The events of the game Star Wars Jedi: Fallen Order take place five years after the end of the Clone Wars, in the time period between the previous trilogy of movies and the original trilogy. Cal Kestis, a former Padawan, was in hiding after escaping the massacre of Order 66 that targeted Jedi. He worked as a mechanic in ship dismantling for the Empire on the planet Bracca, where he hid his true identity and abilities. But after being forced to use his Force powers to save his friend Prauf from a dangerous accident at work, he is discovered by the Inquisitors, who are Imperial agents trained to hunt and eliminate remaining Jedi.
After his discovery, Cal finds himself in a race against the Empire and its pursuers, the Inquisitors, in an attempt to find a codex containing a list of children who possess special abilities and Force sensitivity across the galaxy.
The Inquisitors, The Mantis, and Eno Cordova
After saving Bracca from a deadly fall using the Force, Cal is almost immediately discovered by two Inquisitors: The Second Sister and The Ninth Sister. These Inquisitors, trained by Darth Vader himself, are Force users tasked with tracking down any Jedi who survived Order 66. Cal manages to confront the Inquisitors and the squad of Stormtroopers accompanying them, and eventually he is rescued by Cere Junda and Greez Dritus aboard The Mantis. Cere is a former Jedi on a mission to retrieve the Jedi Holocron created by her mentor Eno Cordova.
Zeffo, Kashyyyk, and the True Identity of the Second Sister
The second part of the game is a kind of cat-and-mouse chase where Cal and his companions are led from planet to planet in search of the key that will open the vault. On Zeffo, Cal learns about its ancient inhabitants and their connection to Kashyyk, the home of the Wookies. The team then travels to Kashyyk and becomes involved in a battle between the Resistance, led by Saw Gerrera from the movie Rogue One, and the Empire, which oppresses the Wookies.
Cal learns that Tarfull, a Wookie, was in contact with Cordova and may know how to access the vault. However, after failing to find Tarfull, Cal returns to Zeffo.
There, Cal once again faces The Second Sister who reveals herself to be Trilla, a former Padawan of Cere. During the Clone Wars, Cere left Trilla with a group of younglings, and Trilla was captured by the Empire, where she was tortured and turned into the vengeful Second Sister. Cal narrowly escapes Trilla, but he is captured by a bounty hunter and forced to fight in an arena. He is rescued by The Mantis crew, and by chance, they receive a tip indicating the location of Tarfull. The crew returns to Kashyyk to meet Tarfull.
The Origin Tree, Nightsisters of Dathomir, and Taron Malicos
Tarfull instructs Cal to seek answers in The Origin Tree in the hazardous Shadowlands of Kashyyk. There, Cal discovers a recording by Cordova explaining that the key, known as the Astrium, can be found on a planet called Dathomir. Before he can escape the Shadowlands, Cal must fight and kill The Ninth Sister.
