Tristan Wren was the son of Alrich Wren , Count ess Ursa Wren and the younger brother of Sabine Wren . After Sabine abandoned the Imperial Academy on Mandalore and joined the rebellion , Clan Wren ' s loyalties to the Empire were called into question .

His father was also kept a hostage of Saxon on Mandalore to guarantee his family ' s loyalty . Tristan lived with his mother Ursa on the planet Krownest . Reunion with Sabine . In 2 BBY , Tristan led a patrol of Clan Wren warriors which intercepted and shot down Sabine ' s shuttle " Phantom II " . Sabine and her rebel comrades Kanan Jarrus , Ezra Bridger , Fenn Rau , and Chopper were traveling on a mission to Krownest to solicit Clan Wren ' s support for the rebellion . After the " Phantom II " crashed on the snow , Tristan and his comrades confronted Sabine , Kanan , and Ezra . Tristan initially did not recognize Sabine because she was wearing her Mandalorian helmet . When Ezra ignited his green lightsaber , Tristan and his companions opened fire , leading to a brief firefight . When he heard Sabine ' s voice , Tristan ordered a cease fire and removed his helmet . While Tristan was friendly towards Sabine and her rebel friends and agreed to lead them to the Wren Stronghold , he warned Sabine that he could not vouch for their mother ' s hospitality . During the journey , Sabine confronted Tristan about his Imperial Super Commando armor . Tristan warned that she should not have returned since her family still regarded her as a traitor . Upon arriving at the Wren Stronghold , Ursa ordered Sabine ' s incarceration but Sabine managed to convince her mother to grant her and her friends an audience by showing the Darksaber , an important symbol of House Vizsla ; of which Clan Wren was a member . Ursa reluctantly acceded to her daughter ' s request but ordered the rebels to surrender their weapons . Inside the throne room , Tristan and his warriors maintained a vigil as Ursa appraised her daughter of their family ' s circumstances . Tristan and his mother regarded the Journeyman Protector s and their leader Fenn Rau as traitors and sought to justify the Protectors ' execution by Saxon . After Ursa and Sabine left for a private meeting , the Jedi Rebels Ezra tried to make light conversation with Tristan . However , Kanan insisted on handling the negotiations and told Tristan that he desired an audience with Countess Ursa . Tristan later informed his mother and sister that Gar Saxon was requesting a hologram conversation with Ursa . Still on good terms with Sabine , Tristan invited her for a sparring session in the training room . While sparring with metal rods , Sabine thanked Tristan for practicing with her . When Sabine asked if he thought she was a traitor , Tristan told her he did not think so but that the other clans viewed them with suspicion . Tristan vowed to help restore his family ' s standing to protect their father . Tristan then informed his sister of their mother ' s plan to trade the rebels and the Darksaber with Saxon in return for their safety . Tristan followed Sabine to he throne room where they discovered Gar Saxon and his Super Commandos taking the Jedi rebels and the Darksaber into their custody . When Sabine protested , Tristan told her that it was for the best . When Ursa demanded that Saxon uphold his side of the bargain , Saxon ordered his men to exterminate Clan Wren for " colluding " with rebels . Tristan protested but Saxon gave him the choice of standing by him or dying with his family . Tristan chose his family and pointed his blaster at Saxon .

Following some discussion , Ursa relented and allowed Ezra and Sabine to depart with several volunteers and ships . Tristan accompanied Sabine ' s strike team and took part in a successful assault on an " Interdictor " - class Star Destroyer .

While Sabine and her allies freed Alrich , Tristan and his mother commanded a successful skirmish against Governor Saxon ' s Imperial Super Commandos . With the battle going in Clan Wren ' s favor , Tristan and Ursa were contacted by Sabine , who informed them of their victory . While Ursa was reporting on their victory , Tristan spotted the arrival of a single Imperial reinforcement : a modified All Terrain Defense Pod . This walker was equipped with an Arc Pulse Generator known as the " Duchess " , which was capable of incinerating Mandalorian warriors . The " Duchess " reacted against the beskar alloy inside the armor , incinerating the warriors and leaving behind charred armor . Due to Sabine ' s warning , Tristan and Ursa managed to take shelter and survived the massacre . The two were later rescued by Sabine ' s forces , who evacuated aboard one of Lady Bo - Katan ' s ships . During the journey , Tristan and the others learnt about Sabine ' s role in creating the weapon during her Imperial Academy days . After arriving at Lady Bo - Katan ' s base , Sabine offered to lead an assault to destroy the " Duchess " and the associated data in order to make amends for her wrongs . The weapon and the data was stored aboard Governor Saxon ' s Star Destroyer , which was docking above Sundari . Tristan volunteered to join his sister ' s strike team . During the assault , Tristan and Fenn Rau fought Imperial forces in the hangar bay of Saxon ' s Star Destroyer while Sabine and Bo - Katan destroyed the weapon , causing an explosion which engulfed the Star Destroyer . Meanwhile , the Spectres Ezra , Chopper , and Kanan deleted the data . Tristan and his rebel and Mandalorian comrades escaped the Star Destroyer before it crashed to the ground .
