Mission to Dathomir ( Galactic Civil War ) The Mission to Dathomir was an operation carried out during the Galactic Civil War . Prelude . With the Galactic Empire on the run , X2 and the rest of Grey Squadron set out to the planet Dathomir with the stated goal of investigating the Imperial prison on the world . Privately , however , X2 — who was still growing acclimated to his ability to use the Force — acknowledged to his unit that his aim was to pursue his genetic brother X1 , whom he sensed was involved in something untoward within the walls of the facility . The Mission . Grey Squadron was forced to infiltrate the prison by speeder bike through the dense foliage of the surrounding jungle . On reaching the outer gates , X2 and Shara made a surprising discovery : a contingent of lightsaber - wielding Nightsisters , fighting against stormtroopers within the outpost . Realizing the tactical advantage this presented , X2 and Shara split from the rest of Grey Squadron and pushed deeper into the grounds of the outpost . They quickly reunited with their allies at the entrance to the main building , at which point X2 began to sense something resonating powerfully with the dark side inside . Against Shara ' s wishes , he continued into the facility alone . Within the bowels of the prison , X2 encountered the source of the disturbance : an enormous rancor , being riden by the leader of the Nightsister assault . Calling on the Force for aid , X2 repeatedly used Force push on nearby rubble to knock the beast off balance , finishing it off with judicious use of his lightsaber . Once the rancor fell , the Nightsister attacked X2 on foot , but the Force - sensitive clone easily bested her in a duel . The disturbance quelled , X2 and a several of his squadmembers forged their way further into the prison ' s depths . After fending off several more Imperial ambushes , the group finally discovered X1 ' s secret : a cloning facility , complete with cloning tank s filled with what appeared to be early - stage Wookiee clones . Unfortunately for Grey Squadron , X1 was not in the facility ; however , X2 soon located his brother ' s private office in an adjoining room , and with Shara ' s assistance the unit was able to obtain a complete copy of his personal files . Upon returning to their ships , X2 and Shara were greeted by a grim sight : an Imperial saboteur had managed to slip detpacks into several of them , resulting in the destruction of numerous X - wings and the loss of many members of Grey Squadron . As X2 attempted to console one of the dying men , the remaining soldiers brought the captured Imperial before their distraught commander . Overcome with grief , X2 grasped the man with a Force choke and threatened his life , nearly giving in to his anger and falling to the Dark Side . Before he could do so , though , Shara interjected herself , reminding X2 that he must not follow his brother ' s path of vengeance . Chastened by his brush with the Dark Side , X2 let the humbled Imperial go , ordering his squadron to launch what ships were left and flee the planet . In space , the survivors encountered an Imperial Star Destroyer . Unable to make their escape , X2 ordered the remnants of his squadron to attack the vessel , vowing never to run from the Imperials again . During the subsequent fight X2 successfully maneuvered his X - wing through numerous waves of TIE fighters , ultimately destroying the capital ship ' s bridge with several well - placed shots . The resulting explosion then detonated the rest of the Destroyer . Aftermath . By mining the information gleaned from X1 ' s personal data , X2 was able to discover the location of his brother ' s stronghold on the planet Mustafar . Though upset by the events on Dathomir , he vowed to find the resolve to finish the fight with his brother once and for all .
