A marauder and slicer of the Nihil, Quin was a female Bivall who achieved the rank of Cloud in Lourna Dee's Tempest, also known as the Tempest Runner. During the Battle of Galov, when the Galactic Republic and the Jedi Order attacked Dee's flagship, the Lourna Dee, Quin was among the captured Nihil. These prisoners were then imprisoned aboard the prison ship called the Restitution. While on the Restitution, Quin encountered Tasia, a Storm also belonging to the same Tempest, and even Dee herself, whose true identity was unknown to her Jedi and Republic captors. Tasia, intending to exploit her knowledge of Dee's real identity, later shared this secret with Quin. Despite this revelation, Quin chose to remain faithful to Dee and eventually rejoined the Nihil alongside her.
Shannon Tyo provided the voice for Quin in The High Republic: Tempest Runner, the audio drama from 2021 authored by Cavan Scott. Her visual depiction first appeared in Star Wars: The High Republic, specifically in its tenth issue of the comic book series.
