A human strong in the Force, Rena was a member of the Jedi Order during the High Republic Era. In the year 132 BBY, Rena, along with six other Padawans, participated in a lightsaber combat lesson held in a training room within the Jedi Temple located on the planet Coruscant. As their instructor, Jedi Master Lakshay, moved among them offering guidance, Rena and the other students practiced a routine using bokken sabers. The session concluded as a chime sounded, prompting Lakshay to announce its end.
After the class, Rena and the other students bowed to Lakshay, who returned the gesture before requesting Rena and fellow Padawan Daro to demonstrate their opening stance. During the training, Rena was attired in white and gold Jedi temple robes complemented by a brown belt and brown boots. The Padawan's belt featured a green sash, matching the color of their lightsaber.
The character of Rena made an appearance in "Day," the fourth episode of the live-action television series The Acolyte. This episode was broadcast on Disney+ on June 18, 2024. The specific identity of Rena among the six human Padawans shown in the class remains ambiguous. However, prior to the episode's release, Rena's character was introduced in a trailer that was exclusively presented at Celebration Europe during the Lucasfilm Studio Showcase on April 7, 2023.
