Levak was an Andorian chan or thaan who served as grand counsel to the Andorian government in the mid 24th century.
In 2365, following the death of King Collev and his son, Bregev, Levak attempted to take the throne, with the support of the Absolutists, the old guard who had long supported Collev. While Levak had previously made unconvincing claims of his right to the throne, he was favored by some over Yevan, the legitimate heir. Ultimately, Yevan struck a deal with General Hargrev, Levak's key rival, to stop Levak's coronation ceremony, and install Yevan instead. (TNG - Enterprise Logs short story: "The Captain and the King")
