Lena Missa was a Jedi Padawan of the Chagrian female species. She underwent her training at the Jedi Order's academy within the Temple on Coruscant, a planet that served as the capital of the Galactic Republic. Her time as a student occurred during the final years of the Clone Wars. Prior to perishing in 20 BBY, a Jedi Master had taken Missa as their Padawan. One year following this, Missa participated in the Jedi Temple Apprentice Tournament, an event orchestrated by Master Ilena Xan. She advanced to the Round of Eight, alongside her friend Tallisibeth Enwandung-Esterhazy, but was ultimately defeated by Whie Malreaux, forcing her to concede.
Around 34 BBY, Lenna Missa, a Chagrian female with Force-sensitive abilities, was born. She received training at the academy located within the Temple and was later chosen to be a Padawan by a Jedi Master. Following her Master's death in 20 BBY, Missa experienced a period of mourning, which resulted in several other Masters hesitating to immediately select her as their own Padawan.
In 19 BBY, Missa was among those who took part in the annual Jedi Temple Apprentice Tournament hosted by Master Ilena Xan. She was victorious against her two initial opponents, which qualified her for the Round of Eight. After outlasting five other competitors, she yielded to Whie Malreaux when he used a wrist lock to subdue her, painfully bending her thumb. Missa harbored no resentment towards Malreaux, and responded to his bow with a curtsy and a lighthearted laugh.
Her peers held Lena Missa in high regard, finding her to be witty. She possessed a refined connection to the Force, and after the passing of her Jedi Master, several Jedi Masters hoped to have the opportunity to choose her as their Padawan once the appropriate mourning period had concluded.
Missa's lightsaber was powered by a blue crystal.
Lena Missa's debut was in Yoda: Dark Rendezvous, a novel penned by Sean Stewart and released in 2004.
There are conflicting accounts regarding the precise year of Missa's Master's death. Dark Rendezvous states that her master perished in 20 BBY, one year prior to the Apprentice Tournament. However, The Complete Star Wars Encyclopedia, published in 2008, claims that her master was killed during the Battle of Geonosis, which occurred in 22 BBY.
