Sepan campaign The Sepan campaign was a series of battles that occurred as the Galactic Empire attempted to bring an end to the Sepan Civil War in 3 ABY . The Campaign . Respond to S . O . S . . Building on their momentum after the victory at Hoth in 3 ABY , Admiral Harkov received the assignment to put down the civil war between the Ripoblus and Dimok factions . Admiral Harkov briefed his crew on use of force to make peace in the Sepan system , while Secret Order representatives , ever present aboard Imperial starships , warned key pilot Maarek Stele that conflicting reports of events among the Sepan system did not seem normal — pilots should be wary of anything suspicious . " Victory " - class Star Destroyer " Protector " entered the system just as a Ripoblus convoy came under attack by Dimok marauders . Ripoblus modular conveyor s " Asbo " and " Lambda " - class T - 4a shuttles " Bezil " , " Gamu " , and " Bredis " found themselves under fire from Dimok BTL Y - wing starfighter s , escorted by " Assassin " - class corvette " Falx " , Cargo ferries " Delphine " , " Mangonel " , and MC40a light cruiser " Falaricae " . " Protector " launched two flight groups of TIE / LN starfighter s to drive off the Dimok attackers , while a single group of TIE / sa bombers attacked corvette " Falx " . Imperial TIE fighters quickly began to drive off Dimok raiders with superior firepower . While Dimok and Imperial starfighters clashed , a single fighter inspected the contents of transports " Asbo " , revealing Imperial arms and other munitions . The " Protector ' s " interceptors succeeded in driving off the Dimok attack force , deploying " Delta " - class DX - 9 stormtrooper transport " Epsilon 1 " to disable and capture the vessels for in - depth inspection by Imperial Stormtroopers . As Epsilon 1 successfully disabled the conveyors , a Ripoblus " Delta " - class JV - 7 escort shuttle emerged from hyperspace , heading for " Epsilon 1 " . TIE fighters moved to intercept the shuttles before they could interfere with capture operations . Having driven off the Dimok and capturing stolen Imperial property aboard " Asbo " , Imperial vessels returned to Victory Star Destroyer " Protector " . Intercept attack . As retaliation for the raid on their convoy , Ripoblus forces launched an attack against a Dimok space station . The initial Ripoblus attack consisted of two " Assassin " - class corvettes and six " Gamma " - class ATR - 6 assault transports . The Dimok XQ1 Platform " Youst " only had a handful of Z - 95 Headhunters and escort shuttles and soon its defenses were exhausted . Aboard " Protector " , Imperial leaders insisted control be established swiftly , fearing that the Sepan conflict could begin spilling over into neighboring star systems . Pilots received orders to destroy the Ripoblus raiders , but only sufficient numbers to drive off the attack . Secret Order agents again tasked select Maarek Stele to inspect the station , dubious of the station ' s purpose , furthermore to be observant of other strange activity . Hoping to send a concise message , the " Protector " deployed TIE fighters and bombers to thwart the Ripoblus strike , beginning with making an example out of one of the " Assassin " - class corvettes . Midway in the battle , the Ripoblus Nebulon - B2 frigate " Dromon " exited hyperspace and attacked " Protector " . The frigate , however , was outmatched and destroyed by the Victory Destroyer and TIE bombers who turned back to deal with the new threat . Bombers from " Beta " group succeeded in destroying Ripoblus corvette " Galliot " and several assault transports , causing the Ripoblus to withdraw . As Ripoblus forces began to leave the system , TIE bomber " Beta 2 " inspected the nearby Station and cargo containers , proving Ripoblus claims that Station " Youst " conducted weapons research . " Protector " launched two transports from " Epsilon " group to capture weapons found among the station , aided by TIE bombers " Beta " . Following the successful capture operations , Imperial shuttle " Toten " emerged from " Protector ' s " hangar , carrying the First Officer , departing for an unknown location . Rescue war refugees . Following the Ripoblus raid on Station " Youst " , Admiral Harkov ' s forces received a request from Ripoblus refugees seeking asylum from the Sepan conflict . Chiefly scientists , the refugees had hijacked an IPV - 1 System Patrol Craft and a couple of " Lambda " - class shuttles , yet lacking hyperdrive , could not flee the system aboard the patrol craft . " Protector " accepted the refugees ' request , deploying TIE fighters and interceptors to cover docking operations between the " Protector " and patrol craft " Glas " , while expecting reprisals from the Ripoblus government . As expected , the " Protector " arrived near the Glas as Ripoblus shuttles and Y - wings began an assault to foil the refugee escape into Imperial hands . Imperial TIE interceptors easily bested the initial attack force , only to discover additional waves of Ripoblus and even Dimok forces attempting to stop the docking operation . With secure space around the " Protector " , patrol craft " Glas " succeeded in transferring refugees over to the " Protector " . Refugee shuttles " Nazaar 1 & 2 " took sanctuary inside the " Protector ' s " hangar , but not before a final raid of Ripoblus escort shuttles arrived . Imperial fighters promptly put down the futile attempt by the Dimok raiders , aided by the decimating support of the " Protector ' s " turbolasers . Capture enemies . With the refugees safely aboard the " Protector " , Admiral Harkov could return to pacifying the Sepan system . Imperial Intelligence discovered plans of a deep space rendezvous between Ripoblus and Dimok leaders near Sepan 8 . Harkov ' s forces organized a special operations mission to intercept and capture the leaders of both sides in attempt to expedite peace . Two transports from " Omega " , escorted by eight " Alpha " - class Xg - 1 Star Wing assault gunboats , entered the system where the meeting was taking place . Gunboats disabled Dimok shuttle " Keydon " , and Ripoblus shuttle " Phantele " . As transports " Omega " proceeded to seize the occupants of the shuttles , gunboats clashed against Z - 95 Headhunters and escort shuttles deployed from Ripoblus EF76 Nebulon - B escort frigate " Shemsher " , Dimok Nebulon - B2 frigate " Manus Ferre " , and Calamari Cruiser " Falaricae " . Gunboats succeeded at repressing enemy fire from " Omega 1 & 2 " while docking completed . Transports " Omega " slipped into hyperspace with cargo aboard , leaving intercepting forces to Imperial gunboats . During the hostilities , Cargo Ferries " Godendag " and " Glaive " arrived , accompanied by " Assassin " - class corvette " Runka " . Gunboats " Mu " disengaged from the dogfight to inspect these new craft , discovering Imperial arms within . This confirmed suspicious of the Secret Order , who previously suggested Dimok and Ripoblus forces lacked industrial capabilities to arm themselves to the visible degree they had . Gunboats " Mu " succeeded in destroying Ferries " Glaive " and " Godendag " before returning to the " Protector " . Following the raid , Imperial forces discovered the occupants of the Dimok and Ripoblus shuttles to be merely the children of conflict leaders . Further interrogation revealed that conflict leaders intended to use their children as a cynical attempt to keep either side in adherence to a new treaty . Dimok and Ripoblus leaders designed this treaty to stop hostilities among one another in the hopes to drive out the Imperial presence . Guard the resupply . Operational losses required replacements for Victory Star Destroyer " Protector ' s " TIE Squadrons . The accent depleted forces ; " Ton - Falk " - class escort carrier " Tropsobor " rendezvoused with the " Protector " to drop off four groups of the new TIE Avenger starfighters . During such an exposed operation , Imperial forces expected a combined attack from Dimok and Ripoblus forces . The " Protector ' s " standard patrol of TIE fighters encountered a dual pronged attack just moments after " Tropsobor " began ferrying the new Avengers to " Protector ' s " hangar . The Dimok " Assassin " - class corvette " Long Tan " and Mon Calamari Light Cruiser " Ben Het " arrived and immediatedly launched Z - 95 Headhunters to attack the TIE Avengers , while wave after wave of Y - wings exited hyperspace to launch proton torpedos against the " Tropsobor " . TIE Interceptors " Gamma " and TIE fighters " Alpha " had the difficult task of escorting the TIE Avengers and protecting " Tropsobor " , beating off the attacking Z - 95s and then holding back the relentless assault from the Y - wings . " Protector " also initiated a counter - attack as TIE Bombers from " Beta " group began torpedo runs against " Ben Het " . Maarek Stele , despite piloting a standard TIE Fighter , was instrumental in ensuring the safety of the Avengers and " Tropsobor " , and even aided in the destruction of " Ben Het " . Reportedly , all of the TIE Avengers arrived safely aboard " Protector " , thanks to their speed and deflector shields . Mission complete , carrier " Tropsobor " entered hyperspace . The Ripoblus conducted an attack of their own , uncoordinated with the Dimoks , as " Delta " - class JV - 7 escort shuttles targeted " Protector " . However , lacking warheads and arriving too late to disrupt the completely ferry mission , the escort shuttles were destroyed by " Protector ' s " turbolasers and TIEs from Alpha and Gamma squadrons . Not soon after , Imperial shuttle " Omlaut " arrived from hyperspace . TIE fighter " Alpha 2 " , piloted by Stele , performed a passive scan of the shuttle , revealing the presence of a Rebel Leader aboard , headed toward Victory Star Destroyer " Protector " . With information gained from the re - supply mission , members of the Secret Order concluded that with increasing supply shortages aboard the Protector , and various Imperial weapons being found among Dimok and Ripoblus cargo holds , Admiral Harkov must be running a black market operation in the Sepan system , specifically selling to both sides of the Sepan conflict . Secret Order agents rapidly took information about these discrepancies to the attention of Lord Darth Vader himself . End of the war . Soon after receiving the new TIE Avengers , Admiral Harkov addressed leaders of the Sepan system . Harkov declared the end of the Sepan Civil War , demanding that both sides lay down their arms . Harkov continued , suggesting that peace and increase prosperity will be achieved by cooperating with the Empire , moreover reparations of their planets had already begun . While temporarily suppressed by the Empire , under a negotiated peace treaty between the Ripoblus and the Dimok , the war would once again flare up during the Second Galactic Civil War . Behind the scenes . The Sepan Campaign known as Tour of Duty 2 or Battle 2 " The Sepan Civil War " in " " . Maarek Stele receives promotions to lieutenant and captain during the course of this campaign . Gamespot ' s Jason Ocampo listed Battle 2 Mission 5 as his favorite level in " TIE Fighter " .
