Leading off from the great hall at the front of the complex was a small balcony that overlooked the nearby lake . History . The Wren Stronghold was the ancestral home of Clan Wren , a legendary family of Mandalorian warriors . During the reign of the Galactic Empire , the stronghold acted as the clan ' s seat of power , and was the residence of the clan ' s leader , Ursa Wren , her son Tristan , and several other members of Clan Wren . In the year 2 BBY , Ursa ' s estranged daughter , Sabine Wren , journeyed to the Wren Stronghold with a group of friends — including the Jedi Kanan Jarrus and Ezra Bridger — in an effort to recruit her clan to the growing rebellion against the Empire . Despite initial hostilities , Sabine and her allies were welcomed into the complex by Ursa Wren , though the Jedi were forced to relinquish their lightsaber s before entering the Mandalorians ' home . While Sabine attempted to negotiate an alliance with her mother , even gifting her ownership of the Darksaber — a longstanding icon of Mandalorian authority she had recently reclaimed from the former Sith Lord Darth Maul — Ursa chose to instead to offer the Jedi to the Empire in exchange for amnesty for both her daughter and Clan Wren , contacting the Imperial Viceroy of Mandalore in secret . Soon after , Viceroy Gar Saxon arrived at the Wren Stronghold with a cadre of Imperial Super Commando s , and it was there that the Empire ' s puppet ruler revealed his intentions to betray Ursa , and kill Clan Wren along with the Jedi . Fighting quickly broke out in the great hall between the Imperial - aligned super commando s and the forces of a Jedi - backed Clan Wren , eventually leading to the deaths of numerous super commandos , while Saxon and Sabine Wren engaged each other in a bout of single combat that spilled out onto the nearby frozen lake . Sabine emerged victorious , though it was Ursa who ultimately killed Saxon , firing on the Imperial governor when he attempted to shoot Sabine in the back after she chose to spare his life . Though the Jedi later departed Krownest , Sabine chose to remain with her clan at the Wren Stronghold , to continue the Mandalorians ' fight against the Empire . With the death of Gar Saxon , civil war between Clans Wren and Saxon soon broke out . During the Empire ' s devastating assault on the rebellion ' s base of operations on Atollon , Ezra Bridger returned 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 of the hostilities between Clan Wren and the Imperial - aligned Clan Saxon . Though their forces were spread thin , Ursa Wren chose to allow her daughter Sabine and a group of Wren volunteers to depart Krownest with Bridger in order to reinforce the besieged rebels on Atollon . The Mandalorian volunteers arrived in the Atollon system not long after , and it was 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 .
