At first glance, Rogue One doesn’t appear to stray very far from classic Star Wars - it’s the Rebel Alliance’s struggle against the Galactic Empire, revolving specifically around the Death Star. That sounds like the majority of the Star Wars episodes. Stylistic differences aside, the real place Rogue One differentiates itself is in its spotlight on characters that would be considered minor characters or background characters in any other Star Wars movie.

Jyn Erso gets the majority of the focus this time around, featuring a few flashbacks to her life as a child and showing her involvement in the plan to steal the Death Star plans, but a lot of details about the character don’t actually appear on screen. If you liked her and want to know more about her, or if you thought she needed more development and want to know more about her backstory, here’s Everything You Need to Know About Jyn Erso.

15. Felicity Jones Has a Multi-Picture Deal

It’s been clear for a while that there’s not going to be a Rogue Two. The ending of Rogue One was already telegraphed at the start of A New Hope, and now that the movie’s here, we know none of the Rogue One team ever make it off of Scarif. Nonetheless, that doesn’t necessarily mean that Rogue One is the last time any of these characters will appear in the Star Wars universe.

It’s already been revealed that Forest Whittaker will be reviving his role as Saw Gerrera in the second half of season 3 of Star Wars Rebels, and it’s possible a similar story could be told about Jyn. After all, Felicity Jones has a sequel option in her contract.

Still, multi-picture deals are standard fare for most blockbusters, her contract was likely completed before the final script was, and any additional movies don’t necessarily have to be in the Star Wars universe, although her most interesting story has likely already been told with Rogue One.

14. Jyn Was Born in Prison During the Clone Wars

Jyn Erso was born at the height of the Clone Wars on the icy planet of Vallt. Her father, Galen Erso, had been using a facility on the planet to attempt to produce synthetic kyber crystals for Zerpen Industires with the cooperation of the local government. When Vallt eventually abandoned their Republic ties to side with the Separatists, Galen’s refusal to lend his talents toward the Confederate war effort landed him and his pregnant wife, Lyra, in a Vallt prison.

Despite their captivity, Vallt’s prison conditions were fairly comfortable, and Jyn’s birth was even celebrated by the people of Vallt, who considered all births a sacred event. The family was kept separate during captivity, so she only spent a few days of her first 6 months of life with her father, but Orsen Krennic eventually arranged for their release, at which point Galen, Lyra, and Jyn were finally a able to live together in their apartment on Coruscant.

13. She's the Daughter of Scientists

Jyn spent her early years in a very scientifically minded household. Her father, Galen, was one of the galaxy’s greatest polymaths. He devoted most of his life to researching and understanding kyber crystals, establishing himself as the number one expert on the gems that powered the Jedi lightsabers.

As a geologist, Lyra Erso also had an affinity for Kyber crystals, but she also had a strong faith in the Force and held great respect for the spiritual tradition of the crystals. She assisted Galen in his quest to harness the power of the crystals, but always cautioned him of the Jedi’s own reluctance to exploit the crystals themselves.

Galen and Lyra both tried to imbue Jyn with their scientific knowledge and spiritual beliefs in the few years they had together before Orsen Krennic separated them when Jyn was 8. If they had been able to remain in hiding to raise Jyn, one can only wonder what she may have grown up to become.

12. She Was Homeschooled by Lyra

Education is rarely a focus in the Star Wars universe. In A New Hope, luke yearns to attend “the academy,” we see some Jedi training throughout the movies, and the novel Lost Stars details Ciena Ree and Thane Kyrell’s training at the Imperial Academy on Coruscant, which includes some formal education as well, but the Rogue One prequel novel, Catalyst, provides a unique look into the elementary schooling of Jyn Erso when Lyra and Galen decide to homeschool her.

Logic would seem to suggest that this might be a fairly common tradition in the Star Wars universe - it’s also likely that many characters simply aren’t formally schooled at all - but Jyn getting her early education from Galen and Lyra only makes sense considering her upbringing and genious parents. Her schooling is obviously interrupted when Lyra is killed and Galen is forced to the Empire, at which point she receieves a very different education from Saw gerrera - but more on that later.

11. Given the Nickname "Stardust" By Galen Erso

Galen and Jyn were mostly separated for the first several months of Jyn’s life, but the two always shared a special bond, and Galen always called her affectionately by the name “Starust,” after comparing flecks in her eyes to star dust when she was a baby. The name would persist and it even has significant ties to Rogue One.

Not only does one of the songs on Michael Giacchino’s Rogue One score bear the name of Stardust, but it turns out that Galen Erso even named the Death Star project after the nickname he gave his daughter. Whether that naming was to help Jyn later identify the plans from other Tarkin Initiative projects such as “Black Saber,” “Stellar Sphere,” and “Pax Aurora,” or simply a nostalgic nod to his lost family isn’t clear, but it could be said that Galen’s affectionate nickname for his only child would eventually serve to bring down the Empire’s most terrible weapon.

10. She Fled The Empire With Her Family

After living in captivity on Vallt, the Erso’s early years living on Coruscant may have seemed like relative freedom, but it wasn’t quite as free as Orsen Krennic would have them believe. Suspicious of Lyra, Orsen was worried she would eventually convince Galen to abandon his work on kyber crystals for project Celestial Power - a project he was told was for the discovery of a means of using kyber crystals to produce cheap energy. Krennic monitored the family’s communications and travel the few times they even left the Celestial Power facility, until Lyra eventually convinced Galen of the Truth and the Erso’s disappeared.

The family spent  the next few years farming on the remote planet Lah’mu, where the they continued their schooling of Jyn and had her prepared for her role in an eventual escape plan should they be discovered. When the Empire eventually tracks them down, Jyn knows exactly where to hide from Krennic’s Death Troopers until Saw Gerrera finds her.

9. Her Parents Were Pacifists - Her Childhood Toys Weren't

Galen and Lyra Erso were staunch pacifists who refused to get involved with the Clone Wars, or even participate in any research projects that contributed to the war. Galen even turned down research for shielding of capital ships because he saw protecting a warship as a contribution to the destruction of  war, even if protected the life of one side.

Despite their aversion to violence, specifically the Clone Wars, Jyn grew up with many homemade war themed toys similar to what many other children across the galaxy may have played with, including a Jedi Starfighter, an ARC-170 Fighter, and a Jedi Cruiser. Some toys even reflected the current state of the Empire, such as a toy stormtrooper, a TIE fighter, and a Star Destroyer. These toys could have simply been made by Galen to help the family blend in as citizens of the Empire, but that didn’t stop Jyn from at least playing with the strormtrooper, affectionately calling it “Stormie.”

8. She Was Raised and Taught to Fight by Saw Gerrera

Saw Gerrera was first introduced as an Onderonian freedom fighter during season 5 of The Clone Wars where he received training from Anakin and Ahsoka in guerilla warfare so he could lead an uprising against the Separatist invasion of his hime planet, Onderon. After the Republic is consumed by the new Empire, Saw turns his attention to his new oppressor, leading the first wave of resistance against Sheev Palpatine.

He continues this quest after Jyn comes into his care, training the young girl in the same art of war ed down to him by the man that became Darth Vader and his apprentice. The presence of such a young girl in his care didn’t change Saw much, as his brutal tactics persisted to the point that other Rebel cells attempted to distance themselves from his reputation. Even so, he trained Jyn to be one of his best soldiers and fight on the front lines.

7. She Was Eventually Abandoned by Saw

Jyn fought under Saw Gerrera for over 8 years, learning the art of sabotage, assassination, use of explosives, handling of firearms, hand-to-hand combat, and a variety of other tactics of warfare and survival. Even as a child/early teen, Jyn was depended on for a variety of missions, even if the brutality was too extreme for young teen to witness, much less commit.

When Jyn was 16, Saw gave her a blaster and told her to wait for him in a bunker, but he never came back for her. Already fiercely independent, Jyn set out on her own, abandoning Saw’s “cause” and traveling the galaxy under a variety of aliases, such as Lianna Hallik.

With Saw Lucasfilm had bigger plans for Saw than just what appeared on screen in Rogue One, so, like Felicity Jones, don't count Forest Whitaker out of future films.

6. She Wanted Nothing to Do With Galactic Politics

Like her parents, Jyn had a desire to stay out of galactic politics after separating from Saw Gerrera. Unlike her parents, it wasn't because she’s a pacifist. Jyn still got into plenty of trouble, she just didn’t care to hitch her wagon to any particular cause. Having seen the brutality of both Saw Gerrera and the Empire, she assumed neither side was desirable and just looked out for herself.

This disillusionment leads to her distrust seen at the start of the movie. From her perspective, her mother was killed by the Empire, her father apparently ed the Empire as a scientist, and her guardian, Saw Gerrera, was losing sight of the very humanity he was fighting for in his conquest against the Empire. It takes truly seeing the the hope at the heart of the Rebel Alliance in leaders like Mon Mothma to get her to care about a cause again.
