Gravestone The Gravestone was a massive alien combat frigate that was able to defeat the Eternal Fleet , a fleet of droid - controlled warships that was systematically destroying all life within Wild Space , with its powerful Omnicannon . The Gravestone disappeared after the battle with the fleet , scuttled in the Endless Swamp of the planet Zakuul . Centuries later , it was discovered by the crew of the Outlander , who repaired the starship and used it to escape Zakuul . The Gravestone became the mobile base of the Outlander ' s group prior to the establishment of the Alliance on Odessen . History . Early history . The Gravestone was a combat frigate built by a group of scientists in the planet of Iokath , centuries before the Galactic War between the Sith Empire and the Galactic Republic . The Gravestone ' s powerful Omnicannon was capable of targeting an enemy starship and spreading the damage to other nearby vessels , which proved incredibly useful against the Eternal Fleet — a massive fleet of unstoppable warships controlled by sentient droids that was decimating all life it encountered . In a massive battle , the Gravestone defeated the Eternal Fleet and deactivated it , leaving the ships dormant somewhere in Wild Space . The Gravestone was believed lost , though in actuality its builders scuttled the frigate and set it down in the Endless Swamp of the planet Zakuul , where it remained for centuries . Rediscovery . It was finally rediscovered by Koth Vortena , Lana Beniko , HK - 55 and the Outlander after crashing in the swamp following a rescue mission to free the Outlander from the Spire . The group repaired the vessel and managed to escape Zakuul in the Gravestone , using the Omnicannon to punch a hole in the Eternal Fleet — now under the control of Arcann , Emperor of the Eternal Empire . The Gravestone managed to limp to the nearby shadowport Asylum , where the ship was repaired and Vortena ' s old crew joined the vessel . The droid intelligence SCORPIO joined the Outlander ' s crew in order to speak with the Gravestone ' s central computer , seeing it as an intelligence that rivaled her own ; upon connecting with the ship , she was able to repair and revitalize many of its systems — just in time to use them during the Battle of Asylum , when the Outlander ' s crew escaped the Eternal Fleet ' s blockade and assault upon Asylum . The Gravestone traveled to the planet Odessen , where it remained docked with the Outlander ' s fledgling Alliance constructed base in the cliffs nearby . The Alliance inner circle later took the Gravestone on a mission to seize an Eternal Fleet warship in hopes of using GEMINI Prime to take control of the whole network . The " Gravestone " kept the battlecruiser occupied as a boarding party , composed of the Outlander , Lana , Senya Tirall , SCORPIO and Theron Shan , managed to board the ship . However , the mission went south as the GEMINI captain broadcast a distress signal . After getting the boarding party , sans SCORPIO , along with two pods of prisoners , the " Gravestone " escaped into hyperspace as Arcann ' s flagship and the Eternal Fleet arrived . While in hyperspace , the " Gravestone " received a transmission from SCORPIO , who had faked her destruction and had taken control of most of the Eternal Fleet . The Battle of Odessen . The " Gravestone " later defended Odessen against Arcann after SCORPIO leaked its location . With Theron manning the omnicannon , the " Gravestone " fired two shots that destroyed a portion of Arcann ' s support ships , enabling the Outlander and a strike team to board and disable the Eternal Flagship ' s weapons and shields . The omnicannon soon malfunctioned as SCORPIO attempted to remotely take control of the ship , but was shut out by Koth . Subsequently repairing the omnicannon , the " Gravestone " fired at the Flagship just as the Eternal Fleet grouped together to charge up a powerful energy attack , causing a massive explosion that destroyed the Flagship and the Fleet , saving the Alliance from annihilation . The Invasion of Voss . The " Gravestone " later saw action over the planet Voss , defending the planet from being decimated by the Eternal Fleet , before the arrival of the Sith Empire drove off the enemy . Return to Iokath . The Gravestone later responded to a distress call from a cargo freighter called Ridala , which was under attack by two Eternal Fleet ships . Koth allowed the Ridala to dock aboard the ship , unaware that it secretly contained Empress Vaylin and SCORPIO , who had taken advantage of the Outlander ' s apparent demise on Dromund Kaas to seize the " Gravestone " . Koth managed to remain at large while the rest of his crew were taken captive by Vaylin , and managed to send a distress call to Odessen . With the bridge controls and weapons locked by a special passcode of Koth ' s , preventing Vaylin and SCORPIO from taking control of the ship , the Empress interrogated his second , Len Parvek , who revealed under torture that the passcode was based on Koth ' s war record on the soldiers who died under his command . As the Alliance fleet engaged the Eternal Fleet , the Outlander and Lana Beniko boarded the " Gravestone " to retake the ship . Koth then informed them that he had secretly placed a quantum bomb onboard the ship that would go off if SCORPIO unlocked the bridge control without his secondary passcode . The Outlander and Koth worked to disable three bomb fuses before heading to the bridge , finding the latter ' s crew left alone . A hologram of SCORPIO revealed she knew of the quantum bomb , as she wished to preserve the Gravestone , and that Beniko was fighting Vaylin in the dark sanctum of the ship , where Koth hid the bomb . As the Outlander fought Vaylin , their fight accidentally set the bomb off on a three minute timer . Just as Vaylin had the advantage over her foe , Valkorion directly intervened , activating his daughter ' s mental conditioning with the phrase , " Kneel before the dragon of Zakuul ] ] , forcing the Empress to retreat . With the bomb about to go off , the Outlander destroyed any nearby power relays , allowing Koth to defuse the bomb . Soon after , Theron Shan brought a small Alliance squad with him aboard the ship . Unfortunately , with the " Gravestone " no longer in danger , SCORPIO , revealed to be operating under her own agenda , seize control of the ship and discovered the location of Iokath , in which she promptly set a course As the Gravestone entered Iokath ' s superstructure , the occupants were soon incapacitated by a planetary energy weapon fired by ARIES , the only sentient droid caretaker of the planet , who then spread both the Outlander and Vaylin ' s crews across the planet to place in impossible " tests " to determine who was worthy of inheriting Iokath . The " Gravestone " was then impounded at a fleet spire along with the Eternal Fleet . Theron repeated attempted to scan for the " Gravestone ' s " location with no success before deciding to scan for his shuttle docked in its hanger . He then remotely piloted his shuttle to the Outlander ' s party ' s location and after dropping their leader off at ARIES ' base , flew to the " Gravestone ' s " location . The " Gravestone " then returned to ARIES base to retrieve the Outlander and managed to escape Iokath before the energy weapon overloaded and flooded the planet with lethal radiation . Upon their return to Odessen , the Alliance got to work upgrading the " Gravestone " with datafiles recovered from Iokath to improve its combat abilities , rendering it inoperative for the time being . The Second Battle of Odessen . The new upgrades were nearly complete when Vaylin led a second assault on Odessen . The Outlander , who had returned after chasing Vaylin to Nathema , defended the " Gravestone " , giving the crew enough time to finish the upgrades so the frigate could join the battle . The Battle of Zakuul . Following Vaylin ' s defeat , The Outlander headed to Zakuul to seize the Eternal Throne . The " Gravestone ' s " omnicannon allowed the strike group to break the blockade around the Spire and land on the surface of the planet . Nathema Conspiracy . Upon the Alliance mission to Nathema , the Gravestone was hijacked by Zildrog and used to destroy the Eternal Fleet . Afterword , it was poised to destroy Odessen , but was thankfully stopped after the Alliance Commander destroyed Zildrog , destroying the " Gravestone " and Eternal Throne in the process .
