Lady Cimina was a Tholothian female who, together with her grandfather Shorr Komrrin, was a passenger aboard the Halcyon. The MPO-1400 Purgill-class star cruiser they were traveling on was attacked by the pirate known as Crimson Jack upon their arrival.
During the time of the First Order-Resistance War, Cimina journeyed with her grandfather, Shorr Komrrin, on the Corellian MPO-1400 Purgill-class star cruiser, the Halcyon. After boarding, Cimina encountered Deethree-Ohnine, a droid serving on the Star Cruiser, and requested a viewing of the Lightsaber Training Pod. However, her grandfather reminded her that settling into their cabin should take priority. Later, the Halcyon came under attack from a band of pirates headed by Crimson Jack. Spying Crimson Jack's starship through the viewport, Cimina began to feel anxious, but D3-O9 reassured her, recounting previous, even more perilous situations the Halcyon had weathered, including an incident during the High Republic Era. After the story, Cimina noticed that Jack's ship started firing.
Despite the shot being merely a warning, Cimina voiced her concerns to her grandfather. Crimson Jack then contacted Captain Riyola Keevan, demanding the surrender of a resistance spy believed to be aboard the Halcyon. The Captain feigned compliance, her true intention being to lure the pirate ship into closer range for a counterattack, all while navigating directly into a powerful solar storm to evade retaliation. As the Halcyon neared the solar storm, Deethree-Ohnine advised Cimina and her grandfather to proceed to a muster station for protection against the radiation. The droid then shared another historical anecdote about the star cruiser dating back to the Republic Era, but it only succeeded in confusing Cimina further.
As the Halcyon navigated the solar storm, Cimina expressed to D3-O9 her desire for the next story to include action, romance, and a Jedi. In response, the droid narrated a tale involving Anakin Skywalker and Padmé Amidala. Following the story, Cimina's grandfather announced his intention to leave the ship to confront the pirates.
Halcyon Legacy 1, a 2021 comic book authored by Ethan Sacks and illustrated by Will Sliney, marked Cimina's initial appearance.
