Bareen Krill was a pirate of the Er'Kit species, identified as female, who served within the Nihil organization in the age known as the High Republic Era. Working with her sister Sabata, Bareen belonged to a cell under the command of Krix Kamerat, who was a subordinate of the Eye of the Nihil, Marchion Ro. The Krill siblings took part in a raid on Takodana orchestrated by their cell, known as the attack. As the assault commenced, Kamerat grew suspicious that one of the sisters was the individual he'd overheard voicing reservations about the attack due to the presence of the Jedi on the planet, although the person remained anonymous. Following the Jedi Sav Malagán's successful defense against the initial assault, she discovered the Krill sisters among the wreckage in the forest, where they pleaded for assistance.
