Borum was a Bajoran. During the Occupation of Bajor he was imprisoned on Cardassia IV. He remained there even after the Occupation ended. He was held, along with his close friend Li Nalas, at the Hutet labor camp. In 2370, he convinced a Cardassian maintenance worker into giving Li's earring to Rionoj, who made a promise she would deliver it to Bajor. Being unable to get to Bajor, she delivered the earring to Quark on Deep Space 9, who then gave it to Kira Nerys. This let her know that Li was still alive. Borum was played by Michael Bell. His name comes from the script.
