Jannah (formerly known as TZ-1719) was a supporting character introduced in Star Wars: The Rise of Skywalker. Like Finn, Jannah is a former First Order Stormtrooper who lived on Kef Bir after her defection. Upon meeting Finn and his comrades, Jannah and her group of other defected stormtroopers joined the Resistance in their fight against the Sith Eternal and Darth Sidious.
As a former stormtrooper for the First Order, Jannah had a sense of honor and justice. When ordered to kill a group of innocent civilians, Jannah refused and disgusted with the First Order's cruelty, defected from the remnants of the Galactic Empire.
In 35 ABY, Resistance operative Rey, Finn, Poe Dameron, Chewbacca, BB-8, C-3PO, and D-O arrived on Kef Bir, an ocean moon of Endor, in search of the Emperor's wayfinder. Being informed by Babu Frik about their mission, Jannah agrees to help them. Jannah helped Finn and Dameron fixed the badly crashed Millennium Falcon. While fixing the Falcon, Jannah handed Finn a gadget which Finn recognized as a piece used by the First Order. Realizing that he had a history with the First Order, Jannah revealed she and her whole crew were once stormtrooper who refused to fire on civilians much like what Finn did during the Attack on Tuanul. Jannah explained how it didn't even feel like a decision but more like an instinct to which Finn replied that it was the Force the probably brought him together to her. Shocked by this, Jannah says that Finn says this like it real to which he replies it is. Just then BB-8 interrupted them and told them that Rey was not with them. Leaving the Falcon, Finn realized in horror that Rey had impatiently took one of the sea skiffs and headed to the ruins of the second Death Star. Seeing the danger, Jannah offered Finn another sea skiff to help Rey. Using the sea skiff, Jannah and Finn explored the corridors of the wreckage in search of Rey. Hearing lightsaber clash, they ran out to trench and saw her fighting Supreme Leader Kylo Ren. Trying to interfere Finn called out her name but was pushed back by the Force. As Finn to interfere again, Jannah told him that they couldn't follow them.
Stranded on the ruins, Finn called Poe and told them to come rescue them. Jannah along with Company 77 boarded the Millennium Falcon flew back to the Resistance base on Ajan Kloss where they learned of Leia's passing. Poe was named general of the Resistance. Just then, they were informed that Kijimi has been completely destroyed. With some advice from Lando Calrissian and Finn as his co-general Poe devised a plan to take out the Xyston-class Star Destroyers. As Lando and Chewbacca used the Millennium Falcon rallied up any free worlds to help aid them, Jannah and her crew gathred up their orbaks and boarded the Fortitude and headed to Exegol thanks to Rey using Kylo Ren's wayfinder to transmit the map to the Resistance.
Arriving on Exegol, the Resistance were immediately attacked by the Sith Eternal forces. While the Exegol air team tried to protect the ground team, the Sith fleet's navigation tower suddenly switched off. Know that those were the only way to prevent the Sith Star Destroyers from leaving Exegol, the Resistance opted retreat, however Finn sensed from the Force that the navigation signal was coming from the Resurgent-class Star Destroyer Steadfast. Jannah asked how did he know to which Finn replied a "feeling". Landing on hull of the Steadfast, Jannah, Finn, and the rest of the Resistance team used the orbaks to ride across the the command ship as they were confronted by Sith troopers. Jannah threw and detonator to distract the troopers and give them enough for BB-8 to open the hatch during which she shot down a Sith jet trooper. When BB-8 got the hatch opened, they threw down a bunch of grenade which destroyed the hatch and temporarily shut down the navigation signal.
However when everybody was retreating, Finn realized that the Sith Eternal was planning on reboot the system, Finn decided to stay and destroy the Resurgent Star Destroyer. Jannah decided to stay with and help get the job done. Turning one of the Steadfast's turbolasers on its bridge, Jannah and Finn witnessed the arrival of a citizens' fleet from across the galaxy commanded by Lando to help them, the arrival caused a great turn of tide in the battle. However, down below in the Sith Citadel, Darth Sidious, now fully revived by absorbing Rey and Ben Solo's Force dyad, used a vast amount of Force lighting at the fleet, temporarily disabling them. Rey guided by the spirit of past Jedi used both the Skywalker lightsaber and Leia Organa's lightsaber to destroy the phantom Emperor. With Sidious dead, Jannah and Finn were able to used the turbolaser to destroy the Steadfast, killing Allegiant General Pryde. The Steadfast began falling toward the surface with Jannah and Finn still on it, however they were saved by Lando and Chewbacca on the Millennium Falcon. With the Final Order destroyed and Sidious dead, the Resistance and the galaxy fleet won the battle and retreated back to Ajan Kloss.
Back on Ajan Kloss, the Resistance and their allies celebrated their victory and the defeat of Sidious and the Sith Eternal. Seeing Lando, Jannah sat beside and asked him where he was from to which he replied the Gold system. Turning around, Lando asked Jannah where she was from with the latter saying she did not know. Smiling, Lando decided to help Jannah travel across the galaxy to help find her home.
