Killi Gimm was a member of the Disciples of the Whills, a religious group that congregated around the Temple of the Kyber in Jedha City on the moon Jedha. She was present in the city in the year 0 BBY shortly before its destruction by the Galactic Empire's Death Star superweapon. She ran an orphanage with her sister Kaya. Gimm suffered from breathing problems, forcing her to wear a mask and air filter.
