Solo and Imperial Remnant Head of State Jagged Fel decided to include Mirax Terrik Horn , Valin ' s mother , to their group of conspirators in order to make use of her contacts , skills , and funds . Terrik Horn would have to keep the group ' s existence hidden from her husband , Corran Horn , because the Jedi Masters were not supposed to know of the organization so that — if they were ever questioned by the Galactic Alliance — they could answer truthfully that they knew nothing about Darkmeld . The raid . First confrontation . Hellin burned a hole in the permacrete above a riot raid tunnel outside the prison . The tunnel had two points of access : a law enforcement station and the prison , but the side that was connected to the prison could not be opened . A few days later , Hellin put his plan to free Horn into motion . He went into the tunnel , where he was intercepted by Veila and Fel . Hellin believed Veila to be an impostor , and because of Fel ' s distinctive armor , Hellin thought Fel was a Mandalorian . Hellin attacked them , sending Fel flying backwards with the Force . Hellin and Veila began a lightsaber duel , and Fel stood and shot a stun bolt at Hellin , who deflected the shot into Veila ' s leg . Next , Hellin turned and ran for a blast door that led into the prison and threw a thermal detonator at Veila . Fel picked up Veila and took off running down the tunnel . Hellin Force - pushed the detonator , keeping it rolling after them . When Fel and Veila were far enough away that Hellin believed the blast would not kill them — he had not come to kill imposters , merely to free Horn — Hellin triggered the detonator . Hellin knew that the blast would make the prison guards think that there had been a fuel explosion outside the prison , or that someone was trying to break free ; so his entry would — at least , temporarily — remain a secret . Hellin then began to melt through the blast door with his lightsaber . Fel ' s Mandalorian armor protected him and Veila from the blast , and Darkmeld member and former Intelligence agent Winter Celchu called in to check on them . Fel informed her of the situation , and told Celchu to call the rest of Darkmeld to the prison . Escape . As Hellin neared his goal , he was confronted by three security guards in a turbolift . He quickly incapacitated them and moved on , fuzzing holocams with the Force as he passed them . Hellin reached the room in which Horn was being kept , and began to melt his way through the blast door with his lightsaber . Veila , however , was not far behind , and reached the corridor outside the room . Veila began jumping up and down in front of one of the holocams in an attempt to draw all of the security guards to the area . Hellin quickly made it through the blast door and found the carbonite slab which held Valin Horn , but when he attempted to release Horn , an error code came up , setting off an alarm . Fel , whom Hellin still believed to be a Mandalorian , came through the door , and Hellin slashed at him with his lightsaber . Fel caught the blow on his beskar crushgaunts , and Hellin continued the attack , but failed to land a blow on anything but the impenetrable armor . Veila entered the room as well , and as he realized that he would not be able to fight off his combatants " and " be able to free Horn , Hellin Force - threw the slab of carbonite containing Valin at Fel and Veila . Veila dodged it , but Fel was not quite quick enough to get out of the way , and he was hit by the slab and knocked aside . Hellin then ran out of the room , leaving the carbonite slab in the doorway to block the exit behind him . He ran down the corridor to the turbolift shaft and jumped blindly in , dropping a few meters . Luckily for Hellin , the lift was above him , and it slowed to a halt at the corridor which he had just left behind . Several security guards looking for Hellin took to the corridor , slowing down Fel and Veila ' s pursuit . Hellin continued out through his escape route , returning to the tunnel which he had used to enter the prison , when — as he passed by the place where his thermal detonator had exploded — he was cut off by more security troopers . He Force - flung the debris created by the detonator blast at the troopers and charged them , quickly incapacitating them . He then took a blaster rifle from one and a pistol from another . As he made for his escape , Celchu attempted to cut Hellin off , and Hellin quickly shot her with a stun bolt from the rifle . Sensing the presences of many security guards closing in around him , Hellin made a break for a shaft to the surface . Capture . Outside the prison , Terrik Horn arrived in a speeder she had stolen from outside her family ' s suite . She spotted Hellin escaping and flew towards him , but was sideswiped by a cargo hauler piloted by bounty hunter Zilaash Kuh , who was working for Natasi Daala ' s special - missions force . Kuh ' s Quarren partner , inventor and bounty hunter Dhidal Nyz , fired an electric net at Hellin , who attempted to dodge the shot . The net , however , was too large . It wrapped about Hellin and immobilized him , sending paralyzing electrical surges through his body every few seconds . The connecting cable from the net to the gun went taut , and Hellin was yanked into the air behind the moving cargo hauler . Solo arrived on the scene , having managed just minutes earlier to get away from Dab Hantaq , her Jedi supervisor — an agent that was tasked to keep track of a Jedi — and witnessed the bounty hunters ' capture of Hellin . She contacted Terrik Horn — who was coming back around in her speeder — and told her to go after Hellin , who was being dragged along through the air . The cargo hauler passed over Solo , and she threw her lightsaber at the cable connecting the net to the gun and severed it . Hellin fell from the sky , still paralyzed by the electric net , and Solo slowed his fall with the Force , letting him hit the ground just hard enough to incapacitate him . Solo knocked Hellin out with a swift blow to his head with her lightsaber hilt . Terrik Horn quickly landed the speeder beside Solo , who lifted Hellin aboard and climbed in . The bounty hunters came around in pursuit , and four of the prison security ' s speeders took off after them . Not far behind , Veila and Fel — carrying with them the unconscious Celchu — quickly stole a speeder and joined the chase as well . Speeder chase . Five security speeders — one piloted by Veila — and the cargo hauler now followed Terrik Horn and Solo . Terrik Horn took the speeder into a tunnel used for maintenance and waste haulers , while Veila quickly maneuvered past two of the security speeders , passing just above the second one so that her speeder ' s repulsor wash knocked the security speeder into the wall . The security speeder crashed to the tunnel surface , and Veila piloted up underneath the bounty hunters ' cargo hauler . Fel — fighting the hauler ' s repulsor wash — slowly stood up and began destroying servos and repulsor nozzles with his crushgaunts . At last , he found an auxiliary energy cell , which exploded as he squeezed it , peppering him with shrapnel . Smoke poured from the area , and the cargo hauler slowed , falling behind Veila ' s speeder . Meanwhile , in the stolen speeder , Solo injected Hellin with a sedative . Turning back to the nearest pursuing security speeder , Solo Force - pushed it sideways into the tunnel wall , holding it there until the pilot was forced to decelerate and drop to the ground in order to keep control of the vehicle . She repeated this process twice more , until the only speeder remaining was that of Veila and Fel . Solo guided the group out of the maintenance tunnels to a small niche off of a major thoroughfare , where they parked the speeders . Aftermath . After they parked , Celchu removed all forensic evidence from the two speeders so that they could not be traced back to any of them . Fel was returned to the Imperial Remnant embassy , while Veila , Terrik Horn , and Celchu met up with Tekli — a Chadra - Fan Jedi healer and Darkmeld affiliate — back at the speeder hangar of the Jedi Temple , where nearby Jedi Masters would be less likely to sense them . They met up with Solo , who had checked in with Hantaq , and was free of the supervisor once more . They took a turbolift to the second medical level , where Tekli opened up a special chamber which only she and fellow healer Master Cilghal were authorized to enter , and Tekli strapped Hellin to a bed inside . The next day , the raid was featured in the news . Suspicion fell upon the Jedi Order , but there was no hard evidence of the Jedi ' s involvement . Galactic Alliance Security forces , under the command of Captain Oric Harfard , arrived at the temple to take Hellin into custody , but since Solo had kept Darkmeld ' s actions secret from the Jedi Masters , acting Grand Master Kenth Hamner told them truthfully that he did not know where Hellin was . Terrik Horn and the non - Jedi members of Darkmeld also escaped scrutiny , as the only being who had been close enough to recognize any of them during the raid was Seff Hellin . Later , Hantaq revealed to Solo that he had guessed that she had taken part in the raid , but had no proof , and so planned to do nothing about it . Solo returned to the room where Hellin was hidden and found Cilghal inside . The Mon Calamari Jedi Master decided to help them run tests on Hellin in order to find out more about the disease from which he and Horn suffered . Behind the scenes . The raid was created by author Aaron Allston for " " , the first novel in the 9 - part " " series , released on March 24 , 2009 .
