Krownest Krownest was an icy world in the Outer Rim Territories ' Mandalore sector , cold and covered in snow . Mountain ous terrain and evergreen forest s comprised much of Krownest ' s frigid landscape , and its atmosphere proved breathable to human s . A planet under Mandalorian governance , Krownest was the ancestral home of Clan Wren , a legendary Mandalorian family whose warriors possessed a stronghold on the snowy world , built along the edge of a frozen lake . Two years before the Battle of Yavin , the Mandalorian rebel Sabine Wren traveled to Krownest with the intent to enlist the aid of Clan Wren against the reigning Galactic Empire . Despite initial hostilities between Sabine and her estranged family , and an attack on the Wrens ' stronghold by a group of Mandalorian super commandos in the employ of the Empire , Sabine and her mother Ursa Wren were able to reconcile after years spent apart . However , during the super commandos ' attack , Ursa had been forced to kill the Imperial governor Gar Saxon in order to save her daughter ' s life , and the resulting civil war that ensued between the Wren and Saxon clans kept the Mandalorians from fully supporting the larger rebellion against the Empire . Even still , Clan Wren sent several warriors and a squadron of Fang starfighters from Krownest to aid the besieged rebels on Atollon during the Empire ' s attack on their hidden base , allowing the insurgents and what remained of their fleet to escape with their lives . Description . A frigid planet , Krownest was located in the Mandalore sector of the galaxy ' s Outer Rim Territories . Krownest was a terrestrial world blanketed in ice and snow , possessing a cold climate and an atmosphere breathable to human s . The planet ' s terrain was largely comprised of mountain ous regions dotted with forests of tall evergreen tree s . A Mandalorian world , Krownest was the ancestral home of Clan Wren , a legendary family of Mandalorian warriors who constructed a fortified stronghold on Krownest along the banks of a frozen lake . The Wrens ' complex , constructed from steel and glass , blended elegantly into the snowy landscape of Krownest . At least one member of Clan Wren monitored traffic around Krownest , and vessels entering the planet ' s airspace would be met either by a cadre of the clan ' s jetpack - equipped soldiers or a squadron of Fang starfighters . History . Conquered by the Mandalorians , Krownest became home to the legendary warriors of of the Mandalorian Wren clan , and acted as the clan ' s seat of power well into the reign of the Galactic Empire . Prior to entering the Imperial Academy on her homeworld of Mandalore , Sabine Wren spent a period of time on Krownest in her youth . Her eventual departure from the snowy world did not come about on good terms , and the young Mandalorian woman subsequently did not return to Krownest for many years after . That finally changed in 2 BBY , when Sabine — along with several members of the nascent rebellion against the Empire — journeyed to Krownest in an attempt to persuade her estranged mother and clan leader , Ursa Wren , to ally her people with the rebels in their fight against the Imperial forces . Though the rebels ' ship was initially forced down to Krownest ' s snowy surface while under fire from Mandalorian troop s , Sabine and her allies were finally given safe passage to meet with her mother at the Wren Stronghold once her identity was confirmed . During the ensuing talks , Mandalorian super commandos loyal to the Empire arrived on Krownest in pursuit of the rebels , led by Imperial Viceroy Gar Saxon . At the Wren Stronghold , Saxon declared Clan Wren guilty of colluding with the rebellion and ordered their executions , leading to a shootout between Saxon ' s super commando s and the forces of Clan Wren . The firefight quickly came down to a duel between Saxon and Sabine Wren , spilling out from the stronghold onto one of Krownest ' s frozen lakes , where Saxon was ultimately defeated and slain . While Sabine ' s rebel allies departed the snowy world in the battle ' s aftermath , she instead chose to remain on Krownest with her mother and clan . Later , during the Empire ' s devastating assault on the rebellion ' s base of operations on Atollon , the young rebel and Jedi - in - training Ezra Bridger fled to Krownest , to once again ask Clan Wren for their aid against the Empire . At the Wren Stronghold , Bridger informed the Mandalorians of the Imperial attack , only to learn that Clan Wren had become embroiled in a civil war with the Imperial - aligned Clan Saxon in the time since Gar Saxon ' s death . Though their forces were spread thin , Ursa Wren chose to allow her daughter Sabine and a group of volunteers from Clan Wren to depart Krownest with Bridger in order to reinforce the besieged rebels on Atollon . The Mandalorian volunteers arrived in the Atollon system soon after , and due to their efforts the Imperial Interdictor vessel positioned over Atollon was ultimately destroyed , allowing numerous rebel ships and personnel to escape the planet and continue the fight against the Empire .
