In the mirror universe, Corbin Entek was a Cardassian male who lived during the 24th century. In the 2370s, Entek was a senior operative in the Obsidian Order and had a "wire" device implanted in his brain to help him withstand torture.
On Natima Lang's orders, Entek assassinated Director Tekeny Ghemor and forced Ataan Rhukal to confess to the crime. Using Taran'atar to threaten Entek to confess, Iliana Ghemor and L'Haan tortured Entek, recording his confession on a isolinear data rod. Entek committed suicide several hours later. Ghemor would later show the recording of Entek revealing his actions and Lang's involvement to Regent Martok, who killed Lang when the truth was revealed. (DS9 novel: The Soul Key)
