Jysella Horn

Jysella Horn, nicknamed Sella, was a female Human Jedi Knight in the New Jedi Order. As of 43.5 ABY, Jysella carried a blue-bladed lightsaber. She was the daughter of Corellian parents, Corran Horn and Mirax Terrik Horn, and the younger sister of Valin Horn. In 43.5 ABY she was one of the first Jedi to succumb to a mysterious illness.

Early life (16 ABY–40 ABY)
Jysella was born around 16 ABY. By 25 ABY, she was a student at the Jedi Praxeum on Yavin 4, and she had spent more of her young life being trained there than she had living with her parents.

After the Yuuzhan Vong attack on Yavin, Jysella spent a number of months aboard her grandfather Booster Terrik's ship Errant Venture with her family, before being moved to the Shelter base in the Maw with the other Jedi children. At the end of the Yuuzhan Vong War, she was still grouped among the younglings, but she was one of the many Jedi who gathered in the Jedi conclave on Zonama Sekot.

By 40 ABY, Jysella was a Jedi Knight on active duty. As tensions between Corellia and the Galactic Alliance developed into an interstellar crisis, Luke Skywalker tactfully assigned her to a mission far away from her homeworld, to avoid a conflict of loyalties when the Jedi were called on to serve as Alliance commandos and starfighter pilots in Operation Roundabout and subsequent missions.

Psychosis (43 ABY)
In 43.5 ABY, Jysella was the third known Jedi to become ill with the mysterious Force psychosis that afflicted both her older brother Valin and Jedi Knight Seff Hellin. During an attempt to seek information on the illness with Master Cilghal, Jysella snapped and immediately saw the Master as an impostor. Unlike her brother, who experienced intense anger, she was motivated by fear. Jysella attempted to breach the temple and when evaluating the situation flow walked into the future and saw her path of escape. This knowledge allowed her to know exactly where the secret security droids where hidden at the temple's entrance, and she quickly disabled them.

Jysella continued to flee the temple, Force hurling pedestrians and screaming in terror that those whom she knew best were not themselves. Two of her best friends, Bazel Warv and Yaqeel Saav'etu, who had also been Valin’s best friends, were on the scene and quickly attempted to stop her once they realized she was afflicted. The two Jedi were unsuccessful and Jysella was apprehended by GA security. The entire scene was recorded by journalist Javis Tyrr. Chief of Staff Natasi Daala arrived soon after and addressed the crowd; explaining that Jysella was now under GA jurisdiction and would be frozen in carbonite alongside her older brother.

When a group of Jedi executed a court-approved document to visit the entombed Horn children, the group, along with the press, discovered the two Jedi displayed over an aquarium in the main office lobby of the Galactic Justice Center. Jysella was eventually freed from her carbonite imprisonment along with her brother Valin shortly before the Jedi Order overthrew the Daala regime, though they both continued to suffer from their ailment, possibly due to their being frozen.

Behind the scenes
In an online chat (and thus not part of the canon), Michael A. Stackpole revealed that Jysella Horn is named after her maternal grandmother, Jysella Terrik. This was later confirmed and added to canon in the Scum and Villainy sourcebook published by Wizards of the Coast where her maternal grandmother is named.

Jysella's age is nowhere closely defined in canon, though the fact that she is not mentioned in Specter of the Past, Vision of the Future or Star Wars: Union suggests that she was born no earlier than 19 ABY. In fan fiction, she is often depicted as being closer in age to her brother Valin than seems possible from canon, which has led to many fans believing her character to be older than she is. However, some fans have also underestimated the range of her possible age, placing her birth closer to 25 ABY than seems implied at her introduction in Dark Tide I: Onslaught.

The preview at the back of the novel Outcast includes an excerpt from the forthcoming novel Omen, which features Jysella as a prominent character. The preview, written from Jysella's point of view, states that Jysella is ten years younger than Valin, making her birth year around 23 ABY. However, when Omen was released, this information was changed to 3 standard years, putting Jysella's birth year around 16 ABY.

On page 362 of the hardcover edition of Vortex, her name is misspelled as "Jysell Horn".
